Extar Firearms has redesigned its EP9 and EP45 large-format pistols around a roller-delayed blowback operating system, with The Firearm Blog reporting the full reveal on July 1 following the company's showcase at GunCon 2026 in Niles, Ohio. The new variants, designated the EP9 MDB and EP45 MDB for Modern Delayed Blowback, retain the platform's defining traits — Glock magazine compatibility, AR-style controls, and direct-to-consumer pricing — while replacing the original direct blowback cycle with a mechanically refined operating system.

The upgrade represents the most significant mechanical change Extar has made to either platform since the EP9's introduction. In a direct blowback pistol-caliber design, the bolt cycles using spring resistance alone against the rearward gas pressure of the fired cartridge, producing a snappier recoil impulse than a delayed or locked-breech system. Roller-delayed blowback inserts a pair of rotating rollers into the bolt assembly that mechanically brace the bolt against the trunnion during the highest-pressure moment of the firing cycle. Once chamber pressure drops to a safe level, the rollers cam inward and the bolt travels rearward. The practical result is a smoother recoil impulse, reduced bolt velocity at extraction, and generally cleaner case ejection.

The EP9 MDB is chambered in 9x19mm and weighs 3.75 pounds. The EP45 MDB handles .45 ACP and comes in at 4.35 pounds. Both models preserve the M-LOK handguards, threaded barrels, and Glock-pattern magazine wells that built the original EP9 a following among shooters looking for an affordable pistol-caliber platform. AR-style controls — bolt catch, mag release, pistol grip angle — carry over unchanged, keeping the manual of arms familiar to anyone who has run an AR-15.

Extar built its reputation around direct-to-consumer sales, stripping out the distributor and dealer margin chain to keep prices well below the typical AR-pattern PCC. The original EP9 has sat in the $449–$469 range through Extar's own web store. Specific pricing for the MDB variants has not been announced, though the company has indicated it will maintain the same direct-to-consumer model. Given that roller-delayed actions carry higher manufacturing costs than simple direct blowback, some price increase from the original is likely.

The timing aligns with strong market tailwinds. The elimination of the $200 NFA transfer tax on suppressors earlier this year has driven a surge in suppressor purchases and, alongside it, demand for suppressor-optimized hosts. The EP9 and EP45's threaded barrels and closed-bolt pistol-caliber designs have always made them solid suppressor hosts, and the smoother cycling of the roller-delayed action reinforces that pairing. Subsonic 9mm and .45 ACP are inherently quiet through a can, and a host with reduced bolt reciprocation energy runs even cleaner in suppressed configurations.

Extar has not confirmed a ship date for the MDB models. Pricing and availability details are expected through the company's direct ordering portal at extarusa.com. Buyers who already own earlier EP9 or EP45 variants will want to confirm parts interchangeability before the MDB rolls out, as the roller-delayed bolt group represents a substantive departure from the original direct blowback assembly.
