Being that its two pieces i could try all sorts of things like a thumb lever you push down or the brass knuckle look you describe. I have been thinking how to make this work on a cocker with out it being mounted on the reg may still need the ccm grip frame because that's all i have to fit it to. ha ha smart parts better not with out paying up! I think in court this form would prove when and where the design came from who knows. Chadders posted the idea in April I found it last week. https://www.mcarterbrown.com/forums/c...on-sniper.html
If anyone wants to try to build one for personal use i have no problem with that and will try to answer any questions you may have.
