Products

Gas Blowback

• Glock 19 Gen.4
• Glock 19 Third Generation
• Glock 17 Gen.4

Symptoms

If you hit the magazine hard while it is cocked, an unintended firing operation (hammer down) may occur.

• Slides and triggers may move forward without hammering down, but this is a structural specification.

Cause

This is because the internal parts are deformed by applying more force than expected when inserting the magazine.

• This is the cause that is known at this time.
• It occurs with parts dedicated to the target product.

We are currently conducting further investigations on the causes and countermeasures, so we will inform you about the details of this matter in the near future.

We sincerely apologize for any inconvenience caused to everyone who purchased the target product.

Customers who have the target product

As soon as the countermeasures are decided, we will provide free support, but in the meantime, please be careful not to give too much momentum when setting the magazine for the target products.

• Once the above symptoms occur, the symptoms are likely to reoccur even when the magazine is set with a weaker force than before.

About the possibility of symptom occurrence other than the target product

The symptom found with "Glock 19 Gen.4" this time is caused by the structure peculiar to the target product and occurs only in the target product.

• It is a structural specification that "slide advance" and "trigger position advance (in Glock model)" when the magazine is hit strongly with a product other than the target product. In this case, hammer down does not occur.
• If the same symptom (hammer down when the magazine is hit hard) occurs in other than the target product, there are other causes such as incorrect assembly of parts at the time of production and wear or damage of parts due to use beyond the endurance period.
• Please contact the 'Repair Inquiry Desk' at once.
