I'm not well versed on this site's search function, so please forgive my question if it has been addressed before.
Just how common are cracked frames in S&W J-frame airweights? When it happens, is it more likely caused by high round count, high +p round count, or low round count coupled with over-torqued barrels?
I have a 642 that I use for training and a seperate 642 for carry. The first gets shot a lot and the second almost never. This is due exclusively to my concern over cracked frames.
Even the steel j-frames don't seem to be immune, yet I have never heard of one in an SP101, and I thought Ruger's investment castings were less dense (more brittle?) than Smith's forged frames.
