WOW! Look what I started... LOL Fact of the matter is, ANY gun can jam. The only gun that I own that hasn't jammed (yet), is my M77 that I've had for 2 weeks. My SR9, 10/22, Rem. 870, Rem. 572, and my SP101. They all jammed for various reasons, i.e., bad ammo, limp wrist, dirt, GUN MALFUNCTION, etc. Anything mechanical, especially one with tight tolerences & timing like a firearm, can fail to operate.
Now, we all should know how to make the smaller chance of this happening our responsibility.
89grand, I wasn't trying to imply that your P944 isn't a great, reliable weapon. But, so are my SP101 and my 870. I trust my 870 more than any other gun I own, but it has jammed because of dirt being blown in by the notorious Oklahoma wind. It's a fact of life that will always be there, for all of us.
