Realize that the BG 380 has a hard .75 inch grip for a reason...small means better concealment.
However, the thin backstrap in particular makes it a wiggly handgun to fire rapidly...as a person might have to do in a CCW situation.
Tried aftermarket grip sleeves and none of them would stay put, so cut three grip length pieces of old bike innertube and cut out mag release area to not interfere and installed.
Dramatically increased "gripability" while only adding a very small increase in grip width. Cost: zero.
Still working on other issues with this tiny titan but this one seems solved.
