I recently puchased a remington 1911 R1. I wanted to know what parts should be replaced if any for maximum performance. I like it fine now but I like to change things and make them my own. So my goal is to make the most reliable/durable 1911 I can. Im new to 1911s so I dont know the weak points of the gun. Any advice on what usually wears out fastest, whats prone to breakage, or cause of problems?
