My 2 inch smith kit gun has gone well over 50k rounds and is still going strong. It's an old adjustable sighted RB model. I use it for DA practice for my other J frames. Fits same IWB holsters. Again, stupekid is fos and I just PROVED it.
The M21, if you dry snap, you will RUIN that one chamber it has or BREAK that pinned in firing pin. Just another FOS stupekid post.
