I bought this RIA so I could learn some things about the 1911's. So far I have changed all of the trigger & hammer related parts, added a magwell & a beavertail. I think I'll up-grade to a better barrel & bushing when the weather turns cold this winter & I have more time to work on stuff indoors. This is a great hobby! There wasn't anything wrong with the RIA to begin with, I bought it new & it was a good gun. I just wanted to expand my gun skills.
