The Swiss give us a super tiny PDW, the B&T TP9 / Steyr TMP

Duration: 16:28

The B&T TP9, an evolution of the Steyr TMP, is a compact PDW with a unique rotating barrel system. While offering extreme compactness for roles like vehicle work, it suffers from significant gas blowback, especially when suppressed, and a poor trigger. Its ergonomics are heavily right-hand biased, and iron sights are inadequate, necessitating an optic. Reliability issues with carbon buildup during suppressed full-auto fire require frequent maintenance.

Quick Summary

The B&T TP9, an evolution of the Steyr TMP, is a compact 9mm PDW. Its rotating barrel system offers extreme compactness but suffers from significant gas blowback, a poor trigger, and right-hand biased ergonomics. Reliability issues can arise with suppressed full-auto fire, necessitating frequent maintenance.

Frequently Asked Questions

What is the B&T TP9 known for?

The B&T TP9 is known for its extremely compact size, making it suitable as a Personal Defense Weapon (PDW) for roles like vehicle operations. It evolved from the Steyr TMP and features a unique rotating barrel operating system.

What are the main drawbacks of the B&T TP9?

Key drawbacks include significant gas and carbon blowback from the suppressor (especially for lefties), a poor trigger with heavy pull and long reset, and ergonomics heavily favoring right-handed shooters. Factory sights are also inadequate.

How reliable is the B&T TP9 when suppressed?

When used with a suppressor and in full-auto, the TP9 can seize up due to carbon buildup, requiring frequent maintenance. The speaker suggests maintenance every 300-400 rounds in such conditions.

What is the recommended setup for the B&T TP9?

A red dot optic mounted on a riser is highly recommended due to the poor quality of the factory iron sights. The integrated foregrip is standard, but accessory mounting requires consideration for the right-hand bias.
