Or, should I have a gunsmith do it? My Remmy R1 Enhanced has the sloppiest trigger I've ever encountered on a 1911! I did some research and found this is not uncommon as Remington possibly put the same small trigger on all their R1's to get them on the market. Anyway, in that search I found that this EGW trigger is perfect for taking out that gap between the top of trigger and housing. Can I just disassemble the R1 and install this trigger without replacing any other parts? I'm not a gunsmith and outside of changing out grip bushings/screws, have done no work on 1911's. What say you handy folks?
