Hey HK people. I thought I would show you a comparison of the GG&G USP rail adapter vs the Surefire MR09 rail adapter for the H&K USP when using an X300 Surefire light.
For a long while, I just accepted that the GG&G rail was the only affordable and decent option. I used it on my USP for 6 months and just found that my hands were not big enough to really reach the switch in front of the trigger guard. I could activate it, but it was not easy to get to.
I found (and severely overpaid for) a new surefire MR09 adapter on ebay last week, and it is a much nicer mount than the GG&G, plus it moves the x300 backward enough that I can easily get to the switch with my medium sized hands.
Here is a picture comparison for those curious.

You can see that the MR09 tucks the light closer to the trigger guard making light activation much easier for my hand size.
I'm currently bugging Surefire to sell the CAD drawing of the adapter to me for a reproduction run of them. They have not been responsive. Should they chose not to sell me the product, I'll reverse engineer it, change it by 10% and knock it off for the community. The gray market has driven pricing into the stratosphere, and I'd like to make this an affordable option again.
Thoughts?
