So I am looking to get back into a .45 ACP. I had a few 1911's and a S&W 645 long ago but I miss shooting that big old round. So I am torn now between a Glock 21 or a XD 4″ Full Size .45ACP. I can get a military discount on either one. I already have a Glock 19 so I am familiar with the brand. But to be honest, I am not a fan of the Glock triggers.
