Hi, sorry, that was my dumb. I meant variant, not version;
USP
Standard, full-sized pistol. Sub-variants:
Variants 1 and 2
Has a decocking and safety lever. Can fire in both double- and single-action.
Variants 3 and 4
Same as Variants 1 and 2, but lacks the safety lever.
Variants 5 and 6
Has a safety lever. Fires in double-action only.
Variant 7
Double-action variant with no control lever.
Variant 8
Prototype variant that was never produced. Scarce information is available, but
one source states that is is just a Variant 7 with night sights.
Variants 9 and 10
Same as Variants 1 and 2, but lacks the decocking lever.
Law Enforcement Modification variant with Combat Defense Action trigger
A USP double-action only model with a unique trigger which reduces the weight of the trigger pull.
P.s. It was manufactured in 1994 (KE)
