The top one is an ATI Compact in 45acp which I just picked up tonight. It will see the range tomorrow. Dry feeding, it strips and ejects snapcaps, round nose, and Hornady XTPs. With tax, I paid $463 out the door.
The bottom is an RIA Compact in 9mm, and it shoots beautifully. The two-tone was a bit hard to find, and I picked it up used.
Fit and finish on both are very nice, slide to frame on both are a tight fit, no slop. Triggers are both smooth and break clean.
The RIA has a 4" bull barrel, the ATI is a standard 4.25" barrel with bushing and 1/2 length guide rod.
The 9mm holds 9+1, the .45acp holds 8+1. The RIA weighs 2lbs 10oz, and the ATI weighs 2lbs 13oz. For comparison, a Glock 23 loaded weighs 2lbs, a full size MilSpec Springer loaded weighs 2lbs 15oz, and a Sig RCS with it's alloy frame weighs 2lb 4oz loaded.
Each one came with one mag, the RIA came in a plastic carry case, the ATI came in a padded cardboard box.
So far, I'm happy with them and would recommend them to anyone.
