The FAB Defense OPMOD 4 Round Magazine Extension For Glock 43 is an aftermarket accessory designed to enhance the capacity of the Glock 43, a popular compact and subcompact 9mm pistol. Glock pistols are known for their reliability and widespread use among law enforcement, military, and civilian shooters, and various accessories are available to customize and optimize their performance.

The magazine extension is designed for easy installation and does not require special tools or gunsmithing skills. It can often be attached to the magazine without any permanent modifications to the firearm.

FAB Defense is known for producing high-quality firearm accessories, and this magazine extension is typically made from durable materials such as polymer or reinforced nylon, ensuring that it can withstand the rigors of regular use.
