I can think of one way by bracing the grip between your knees, but I wasnt to try it on my Witness before I espouse it's efficacy. My 10mm has a 22# Wolff spring in it. If it works on that, it'll work on almost anything.

I wasn’t aware of that feature. Somewhere I have a .22 High Standard H-D Military Model. I don’t recall it doing that. I’ll have to dig it out and see whether it does or not.
