Good report. I'd like to hear how it handles hot loads like DT and Underwood. Surely they didn't use a .45ACP spring, but, you sometimes get what you pay for and RIA is new to the 10mm game. I've only had one experience with Amrscor's customer service, and it was pretty positive. Front sight was so loose it started sliding out when I first took it to the range. They paid shipping both ways and polished the feed ramp and throated the barrel, as well as tuned the extractor while they had it just for poops and giggles.
