Expect to do some fitting. - SB Tactical SBT5K Pistol Stabilizing Brace for MP5K/SP89/SP5K

I installed this on an H&K SP5K. The bottom pin hole did not line up with the pin holes in the gun. It seemed like the pin hole in the stock was not straight but slightly angled.
I had to do a fair amount of filing of the stock pin hole to get the pin to line up and go all the way through. I used round files by hand because I didn't want to take off too much material using a Dremel etc.
I do like the brace, and it seems pretty solid now that it's installed.
Definitely disappointed that it did not fit an actual H&K without a bunch of messing around.
