These have been a "secret menu item" for ages. I cut 'em for the 1911, 9mm double stack and 45 double stack mags. Usually in Dark brown, black and that reddish chestnut brown (and I added tan this week). I can do fancy bright colours as well. (email me before ordering a bright one to see what I have on hand for bright or different coloured leather).
All these are cut to order, it usually takes me a day or so to get them on the bench.
I like using silicone gasket/caulk to hold them on, any of the spray glues or rubber cements will work fine as well.
These go out priority mail, yeah... I know, it's spendy for such a teensy item, but you get tracking and it'll be there in a couple of days!
