I have room in my current collection for a single, full-size handgun. Right now, that position is being filled by a Glock 19, but I am ready to move up by selling the G19 and buying something else. First, I have decided that a full-size handgun--if I only have ONE--should probably be in .45 ACP. We could have the tired caliber argument, but we all know this comes down to personal preference at some level, so .45 ACP is my decision. My need for this pistol fits under the category of in-home personal defense and SHTF protection of my area (family, home, community, whatever I need to protect). My thought is that all things being equal I would love to have as many rounds as possible. But not all things are equal. Part of me really wants a SA XDm45. 13+1. Part of me knows that if I only have room for one full-size, then why not go with a 1911A1? But Browning designed it to be 7+1. Question: Do the benefits of the 1911A1 design balance the "lower" capacity?
