Surefire mr09 weapon light mount for h&k pistols - Surefire MR09 X200 WeaponLight Integral Mounting Rail for HK USP 9mm/.40/.45 Full Size Handgun

I bought two of these mounts for two H&K pistols that I own. On my USP 40 full size it fit perfectly with no problem. But on my H&K USP 45 Tactical the rail was narrower and the mount had to be filed dow where the two halves meet to allow it to clamp down tightly. I called Surefire and they told me to go ahead and do it and they would back me. It worked out fine and the mount is now solid but it took some careful work.
Pros: solid and well made
Cons: needs modification for some pistols
