And it works well. My M40A1 is now back to being my duty weapon. I ordered a Safariland model 6280 holster for the original M series. I had to remove the tension screw as it is right in line with the tac rail. Then since the gun still would not fit I used a heat gun to soften the kydex. Once the Kydex was soft, I just inserted the M40A1 and stretched the Kydex where it was tight. The holster is still a bit on the tight side, but the gun does come out pretty damn fast :twisted: as evidenced by one of the calls I took last week.
