I like 1911's, almost all my semiauto's are that type, or similar JMB designs. I hadn't really paid attention, but my true 1911's are all internal extractor and the others are external. I have several makes, but no S&W and no Colt 1911, although I do have a 1903 Colt. I also went for the different caliber offerings, and have them in 9mm, .38 Super, .40S&W, 10mm and .45 Auto.
