HK USP Match
HK 91-94
M1 Garand (the SA ones don't count...)
Edited to add: Walther P99s. The original configurations, not the "New & Improved" ones. Maybe Glocks without finger ridges as well.
"The only criteria is that the manufacturer must still be in business and producing guns." If it weren't for that criterion, then everything the Germans made in WWII--Lugers, MP-40s, MG-42s, FG-42s, MG-34s, StG.44s, and so on...
