On the colt combat commander I switched to a GI style guide rod from the FLGR. I added a flat trigger to both from 10-8 performance. I replaced the thumb safety on the CCC.
On both I have a Novak front sight night sight and a Heine straight 8 rear ledge.
I added a two-piece Ed Brown magwell and ambi safety on the RG. I also added the Wilson combat front strap checker piece of metal to hold me over before sending it to get checkered.
