I have a rock island tac ultra ms 1911 in 10mm. It has a uncut/unique slide and full length rail. Im looking for a holster that fits it. Anyone have suggestions? Most places i contacted say they dont have one to test fit. I prefer a second retention but anything that works is great. Last resort i know i can get a leather one custom made im looking for anything anyone knows fits from like safariland, aliengear, blackhawk,etc etc etc. Thanks fellas
