This expert guide details the maintenance requirements for the B&T TP9 when used with a suppressor, particularly during suppressed full-auto fire. The video highlights that carbon buildup can cause the weapon to seize after approximately 13 magazines, necessitating cleaning every 300-400 rounds. It also covers ergonomic considerations, sight recommendations, and the trigger's performance.

Quick Summary

The B&T TP9, a compact PDW evolved from the Steyr TMP, offers extreme portability but has notable drawbacks. Suppressed full-auto fire requires frequent cleaning (every 300-400 rounds) to prevent seizing due to carbon buildup. Ergonomics favor right-handed shooters, and the factory sights are poor, necessitating an optic. The trigger is heavy and has a long reset.

Frequently Asked Questions

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

The primary drawbacks include significant gas and carbon blowback, especially for left-handed shooters, which can impair visibility. Additionally, suppressed full-auto fire necessitates frequent cleaning to prevent the weapon from seizing due to carbon buildup, typically every 300-400 rounds.

How is the trigger performance on the B&T TP9?

The trigger is widely considered a weak point, featuring a heavy pull weight of 8-9 pounds and a long reset. This has led some professionals to leave the weapon in select-fire mode and rely on the trigger's safety mechanism.

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

The B&T TP9 excels as a purpose-driven Personal Defense Weapon (PDW), particularly for vehicle operations or close protection duties, due to its extremely compact size and maneuverability.

What are the ergonomic and sighting considerations for the B&T TP9?

The firearm is heavily biased towards right-handed users, with limited rail space for accessories on the left. The factory iron sights are uncomfortable, making a red dot optic on a riser highly recommended for effective use.
