Published on December 5, 2019
Duration: 20:56

The B&T APC9-SD offers a Swiss-engineered solution to suppress standard 9mm ammunition using an integral suppressor and ported barrel, similar to the HK MP5-SD concept. Chronograph tests confirm it slows supersonic rounds to subsonic speeds, allowing for maximum suppression without specialized ammo. Despite its high cost, the APC9-SD delivers exceptional quality and performance.

Quick Summary

The B&T APC9-SD achieves subsonic suppression of standard 9mm ammunition via an integral suppressor and a ported barrel. This system bleeds off gases near the chamber, slowing bullets to subsonic speeds without requiring specialized ammo, offering high Swiss quality and cost-effective shooting.

Frequently Asked Questions

How does the B&T APC9-SD make supersonic ammunition subsonic?

The APC9-SD uses a unique integral suppressor combined with a ported barrel. Numerous small holes just ahead of the chamber bleed propellant gases into the suppressor, slowing the bullet down to subsonic speeds before it exits the barrel.

What are the main advantages of the B&T APC9-SD?

Its primary advantage is the ability to effectively suppress standard supersonic 9mm ammunition using its integral suppressor and ported barrel system, eliminating the need for expensive subsonic rounds while maintaining high Swiss quality.

Does the B&T APC9-SD require special ammunition?

No, unlike many suppressed firearms, the APC9-SD is specifically designed to slow down regular supersonic 9mm ammunition (like 115gr and 124gr ball) to subsonic velocities using its ported barrel and integral suppressor.

What is the cost and quality of the B&T APC9-SD?

The APC9-SD is considered expensive, with an MSRP around $3300 including the silencer. However, it is highly praised for its exceptional Swiss engineering, build quality, and innovative suppression system.
