Picked up a RIA Tac awhile back and it was shooting way low and left. Sent it back to Armscor precision for Arnel to take a look at. He wound up putting a new slide, taller rear sight, tuned the internals and polished the feed ramp and barrel. I put about 150 rounds if WWB and 75 rounds of my 200 grn swc. Not one hiccup, and now shoots to poa. Need to spend a little more quality time with her, but I think she is a keeper now. Anyway, wanted to give Arnel, and Armscor 2 thumbs up for their outstanding customer service, and commitment to providing a quality product, especially for the price. Thanks.
