Does anyone own a 10mm

I just started reading about 10mm...

10mm Auto

Introduced in 1983 in the ill fated Bren Ten autoloading pistol, the 10mm Auto has quickly become one of the most successful cartridges developed during this century. The idea originated with Whit Collins, who assisted in the project by John Adams, Irving Stone, and Jeff Cooper, but the credit for keeping this .40 caliber cartridge alive during its youth has to go to Colt for giving it a permanent home in the excellent Delta Elite version of its famous 1911 Government Model pistol.

Jacketed bullets of .400 inch diameter in various weights are available from the major bullet makers. Superbly accurate cast bullets in .401 inch diameter are available from Bull-X (Farmer City, Illinois) and Competition Specialties (Osceola, Iowa).

During 1990, the 10mm Auto gained even more credibility as a self defense cartridge when the FBI abandoned the 9mm Parabellum and officially adopted the larger caliber. Other law enforcement agencies are sure to follow suit. In addition to being an excellent self defense cartridge, the 10mm is powerful enough for use on deer size game at close to medium ranges. This especially holds true when it is loaded to maximum velocities with the heavier bullets and fired in a custom barrel from Bar-Sto, Wilson, or Centaur Systems. When the 150 and 155 grain bullets are down loaded to 1200 fps, the 10mm becomes an excellent cartridge for USPSA/IPSC competition with about the same level of recoil as that of the .38 Super. Recent tests with a Colt Delta Elite fitted with a Centaur barrel and compensator produced consistent accuracy of less than four inches at 50 yards.

found no great advantage
and some police SWAT units
and some SOG's were going
back to .45ACP which led me
to believe I'd be well off
to stay with what I already had.
There are some very nice 10MM's
though, chrome with pearl grips.

The 10mm auto cartridge is a great idea that just never really caught on like it should have with American shooters. Back in the early nineteen-eighties, it seemed to be off to a real good start. It had the blessings of the great defensive handgun guru of the time, Colonel Jeff Cooper. He regarded it as superlative to his beloved .45 ACP cartridge, and stated as much loudly and often, in person and in print. The first auto pistols chambered for the cartridge were based on the Czech CZ-75, a very good design, and the pistols were produced by Dornaus and Dixon, who called the new pistol the Bren Ten. However, the new guns were plagued by a few problems, mainly the lack of magazines. I remember well reading every word that I could about the new pistol and cartridge, but being young, newly married, and broke, reading about it was the best that I could do. Colt and Smith & Wesson chambered pistols for the new cartridge, as have some others, and the Bren Ten was even carried every week of the first season by Don Johnson, the star of the new hit TV series, Miami Vice. Factory ammo energy figures were impressive for an auto pistol. The energy figures for the 10mm showed the cartridge to be more powerful than either the .45 ACP or the .357 Magnum. The FBI even adopted the S&W handgun chambered for the 10mm Auto. It looked like it was off to a stellar beginning. Why it never achieved much popularity is somewhat of a mystery to me. It certainly wasn’t the forty-caliber bullet, as the less powerful .40 S&W cartridge is enormously popular. Recoil could have been a factor, as it can be a bit stiff with the heaviest loads. In the right handgun, however, the 10mm is not hard to control at all, and magnum revolver cartridges are more popular than ever.

One 10mm handgun that has achieved somewhat of a cult following is the Glock Model 20, which is the subject of this review. The Glock 20 is perhaps the most controllable 10mm pistol yet developed, if the gun fit’s the shooter’s hand. The exterior dimensions of the 20 are the same as the .45 ACP chambered Glock 21. It works very well for a shooter with medium to large hands. Small-handed shooters need not apply. That is one reason that the .40 S&W became much more popular than the full-sized 10mm auto. Beginning in the late 1980s and ever since, police forces at all levels of government have been actively recruiting women and minorities into their ranks, perhaps to achieve a more touchy-feely police force, I don’t know. Most women and many minorities are of smaller stature than the average white police officer of years past, when police administrators wanted big, strong officers on the beat. These smaller new recruits usually come equipped with smaller hands. Police administrators wanted a service handgun that would be a one-size-fits-all proposition, and the .40 S&W will fit into a smaller weapon. It also has less recoil than does the big ten. However, the Glock Model 20 is very good at absorbing that extra recoil. The 10mm in the Glock 20 recoils almost straight back, without excessive muzzle jump, and is an excellent platform from which to launch the full sized 10mm cartridge.

The Glock pistol operates from a locked breech that utilizes the ejection port as the rear lockup point. That feature, along with some other interesting design features of the Glock places the gun low in the hand, effectively reducing muzzle jump. It works and works very well at reducing the felt recoil of the big ten. The Safe-Action trigger pull is neither like a single action nor a double action trigger pull. It is somewhat in between. It is quite easy to get used to. There are no levers or buttons to push to make the Glock fire, and that bothers some people. However, and contrary to what some would have you believe, the Glock is no more "dangerous" than any other pistol. The shooter must keep his finger off of the trigger until ready to fire, just as with any other handgun. Pulling the trigger fires the weapon. Simple.

The Glock 20 has a standard magazine capacity of fifteen cartridges, giving a total capacity of sixteen of the powerful 10mm cartridges at the shooter’s disposal. The trigger pull on the sample Model 20 measured five pounds and ten ounces, and was smooth and easy to operate. The barrel length on the Glock 20 measures four and six-tenths inches (4.6"), and has Glock’s hexagonal rifling. The slide is finished in their tough Tenifer coating, which has proven to be very durable over the years.

For testing the Model 20, I gathered an assortment of eighteen different types of factory ammo from three sources. I fired all loads over the screens of my PACT chronograph at a distance of ten feet from the first screen. Actual muzzle velocity will be a bit higher. Air temperature was around fifty-two degrees with a humidity of near fifty percent. The velocities are listed in feet-per-second (fps). Bullet weight is listed in grains. The chronograph results are listed below.

Manufacturer Bullet Velocity
Buffalo Bore 180 Gold Dot HP 1328
Buffalo Bore 200 FMJ-FN 1184
Cor-Bon 180 Bonded Core 1233
Cor-Bon 200 JFN 1071
Cor-Bon 165 JHP 1277
Cor-Bon 135 JHP 1441
Cor-Bon 140 DPX 1352
Glaser 115 Blue 1516
Glaser 115 Silver 1528
Double Tap 165 Gold Dot HP 1380
Double Tap 155 Gold Dot HP 1441
Double Tap 200 FMJ-FN 1225
Double Tap 200 XTP-HP 1216
Double Tap 230 HP 970
Double Tap 180 Gold Dot HP 1331
Double Tap 135 JHP 1509
Double Tap 165 Golden Sabre HP 1394
Double Tap 180 Golden Sabre HP 1259

All loads tested performed very well. The only problem encountered was with the Double Tap Equalizer 230 grain load. Three times during testing the slide failed to go completely into battery with that load and that load only. A gentle tap on the rear of the slide popped it into battery. Everything else fed, fired, and ejected flawlessly. The Equalizer load might have just been a fluke with this particular pistol, and I would certainly try it in other pistols before making a judgment either way. I would recommend any of these other loads to be carried in the Model 20, choosing the one that best suited the situation. The heavier bulleted loads should be ideal for hunting heavy deer, hogs, and black bear. The lighter hollowpoints should work very well for social work. The Glasers are a specialized load from Cor-Bon that are pre-fragmented to create maximum tissue damage with limited penetration. Accuracy was good with most loads tested; better than with other Glocks which I have used in the past. The 10mm has a good reputation for accuracy in quality pistols, and the Model 20 is a quality pistol. I could keep most shots into the two-inch range at twenty-five yards, with the misses being my fault. Most ammunition was, however, expended on rocks and sticks. It was a pleasure to shoot the Glock 20.

The Glock Model 20 is not for everyone, it is indeed a fine pistol for experienced shooters who want more power than is commonly available from the usual choice of auto pistol cartridges. It is relatively light at just 30.9 ounces, unloaded. It is flat enough to conceal well in a proper holster, and the edges are smooth to not get caught on clothing or skin. As is, it is a very good hunting pistol for medium game. For social carry, I would add tritium night sights to the weapon and stoke it with good hollowpoint ammo, as represented by any of the fine loads listed above, but would try any load in the individual weapon in which it will be carried to assure perfect function. The 10mm is a cartridge deserving of greater popularity, and the Glock 20 is a fine platform from which to fire it.

.41 S&W Mag.

Around the end of the 1980's I was at
the range with my M1 Carbine. There
were 2 men there with a brand new .41 Mag.
As I walked past them to check targets
one of them asked if I wanted to shoot it.
I thought that was unusual since we had not talked
at all. I fired 5 rounds and it kicked hard
and I did not like it. Later, as I was getting ready
to leave one of them seriously asked me if I'd
want to trade my carbine for the .41. Thanks but no.
Another unnecessary caliber, good but not needed.

launch as the one's who'd
invested in it had hoped.
Mr. Jeff Quinn seems to have
written some wishful thinking
but that won't get the sales
numbers up as fast as reading
about SEAL teams carrying 1911A1
.45's or any other brand/style in
the caliber.

10mm Auto

I have a Colt Delta Elite which is 10mm auto. I think I uploaded a pic of it on here a while ago. Very nice pistol, 1911 style. That baby has got some punch to it. The 10mm does have great knock down power. Ammo however is expensive and hard to find at times. A box of 50 rounds of just plain old FMJ practice ammo runs me about 30 bucks. It's a round, just gets expensive to shoot.

I just shot remington 00 buck for that. Sometimes even 3 inch magnum 00. There may be a better load, but that's a solid one if you want to see what she will do.

try 3 1/2" 00 magnum loads (if your chamber will except it, I think 870's only go up to 3"). Those things will wake you up! whenever I take someone new shooting, I hand them my mossberg 835 ulti-mag loaded with 2 3/4" clay loads and hide a 3 1/2" mag load in the middle. When they're not expecting it, it about knocks them on their ass

Ebear, 12 ga ammo

For shooting paper and getting to know the controls and handling of the gun, go to Wal-Mart where you can buy the 100 rd value packs of shotgun ammo. Those are the rounds not kept behind the counter and they never seem to run out. Get the #7 1/2 shot, I think it's about 22 bucks for 100 rds. Also get a couple boxes of 00 Buck and 1 oz Slugs. The slugs kick like a summabitch, but seeing that big goddamn hole in the target is pretty nice. Also, save some milk jugs and laundry detergent bottles. I assume you're one of the few Meskins who actually does laundry. If not, go dumpster diving at a laundromat. Fill those suckers with water, get the caps on tight, and pop 'em with the slugs. The cap of the laundry detergent bottle will pop off and go about twenty feet in the air. You will be a changed man, I guarantee it. I ought to post a video of it. Different brands of buckshot shoot differently, just like any other ammo, so you'll want to know which works best in your gun if you're keeping it for home defense. Mine likes Federal, which sucks because that's the brand of buckshot that Wally world doesn't get very often. Winchester is still plentiful, but it doesn't pattern well in my gun. Granted, inside a room it won't matter, but I've got a back door (STOP IT!!!!) about 18 paces away from my bedroom and even though most of the charge should hit the bad guy, it's not as tight a pattern as I would like.

the sheriff's department regularly
cleared out all the old ammo they carried
in the trunks of their cars and gave
it to the deputies to practice with. My Dad
did not think I needed anything but
the free stuff. I did have a choice
of either my J.C. Higgins or the
issue Model 12 pump riot gun but that
little sucker left my shoulder a little
sore and very purple.

was a single shot H&R 12 gauge. You talk about kick! Lightweight gun, plastic buttplate, 3" #4 turkey loads, yeah baby. I do have a funny story with this gun, though. I'm the oldest of five kids and of course we grew up hating each other. My sister wanted to go shooting with me and wouldn't stop bugging me, so I took her out one day and we shot my 10/22 and my SKS. She was afraid of the shotgun, so I kept reassuring her that it was fine, and showed her by firing it one-handed so she finally agreed to. What she didn't know is I was loading the gun with the 2 3/4" #7 1/2 birdshot to shoot one handed and when I gave the gun to her, it had one of the 3" #4 turkey loads in it. She put the toe of that hard plastic butt right on top of her tit, cocked the hammer, touched it off, dropped the gun, started crying, and walked home. She never asked me to go shooting again after that. Ah, younger siblings are a hoot.

10mm

I've got a 10mm barrel for a g21sf, so yes I do. I keep it loaded with corbon hunting ammo when I'm up in the mountains or the rim

OUCH, I was the youngest of 4 and I caught hell
from the older ones but usually it was harmless
or almost so. My oldest brother tried to shoot me
with a .22 rifle, the dumbass missed by almost a foot
leaving a hole in the livingroom wall.
2 days later I tried to find his spleen with a
hatchet but he ran pretty fast.
Ah, the "good" old days of childhood.
