I don't want to sound like a broken record. A pic is worth how many words?
$6 on Amazon and there are larger ones. The one I have is neoprene and stretches over the KT. Doesn't fly out of the biking jersey. No belly band chafing & sweating. No unmanly fannypack.
Oh, BTW - the NAA folding holsters are bulky and kills the concealability of that little revolver. If there is one thing I know fairly well, it's mouse guns and ways to stash 'em. I grew up in Chicago.
I have a NAA Mini revolver (2 actually) I am not a fan of the folding grips. I feel they slow it down. I found the neck holsters (that don't point at your head) to be one of the best ways to carry thee tiny guns.
