Frequently Asked Questions

What makes the Makarov PB's recoil system unique?

The Makarov PB utilizes a unique recoil spring system housed within the grip. A lever connected to the slide actuates this spring, compensating for the space taken by the integral suppressor around the barrel, unlike the standard Makarov PM.

How is the Makarov PB's suppressor disassembled?

The Makarov PB's suppressor is a two-part integral system. The front section is removed by releasing a spring catch and rotating it. The rear housing is released by pulling down the trigger guard.

What is the sound reduction achieved by the Makarov PB?

Testing by Phil Dater indicates the Makarov PB averages 127.5 decibels, achieving a significant sound reduction of 31.4 dB compared to an unsuppressed Makarov pistol. It also exhibits minimal 'first round pop'.

What caliber does the Makarov PB fire and what are its ballistics?

The Makarov PB fires the 9x18mm Makarov cartridge. Its ported barrel vents gas to reduce the round's velocity to a subsonic 950 fps, preventing a sonic crack and contributing to its suppressed performance.
