I do not know how they will hold up with wear or weather. I am shooting with them tonight.
Neat idea cico, pretty wild looking grips!
On holding up? May depend on if and how the leather is used, treated or with what?
And, not really much different than a set of leather gloves if thought about?
Just thoughts is all. The leather thickness and type, the moisture may prove awkward later on depending on treatment. With normal body sweat or perspiration is one thing, in rain or wet weather could be another? Wet leather can be very soft, slippery and malleable almost like squishy mud in a hand. Could lead to grip issues if not careful. May need to stabilize leather with something to keep it more rigid and firm if hasn't been done already. - A plasticizer of some sort?
Leather also may interfere with mag release and mag insertion too when and if too soft depending on firearm when using for grips. A thin stiff plate between grip and gun may help? Rigid grips are usually best, although there are softer rubber grips available, rubber grips are usually hard rubber though because of possible slipperiness. Good luck on your test trial!
