Hi! I'm looking for a Glock 19 gen 3 or 4 frame or an aftermarket equivalent. Also I'd be interested to know if any local San Antonio gun shop stocks such a thing that I can just walk in and buy. I can order an SCT from Brownels for about $100 with transfer, so I'm not looking to spend a lot. But a little more wouldn't kill me for the convenience of buying local. Thanks for your emails, I look forward to your responses.
