Just picked up my 40 cal. PX4 Storm. I went to the range this past Saturday and It kept jamming on me. I was using S&W reloaded ammo. Was that the problem?
Many new guns needs a bit of a break-in period. If it's still doing it after the first 200 rounds or so, then it may be a problem. There are a few things to check before deciding to get rid of it.
- Is it lubricated?
- Is your grip correct?
- Have you tried different ammo?
By the way, S&W doesn't make ammo. All .40 cal ammo for that gun is .40 S&W
