Type 3 Malfunction: “Just Pull the Mag Out - Don’t Lock the Slide!” What aren’t you considering?

Published on November 10, 2024
Duration: 13:42

Instructor Mike details a method for clearing a Type 3 malfunction, often called a 'parking lot jam,' which occurs when a new round attempts to enter the chamber before the previous casing has been fully ejected. He emphasizes a 'lock, mag to pinky, rack three, mag in, rack' sequence, arguing it's more universally applicable than 'rip and rack' methods, especially on firearms with less aggressive magazine base plates. The instructor highlights the importance of context, noting that specialized techniques may not suit the average concealed carrier.

Quick Summary

Instructor Mike's method for clearing a Type 3 malfunction, or 'parking lot jam,' involves locking the slide back, placing the removed magazine on your pinky, racking the slide three times, reinserting the magazine, and racking the slide again. This technique is designed to be universally applicable, considering variations in firearm design and user capabilities.

Frequently Asked Questions

What is a Type 3 malfunction in a firearm?

A Type 3 malfunction, also known as a 'parking lot jam,' occurs when a new round attempts to enter the chamber before the previous casing has been fully ejected. This prevents the firearm's slide from going fully into battery, rendering it inoperable until cleared.

What is Instructor Mike's recommended method for clearing a Type 3 malfunction?

Instructor Mike advocates for a 'lock, mag to pinky, rack three, mag in, rack' sequence. This involves locking the slide back, removing the magazine and placing it on your pinky, cycling the slide multiple times, reinserting the magazine, and cycling the slide again.

Why is locking the slide important when clearing a Type 3 malfunction?

Locking the slide to the rear before clearing a Type 3 malfunction is crucial because it disengages the tension of the guide rod spring. This makes it significantly easier to cycle the slide and clear any obstructions without fighting against the spring's resistance.

How do magazine base plate designs affect malfunction clearance?

Magazine base plate designs significantly impact malfunction clearance. Smoother, less aggressive base plates offer less grip, making it harder to pull the magazine free against spring tension. Larger base plates with indentations, like on the CZ P10 F or Glock 19X, provide better purchase.
