Glock makes great guns. I love glocks but if you haven't fired a 1911 you should try one. You will be completely satisfied with your Glock 30, reliable, accurate and practically indestructible, easy to clean and plenty of aftermarket parts and accessories. By the time I'm done I'll have every 3rd Generation Glock except for the 18 and the 7.
In addition to being a BIG Glock fan I'm also a pureist. I like 1911's in .45, Kimber, Springfield S&W, Colt, Les Baer & Ed Brown, I also like HK & Sig in .40, S&W/Ruger revolvers in .38, .357Mag, .44Mag & 460.
