jcb is right........you don't want to drop the $$ only to find out that your new pistol is not approved for your job.

That said, most departments I think recognize Glock, and they make some of the simplest, and most reliable ones out there. I forget which model is their .45? I know the sub is the mod30 but I don't know what the service model is?

If money is no object and they are Ok for your use, Kimber is about as good as it gets for a factory .45 1911 style pistol. PRobably any of their 4" Pro frame models would fit the bill nicely.

If you are willing to look outside the .45 to say a .40 I can personally vouch for the Springfield XD .40 service. I have about 1000 rounds through mine and use it for home defense and carry and it has performed flawlessly and is quite accurate. No goofy safeties, cocking and loaded chamber indicators as well if you find yourself in complete darkness wondering if your locked and loaded.
