Duration: 12:15

This video provides an expert-level analysis of a modified PSA Dagger capable of full-auto fire, featuring insights from a knowledgeable firearms instructor. The host details the process of testing the firearm's performance under high rates of fire, including burst control, one-handed firing, and accuracy assessments. Crucially, the video highlights a common mechanical issue, 'pin walking,' observed after extensive use, and emphasizes strict adherence to legal compliance regarding NFA regulations for machine guns.

Quick Summary

The PSA Dagger, a 9mm Glock clone, was tested in full-auto mode using a 'Glock switch' modification. While surprisingly controllable for center mass grouping, it experienced 'pin walking' after ~200 rounds. Legal compliance with NFA regulations for machine guns is paramount, requiring FFL 07/SOT licensing for modifications.

Frequently Asked Questions

What is the PSA Dagger and what modification allows it to fire in full-auto?

The PSA Dagger is a 9mm pistol often described as a Glock clone. It can be modified to fire in full-auto using a device commonly referred to as a 'Glock switch,' which alters the firearm's trigger mechanism to enable automatic fire.

What mechanical issues were observed during the full-auto testing of the PSA Dagger?

After approximately 200 rounds of full-auto fire, the PSA Dagger exhibited 'pin walking,' where the locking block trigger pin began to protrude from the frame. This is a known issue that can occur due to the stress of high rates of fire on certain frame designs.

What are the legal implications of modifying a firearm for full-auto fire?

Modifying a firearm to fire automatically makes it a machine gun under federal law. Possession or manufacture of an unregistered machine gun is a felony. Such modifications must be performed by an FFL 07/SOT Class 2 holder, and the firearm must be registered with the ATF and have a tax stamp.

How did the PSA Dagger perform in terms of accuracy and control during full-auto testing?

Despite the challenges of full-auto fire, the PSA Dagger showed surprising controllability for center mass grouping on paper targets. However, one-handed full-auto firing proved difficult to keep on target at 10 yards due to significant recoil.
