Lovin this gun. I have owned it for 2 months now, when I got it I took it completely apart and polished every mating part. Replaced:
Front sight
Guide rod to stainless steel with coil spring
Grips ( I made them from Buckeye Burl Wood)
Mainspring to 13.5#
Extended Firing Pin with reduced spring from CGW
Magazine bottom plate
Firing Pin Block spring from CGW
I think at this point I need a new rear sight to move the group higher. This is at seven yards, off hand, 20 rounds of 124 grain and 20 rounds of 115 grain ammo.
Ok! you cought me. My bad, yes I did hang the target upside down. Oh! By the way not one hangup, smooth as butter.
