Just a few ...
1) I'd like to see a smaller, carry-friendly XD-45, along the lines of the XD 9mm ultracompact. However, I emailed the saies office at Springfield and got a very terse reply that they had no plans for such a pistol. (Their loss, toots.)
2) Smaller or no, I'd like an XD-45 with a decocker. I don't know if there's something inherent to the design of the gun that makes this impossible, but Eh, this is a thread where that doesn't much matter, right?
My P345 has a decocker, and so does my Browning BPM-D; decockers seem a good compromise to me between "cocked and locked, safety on" and "need to rack before firing." Seems harder to me to accidentally pull back a hammer than to deactivate most safeties. Heck, I'd like a decocker *and* an external safety.
3) Giving away my prejudices here, but I wish there was a P345 with a grip safety
That's one thing I really like in the XD, and something I admiire (for its foresight) in the Model 1911.
4) More models of *25 from S&W, i including a revived 3" barrel one, a 2" (c'mon! I know there are some police versions that have it!), and a Model 1,000,025 on the same movie-prop frame as the .500. Overkill, but no harm done
