I agree about the M&P45. Simply wonderful ergonomics. I can't speak to the XD, but I also own a XDm-45 Compact 3.8 which I like very much. I'm not prepared to swear that the M&P's ergonomics are hugely better between the two, but it has a slight edge although I like the XDm's very much. The M&P ergonomics are the most "1911-like" between the two, and that is high praise. The M&P trigger is better than the XDm's, but the XDm's is not terrible. It just has a slightly longer pull and reset than the M&P.A-R wrote:Put Smith & Wesson M&P45 on your short list as well. Better grip/ergonomic design than either XD or Glock, IMHO.
But, I gotta say the nay-no on the Glock 21. Even the SF version/Gen 4. I like the Glock 9mms, .40s, and 10mms OK, although they don't feel as good in the hand to me as an M&P or XDm. But the double stack .45 ACP Glocks are just too wide in the slide for me. It just isn't necessary to make a gun that humungous. It may be fine for a duty-carry piece where concealment isn't so much of an issue, but I have no use for a pistol with a slide so big that you could land a Cessna on the top of it. I'm left handed. A gun that big on my left hip, and I won't be able to close my car door. I already cast enough shade without adding a 4x6 on my hip.
I could go on.....

Seriously though, I had a chance recently to compare another forum member's G30 to my XDm. The G30 trigger was pretty good, and there is no doubt that the platform is reliable and rugged, but here we had two pistols aimed essentially the same market segment, having similar capacity, barrel length, performance, reliability etc., but the Glock had that aircraft carrier deck on top of the slide again. Held side by side, the XDm was in my opinion clearly superior as a concealment pistol. That said, this gentlemen used his G30 as his EDC and was very satisfied with it. But given a choice between the Glock and the XDm, I'd take the XDm. But that's just me.
