Auto sear: Get your stainless auto sear 

Auto sear, often referred to as Machine Gun Conversion Devices (MCDs), are aftermarket components that transform standard semi-automatic firearms into fully automatic weapons. Specifically, a standard firearm requires a distinct trigger pull for every shot fired, an MCD fires the weapon to fire continuously while the shooter holds the trigger down. This modification of auto sear enables a handgun to deplete an entire magazine in just a few seconds, effectively turning it into a machine gun.

A Glock switch, also referred to as an auto sear, glock with a switch refers to a small device linked to Glock pistols that changes the way the firearm functions. Furthermore, although it appears minor in size, its impact on the weapon’s firing operation is substantial. Consequently, due to the effect it has on how the firearm behaves, it is not legally classified the same way as ordinary firearm accessories and is subject to stricter regulation.

Key Technical Breakdown:

Mechanical Function: It disables the semi-automatic disconnector, allowing the firing pin to strike each subsequent round automatically as the slide closes.

Firing Rate: It can enable a pistol to fire at a rate exceeding 1,100 rounds per minute.

Legal Status: In the United States, these devices are classified as “machine guns” under the National Firearms Act (NFA).

Advantages of using a Glock Switch on your Firearm

1. Extreme Rate of Fire
The primary mechanical change is the shift from semi-automatic to fully automatic fire. A standard Glock typically fires as fast as a human can pull the trigger (roughly 60–100 rounds per minute). Nevertheless, with a switch, the firing rate increases to approximately 1,100 to 1,200 rounds per minute.
• Result: This allows a shooter to suppress a target or put a massive volume of lead downrange in a matter of seconds.

2. Force Multiplication
In a tactical sense, a switch turns a concealable handgun into a “submachine gun” equivalent in terms of output. This provides a massive amount of firepower in a very small package, which is why these devices are technically categorized as machine guns.

3. Psychological Effect
In combat or high-stress environments, fully automatic fire creates a “suppressive” effect. The rapid sound and volume of fire can force an opponent to stay behind cover, allowing the shooter to maneuver or escape.

How to install a Glock Switch: Full Guideline

The installation of a conversion device—commonly referred to as a “switch”—involves modifying the fire control group of a striker-fired pistol to enable automatic fire. However, this process bypasses the weapon’s internal safety disconnects.
Technical Integration Steps:

1. Clearance and Safety: The operator must verify that the weapon is completely clear of ammunition and that the chamber is empty.

2. Field Stripping: The slide assembly is removed from the receiver to access the internal trigger mechanism.

3. Backplate Replacement: The standard slide cover plate is replaced with the conversion device. Furthermore,this device features a physical protrusion designed to interact with the trigger bar.

4. Mechanical Alignment: The device must be seated so that it forces the trigger bar down when the slide returns to the “in-battery” position, triggering a continuous cycle.

5. Operational Verification: A dry-fire function check is performed to ensure the striker releases as intended.

Safety Rules in using a Glock switch 

1. Treat every firearm as if it were loaded.

Always assume the weapon is hot. In addition, even if you just watched someone clear it, you must personally verify the status of the chamber every time you take control of the weapon.

2. Never point the muzzle at anything you are not willing to destroy.

This is “muzzle discipline.” If the firearm were to discharge accidentally, the round should impact a safe direction (like a berm or the floor) where no person or valuable property will be harmed.

3. Keep your finger off the trigger until your sights are on the target and you have made the decision to fire.
This is “trigger discipline.” In addition, the trigger guard is a “no-fly zone.” Your index finger should remain straight and indexed along the frame or slide until the moment of engagement.

4. Be sure of your target and what is beyond it.
Bullets can travel through walls, wood, and metal. However, you are legally and morally responsible for every round that leaves your barrel. Therefore, you must ensure there are no bystanders or hazards behind your target.

Frequently Asked Questions

1. What is a “Glock Switch”?

A Glock switch is an aftermarket rear slide plate modification. It functions by overriding the pistol’s internal disconnector. By protruding into the path of the trigger bar, it forces the bar to drop as the slide returns to battery, resulting in continuous automatic fire.

2. How does the mechanical cycle work?

Specifically, unlike a “bump fire” system, these switches use a physical sear trip. As the slide cycles forward, the switch strikes the trigger bar, releasing the striker immediately. Accordingly, this cycle repeats automatically as long as the trigger remains depressed, achieving a cyclic rate of approximately 1,200 rounds per minute.

3. What is a Drop-In Auto Sear (DIAS)?

Regarding the DIAS, manufacturers design the DIAS component specifically for AR-pattern receivers. It is part of the fire control group and interacts with a full-auto bolt carrier. Furthermore, when the bolt carrier moves forward, it trips the DIAS, which in turn releases the hammer to strike the firing pin without a secondary trigger pull.

4. Do you ship discreetly?

Yes. Furthermore, every order is packed in plain, unmarked boxes without logos or product names. In addition, we ship express and securely across supported regions.

5. Are these devices compatible with “Ghost Guns” (P80)?

Moreover, because Polymer 80 and other “80%” frames replicate Original Equipment Manufacturer (OEM) Glock specifications, they remain mechanically susceptible to the same conversion devices as factory-produced firearms.

6. What are the legal requirements for acquisition?

We do not require any documents or paper for you to browse or shop with our online store.

7. Do you ship worldwide?

Yes. We ship worldwide, ensuring discreet plain packaging, fast and reliable service that helps you keep track of your package.
