D10
EGW Flat bottom firing pin stop. Not really flat. Changed 22 lb recoil spring to 20 lb.
EGW Barrel Bushing fitted to barrel and slide.
Wilson 0.200 Slide Stop. Rear lockup loosened up after 200 rounds of Sig Elite FMJ with OEM.
Nighthawk solid trigger. Took out up and down movement and side to side play in trigger.
Stoned trigger bar, disconnector face, trigger slot in frame.
Colt sear spring. Only adjusted grip safety tension.
Polished top of hammer. Felt rough when rubbing on the bottom of the slide. Wear in finish is triangular, much wider on left compared to right side.
Match
Wilson gunsmith fit barrel bushing. Both OEM barrel bushings were very loose to barrel and to frame.
EGW slide stop. 0.200 OD. The original felt right enough at first. Loosened up and barrel rear could be pushed down after a couple hundred rounds.
Nighthawk 17 lb recoil spring
Nighthawk solid trigger, fitted in height. Zero slop now.
Polished trigger bar, disconnector face, and trigger bar slot in frame.
Colt sear spring. Only adjusted the grip safety Leaf.
Triggers in both break at 3 1/2#. With fitted barrel bushings, hard rear lockup, and acceptable slide to frame fit both are good enough for anything short of Bullseye use.
The extractors, barrel throat/ramp, and sights have been fine. Rear sights have LocTite now.
