I have both ATI guns and RIA (Armscor) guns from the Philippines. Both are excellent, utilitarian guns, but, of the two, I think the ATIs, made by Shooters Arms in Cebu City, Cebu have a slight edge over the Armscors in both fit and finish.
On my trips to the PI, I had ample opportunities to examine ATIs in Shooters Arms outlet stores which are located all over in almost every province. In addition, spare parts were available for sale in the store, which I examined and found to be of superior quality, at least in appearance and finish. I almost bought a Commander hammer while there , but, after converting from pesos to $$, I changed my mind. LOL!!
(Kind of pricey.)
Here in the U.S. I have a couple ATIs, the latest of which was the 1911 Wild Bunch shooters model and I have been very pleased with it. I did a couple of tweaks to it to make it look more like an original 1911 (Colt 1911 slide, 1911 short hammer, etc.), and all parts were total drop ins. Neither of the ATIs has given me an ounce of trouble for general shooting and plinking.
My Armscors (RIA) have also been trouble free as is, and I have also purchased about a dozen or so RIA frames from Sarco which I made up into utility shooters using surplus parts, Brazilian slides, etc. They, too, were 98% drop in, and turned out to be excellent shooters.
IMHO, I think they are excellent values for the money, and certainly light years ahead of the junk that is coming out of Turkey.
