i recenently purchased a colt SAA chambered in .357 mag. Shortly after the buy i was talking to a friend of mine and he told me a story about .357 mag colts having reliability issues due to the fact that the frame was originially designed for the stress of the .45 long colt. he said that the frame can weaken and that critical parts (revolver drum, barrel.) can need replacing after 10000 shots. Does anyone have any input?
