I took my 422 out to the range a couple weeks ago. And it started to act up on me. The rounds would cycle,but fail to fire when I pulled the trigger. It was not jammed,I would pull the slide back about a quarter inch and release it and the then pull the trigger and it would fire. It was right towards the end of our shooting. So I cleaned it and did not see anything out of the ordinary. So I was wondering ammo maybe. I dont know but nothing worse that a unreliable pistol. Has anybody had problems with a 422 or 622 for that matter like this. I'm getting ready to call Smith and see what they say.
