I'm a total 1911 nut. I built my carry gun... bought a rock island frame/slide kit... The rest is all Wilson Combat... ALL Internals... Except the barrel which is a Nowlin match grade unit. OF COURSE It's in the ONLY caliber that a 1911 should be in... .45ACP... anything else in a 1911 is blasphemy!!! I would post pics but my digital camera died... Anyone who carries JMB's greatest handgun, i'd love to hear your thoughts... Along with those of any anti-1911 guys/gals out there.
