Another curiosity in the USP series: While most variations have the classic squared-off slide with a lightening cut from the ejection port forward, the Elite is unique in that the entire slide is angled and much narrower at the top than the other variants, and of course it has the smaller front end. Probably a design necessity, with the 6.02-inch barrel it would have added a bit of slide weight over the Expert without that design mod. Frame is the same on all full size 45 variants, although the trigger and decocker are different on the non-standard models they can be swapped as desired.
The Expert and Elite 45's are both long-slide variants, 5.20 and 6.02 inch barrels respectively, with match triggers and adjustable sights. Both are intended more for target and gaming use and not so much for carry.
