I have a Safariland ALS 6360-53-131 holster for a 1911 in STX TAC Black. It is slightly used, and has been upgraded with the improved ALS. There was a problem with the original ALS holsters for 1911's, the ALS would not hold the gun. A slight twist, and the gun would come out. An improved ALS has been installed, and will hold the gun securely. 80.00 shipped.
