Chris,
I have trigger over travel screws on both M83s and M97s -- To me it it isn't worth the $64.00 that FA now charges for this option, and they make me uneasy on a hunting or self defense gun.
Ken,
I've broken the hand spring, trigger spring and bolt spring on a .45 Colt M97 and a bolt spring on a .475LB. Some time ago, Mark Hargrove said that FA had upgraded the spring material on these parts. Each time, FA supplied the spring, and I had a local guy install it.
