I have a baker's dozen plus 2 1911 type's dating from 1916 to 2011. There are a couple that seldom see sunlight but none are 100% safe queens. 9mm's, 38Super, 40S&W, 10mm, 45ACP's. Mostly Colts and SAs but a LB and a Brown. From mil-spec to GC to semi-custom. The single 1911 type I ever had problems with was a Kimber Ploymer Custom. I truly think this gun was a mistake by Kimber ... maybe a shot at Glock? New or used, I disassemble - completely - inspect, polish (if deemed necessary), lube and reassemble. I shoot various factory ammo and my reloads (WST pushing 180 - 230 g pills). I will change sear/trigger springs to lighten pull and recoil spings if I do not know condition or want to go heavier or lighter. And, have been known to tweak the lips on a magazine. Oh, use several different magazine brands. Do not even check what before I shove it into the gun. Otherwise, shoot them. I did swap a bbl in a 38Super as it was the old Colt headspace-on-the-rim type and the gun was inaccurate. Ran good but shot horribly. Nowlin solved that. Do it all myself. Am I just lucky? I read about a lot of problems. Are we just hearing the bad and ungly while the good just keep quiet????
