Last year when I bought my Sig 1911 TacPac, a friend bought a RIA Tactical (
just like this one) which I suggested after I shot several models that produced very accurate shot groups. To be honest, the RIA produced shot groups at 7-15 yards were on par with my Sig.
Both pistols have reliably fed/chambered various factory FMJ/JHP ammunition to 185-230 gr FMJ/JHP, plated and lead SWC reloads. Friend's RIA Tactical has looser tapered chamber with fairly generous mouth so feeding/chambering even when dirty has not been an issue. We have been running Chip McCormick 8 round PowerMags through both pistols.
After several thousand rounds, RIA is still producing comparable shot groups with the Sig but I have noticed the 15 yard shot groups are a bit larger than the Sig now.
I would gladly suggest the RIA Tactical for an entry level 1911 for accuracy. If you want to spend a little more, there's STI Spartan.
Here are sample targets shot at 7 and 15 yards off my range bag from my initial range testing of
tumble lubed SWC bullets (although these were shot with my Sig, RIA produced comparable shot groups):
