I went thru 3 lok grip palm swells and finally settled on the thin lok grips. The palm swells felt better when holding the gun 1 handed, but using a 2 handed grip, I like the thins because it felt like a more secure grip. I just prefer the support hand to be gripping a flat surface. Tried mayhem, grenade, crosscut, and finally settled on the full checkered.
The mayhem dug into my fingers when I grip tight, the grenade and crosscut were comfortable but the grip wasn’t as secure. The full checkered sandpaper-like texture gives secure grip without digging into my fingers. It’s not as comfortable against the skin for appendix as the grenade and crosscut, but it’s a good compromise. Lok grips have a good return policy so you can just order a few and send back the ones you don’t like.
