Been doing my due diligence, figuring a budget, watching auction prices etc, taking my time so I get exactly what I want in a 1911. Currently own a GSG. 22lr 1911, like shooting it. Here is my question, I'm wondering about whether I want to go with .45 or 9mm. I just don't think I want to get into a 4th caliber of gun(.22lr, 9mm, .38sp currently) Looking at Rock Island, I see they are a parkerized finish, the GSG which is a working/practice gun that has some holster wear might need refinished at some point. Was also looking at Springfield Armory, what would I notice as a big difference between the 2, other than maybe $400 in price? Machining? Parts difference? I like the skeletonized trigger. Again, in the look and learn phase of the search. Wanna kill these ads? We can help!
