The all-round talent
The GLOCK 19 is ideal for versatile use through reduced dimensions
compared with the standard pistol size. With the proven caliber
of 9x19, it has found worldwide distribution in security services.
In addition to being used as a conventional service weapon, it is
suitable for concealed carry or as a backup weapon. For instance,
many of the elite pilots of the USAF trust the GLOCK 19 for their
efficient defense in emergency situations. (from Glock website)
I have been shooting the Glock 19 since the mid 1990s and I like
everything about this gun except for one thing. Since it is a bit
wider than what is completely comfortable in my hand, if I shoot for
a long period of time, my hand gets' tired. However, it takes a long
time before that happens.
