Additionally, the Px4 has been announced in .45 ACP designated as the Px4 Storm SD (Special Duty). Notable differences between the standard Px4 and the Special Duty are the desert tan frame color, PVD coated magazines and internal firing control assembly, double recoil spring, specially roll marked slide and a longer barrel to facilitate the use of a suppressor. The PVD coated magazines (one ( and two 10 rounds mags come with the package) are not scheduled to be imported and there will only be one production run of the PX4SD. Supplies are limited. Initial photos show the barrel with a silver proprietary coating but the production models have a black finished barrel. Also, pistol tags indicate that superluminova sight paint is standard but Beretta USA discontinued use of the paint in 2009 so the PX4SD will have standard white 3-dot sights. The special Pelican case contains oil, cleaning kit, 3 mags, pistol, all 3 back straps, all 3 mag buttons, manual, warranty card and 2 foam dividers.

Prices for this pistol are ranging from $750-$1200 new.
