Haven't done much with it other than about 40 dry fires off the deck.Wow, really useful comparison, thanks for this. What is your impression so far?
It seems like the little hook shape under the tip is a little more useful for the way I normally run my bolt. I don't know what it's called but I tend to keep my hands on the right side of the grip (floating thumb) and just blade my pointer finger up and pull back kind of with the side of my hand and finger... That wasn't working well for me as I'd slip off the side but I had to learn to put my thumb on top of it and actually grab ahold to run the bolt. Seems like the little hook kind of lets me treat it like my other bolts.
It's not enough to make any leverage difference or anything like that from what I can tell
But again I'm only a few dry fires into using it, and I'm not any kind of a pro
