A buddy of my brought over a S&W 622 that will not fire sometimes. He has had it to three different smiths and they've replaced parts, but nobody can get it fixed. The pistol is really starting to frustrate me so, I need to ask for some help. If you load both mags it'll fire maybe three times, eject the spent round, load a new one, but it wont fire. What makes it really frustrating is it might go thru both mags just fine and then you'll get a failure to fire on the second round after you reload the mags or it might be the fifth round after the second mag. I've tried four types of ammo so that's out. What do you guys think? Anyone had this problem?
