The Spectre Comp Blackout series features a factory compensator with the green-dot front sight mounted directly to the comp. This setup keeps the front sight fixed relative to the muzzle device and is paired with a two-dot rear sight at the rear of the slide.
The Custom Works slide is optics-ready with a removable cover plate. It carries long top lightening windows and aggressive front and rear serrations, with a black finish and the CUSTOM WORKS marking. The chamber hood is marked “9mm x 19” and “1/2-28.”
The 4.6 in steel barrel is threaded 1/2x28. A full-length M1913 Picatinny accessory rail runs along the dust cover for mounting lights or lasers as desired.
The XSeries TXG grip module (tungsten-infused polymer) wears the LXG laser-engraved texture for a planted hold, and a flared magazine well is installed to speed reloads. The flat, skeletonized trigger complements the striker-fired action for a consistent press.
Capacity is 21+1 rounds with the included steel magazines, each stamped “MADE IN ITALY” and numbered to 21. Proof and origin markings read “NEWINGTON, NH, USA, MADE IN UNITED STATES.” Manufacturer part number is P320V004.
