Based on the functional lines of the USP, the USP Match is designed
and manufactured to achieve top class accuracy. The USP Match
pistol approaches the precision found on the Mark 23 by adding a
special barrel weight system, extended target barrel, adjustable
trigger, and target sights to the USP .45 ACP.
USP Match pistols use the same patented recoil reduction system
found on the full-frame USP and the Mark 23. When the pistol is
fired, the impulse of the reaward-traveling barrel and slide are
effectively buffered, eliminating the direct transmission of recoil
forces to the pistol's frame and the shooter's hand.
An innovative design feature found on both the Mark 23 and the
USP Match pistol is a high-temperature rubber O-ring that seals
and centers the barrel in the slide until the barrel is unlocked by
the slide's rearward movement. The O-ring has a significant effect
on accuracy, lasts more than 20,000 rounds, and can be replaced
without tools in seconds.
