Key Features

Threaded Barrel

The factory threaded barrel provides immediate compatibility with muzzle devices or suppressors where legal and practical. For users who plan to add a compensator or suppressor-ready setup, having a threaded barrel from the start reduces the need for gunsmithing.

17 Round Magazines

Equipped with 17 rnd mags, the SDP COMPACT balances capacity with concealability. The higher-capacity magazines extend endurance between reloads while maintaining a compact grip footprint suitable for defensive carry or duty rigs.

Finish and Condition

The Matte Green finish is both practical and distinctive—resistant to reflections and durable under routine carry. The listing’s NEW / Old stock designation suggests these pistols are unused but from prior production runs; inspect the product page for exact condition notes before purchase.
