You've got me confused now :lol:

I thought I had it all figured out

From what I gather from this, is that the USG has a slimmer slide (pg 9). Apparently, they are making regular ones with manual safeties, but not considering them USG versions because they don't have the slim slide. That's my best guess as to the difference (also the front serrations on the slide).

Edit: I also just noticed the USG is 0.8 ounces lighter.

I dont think the slide is really slimmer but a bit more rounded at the top instead of flat like the normal 45, Sorry if I added to any confusion

The catalog says that the USG has a "Slim-slide," whatever that means is open to interpretation, or if someone has both/has personal knowledge, now is the time for input :?
