High quality thumbrest.
Doesn't fit standard box.
Needs a little gunsmithing like anyother aftermarket gun part

Disappointed, while it seems like a solid product, it will not mount directly to the frame. I was looking for something for Limited/Limited Optics in USPSA.

Boss Components recommends 15-inch lbs of torque and a drip of blue Loctite on mounting screws. Use caution when installing screws, as over-tightening can damage the frame. Please note mounting screws are not included. The use of a certified gunsmith is always recommended.
