Real-life attachment that gives +1 ergo - Strike Industries Bang Band Mini

I absolutely love these things and I've got them on all of my favorite guns. Very simple, tough rubber bands with an indexing "bump" that'll provide extra surface area to perfectly align your fingers where you want them.

It's actually insane how much more comfortable and stable my CCW got after attaching this (P365 XL), as it gives far more surface area for my fingers to tightly grip it, and since it's literally just a rubber band, it's very easy to adjust without losing its position during use.

I also stick them on pistol grips for rifles, vertical/angled grips, and even on the grip of my SGA stock. It's subtle enough but still retain enough presence to act as an indexing point, in place of a full-blown hand stop.

I tend to pick up a pack every time I make larger purchases since there's always SOMEWHERE I can add these, and having different color options is nice too.
