Whoever the Blackhawk rep was, well, they are a freakin' idiot because I have carried a Kimber 1911w/ rail in a Serpa holster for the past 3 years. I called blackhawk and asked, they told me that all of their 1911 holsters and beretta 92/96 holsters fit with or without a rail. The only gun I have found with a rail that won't fit the Blackhawk serpa is one built on a Caspian Recon 1911 frame with rail, the rail is lower on the frame to add extra weight to the front of the gun. I have two 1911 serpa holsters one is 3 years old and one is about 3 months old, both fit a 1911 with rail. You must have just gotten a hold of a moron at blackhawk that day you called. Other suppliers are bladetech and fobus makes a evolution holster to fit 1911 w/rails. I'd personally go for the blackhawk, i've tried the others and like it the best for comfort and security.
