There is a long standing thought by many, who belive that revolvers in general are substantially more reliable that semi autos.
This is just some food for thought.
This is a pic of my firing pin from my 442 J Frame. The nose broker completely off.
When it happened the FP was stuck in the forward position, not allowing the cylinder to rotate when the trigger was pulled. I was able to wiggle it back in the bushing, and rotate it, but it simply would not function as it should.
I initially assumed that maybe it was a bur, until I took it apart.
Use anything hard enough, and it will break. I have been using this gun since 2000 and the break is not part of any faultiness on S&W's part (in my opinion), it is just wear and tear on a 17 year old gun.
Fortunately S&W was super easy to deal with and a new FP is on it's way, as of last Monday. Great customer service experience BTW.
