As an owner of many Grayguns SIG's, I can tell you that sending your HK to Bruce is money well spent. I've always wanted an HK and finally found the right one at the right time. My first opinion was that the gun strikes me as being well built and very reliable; however, the trigger left a LOT to be desired. I sent it to Bruce immediately and got it back last week--after only ten days, I might add.
Now, the gun is everything it should be.
A bit of advice though: I took a chance and did the "Competition Short Reset" instead of the RRCDP that I usually do with my personal defense guns...and I'm glad that I did. IN MY OPINION the CSR on the HK is much more like the RRCDP on the SIG Sauer. I have a Ti-Rant 45 on the way now...it'll make a righteous night stand gun.
