it would not fit my RIA Tac 3.5 in barrel but I cant remember if the barrel stuck out the bottom and caught on the front sight when I drew or if it bottomed out and left the gun not seated I went to alien gear http://aliengearholsters.com/

Hi Kevin, Yes this will fit a Rock Island Armory Ultra Tac with a 3.5” barrel

Kevin, according to Galco this is designed for 3" 1911's including double stacks. In my opinion it should fit but I would contact Galco to make sure before you order at Galco International - 1 (800) 874-2526 / Local: (623) 434-7070 : 8:00AM-5:00PM Monday-Friday, MOUNTAIN STANDARD TIME
