My LGS has a matched Caspian stainless steel frame and slide, it's actually an early Sig GSR production overrun. I need another 1911 so I'm considering buying this and doing what I can and letting my gunsmith do the barrel/bushing fitting. I've never assembled a 1911 before so the learning experience would be valuable to me. Given the fact I haven't done anything like this before would you guys suggest I invest the time and money in this or would it be best to simply purchase a complete pistol? Thanks in advance.
