I said that few 1911's are as tight as what I was comparing a rotating barreled pistol to, now I'm not so sure. I checked all of mine, they are all tight when in battery. Three points at the back (Top of barrel lugs area #1, both lower lugs #'s 2 and 3) and one at the front where the top of the barrel is tight against the bushing. I suspect now that most 1911's are as tight as these unless they are shot loose, like after 100K rounds.
CNC produced 416 stainless triggers to replace the plastic triggers on Colt Mustangs, Mustang Plus II's, MK IV Government .380's and Sig P238's and P938's. Plus Colt Mustang hardened 416 guide rods, and Llama .32 and .380 recoil spring buttons, checkered nicely and blued.
