Try a search on the P345, there have been other threads recently.
Its my favorite range gun, and is becoming my favorite carry as well. It is flat like a 1911 and except for the longer barrel, carries better than my PX4 Sub Compact. I only have 200-300 rounds through it, but they have been flawless through a mix of "whateverisonsale" and Win. Ranger +p.
I've rented 45's from HK to Kimber to Glock and XD, and for $400 there cannot be a better .45 out there imho. It is relatively small and lightweight compared to XD or FN especially, with very manageable recoil.
I also really like the trigger. I find that the DA pulls smooth and can be staged or pulled through with ease. For range work this is really nice.
Downside #1: Although I certainly like the thin-ish grip I actually don't care for the feel. But, added the Pachmyer and its perfect. I recommend not getting a full-size rubber grip. I find that sliding my thumb between the rubber on the grip and the holster causes my thumb to hang up if that part of the grip is covered with rubber. This particular rubber "glove" is for the XD.
Downside #2: I think whoever designed the take down process is a masochist. You need three hands. I'm still trying to work out a system. Compared to a PX4 it is medieval.
