I've been looking for a compact molded holster that can retain my K40 without risking it slipping out, but will also release quickly. I like the lever-release for the trigger finger that the Serpa uses; it seems very intuitive. Unfortunately, it seems that Blackhawk doesn't make a Serpa for the K40. Does anyone know if any of the Serpas that are made for other handguns will fit a K40? Alternatively, can anyone recommend a similar style holster (Kydex, polymer, etc.) that has a positive-retention system like the Serpa? T.I.A. -- Robert
