The only NIB USP Compacts I have ever seen, except for several I'll describe in a minute, that have come from HK/USA have all been V1 versions... DA/SA with a manual safety/decock lever on the left side of the frame. Supposedly, one can have a pistol ordered through HK/USA in any variation. I've never heard of anyone that was successful with this. Everybody I am aware of first bought a V1, then either sent it back to HK/USA for conversion, had somebody do it, or did it themselves.
Back about 15 years ago, when the government was setting up the Federal Flight Deck Officer (armed commercial airliner and transport pilots) program, the USP Compact was selected for their issue pistol... but the caliber was still open to debate. HK sent several hundred 9mm, .40 S&W, and .45ACP USPc's to the government agency doing the testing, and the .40 S&W was selected. The remaining 9mm and .45 pistols were sold to a vendor and re-sold to citizens like me; I bought a .45. All of these pistols were LEMs. Also, for some years, HK/USA would sell a factory LEM USPc .40, with night sights and three magazines, to anyone who could show a valid commercial airline or transport pilot ticket. The price was great... $500 bucks.
Here's the deal... the easiest way to tell if a USPc LEM pistol is a valid factory-built LEM, is that the safety lever marks on both sides of the frame do not have the white paint in them. Of course, you have guys like me who have removed those marks on V1s That we put LEM kits into... so that's not always a good indicator.:wink:
