Thanks guys, I like the Springfield for namesake but have heard lots of RIA owners who love their Rocks. They are priced about the same but I would want to change a few things on the springer. Namely beaver tail safety, hammer and trigger. May polish the feed ramp if needed. How hard is it to change these on my own? Do I need to do more than just drop in parts or should I have my gunsmith work on it for a cost? Money is a factor of course wish I could drop high dollar on a Colt or WC but just can't.
