H&K USP owners, does a Streamlight TLR-1 fit??

[DeltaCharlie2]

I just bought a full-sized USP 9mm, but can't seem to get my Streamlight TLR-1 light to fit on the accessory rail.

Am I just not trying hard enough, or does this light not really fit?

Thanks

You need an H&K key.

To expound on that, USPs have their own proprietary rail...you'll need to get a rail adapter that will attach to the HK rail and then give you a pic rail underneath.

Here's one example: GG&G Adapters for HK USP

Thanks. I ordered the Promag adapter from MidwayUSA.com.
