I have yet to have that happen and my CCW is about 25 years old. It is a S&W J-frame.
If it had a malfunction I dont know what I would do... may be have a smith check it out?
I like that you cant limp wrist a revolver.
How ever my wife carries a Sig P238 that she loves. Early on it had a lot of problems and took 3 trips to sig and then finally a trip to a local gun smith to get it to work.
I still dont trust it but I figure she loves it and will actually carry it. I have tried to get her to carry other guns but she says its this gun or nothing... Its been very good since the trip to the smith but its hard for me to trust it.
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 26 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple. Wish my wife did as well...
