So I have a two year old RIA Tac which looks like they've renamed the Rock Standard but kept the same product code. I was wondering if anyone had some essential upgrades that they think I should do. So far i'd like to put a magwell on, different grips, a stainless solid trigger for aesthetics, a non-ambi extended safety, and an extended slide stop. It's pretty damn accurate and hasn't given me any trouble.

Or should I even bother and save up for a DW RZ-45 or something? Which well then probably snowball into me saving for a $2500+ 1911...

This right here I have never seen them so cheap would act fast will be better then anything you can do to you RIA IMO short of a full build
