Does anybody know who makes the grip plug that Glockmeister brands (crookedly) and sells? I just bought one off eBay and though it no doubt came out of a box o' plugs, and though I hoped for the best even after seeing that the sample was stenciled crooked, the Glockmeister logo on the one I got was cockeyed on the plug. This only bothers those of us with OCD. : ) Anyway, I've seen a variety of styles of plug, and I want the style that GM sells, just without their crooked logo. Scherer? Pearce?
