Don't want to stray from the topic at hand, but when you say a "UMP on letterhead" I'm guessing you either meant USC or that you're department is going to purchase a UMP for you, to issue to you, and thus remain department, not your, property. Correct me if I'm wrong, (and I'm not), but you can't purchase a UMP or any other weapon of that "type" on individual officer letterhead. To do otherwise would seriously raise the ire of those who regulate said activity, not to mention post-deadly force related court issues. If we could I'd be the first in line. I'm an ardent supporter of LEO letterhead sales of ALL applicable, (and LEGAL) weapons, including pistols, rifles, and shotguns or whatever your department allows. If you take advantage of the opportunity they give you, it gives you a better leg to stand on when the politics comes into play and they decide they no longer want to subsidise, (through letterhead price advantages), or otherwise allow you to carry, what those you protect and serve may not be able to legally own. Sounds like I'm starting another topic, I'll stop now...
