Shield Arms Handgun Magazine Extension +5/+4 for Glock 19/23 Black

The Shield Arms Handgun Magazine Extension +5/+4 for Glock 19/23 in Black is designed to enhance the magazine capacity of your standard OEM magazines. This extension allows Glock 19 9mm magazines to hold a total of 15 rounds (10+5) and Glock 23 .40 S&W magazines to hold a total of 14 rounds (10+4), making it a practical solution for operators, competitive shooters, and duty personnel seeking extended capacity.

The extension features an easy-access floor plate design that facilitates rapid field maintenance and cleaning without removing the extension from the magazine body. This design approach streamlines access to the spring and follower during routine service intervals, which is critical for operators who maintain magazine integrity during frequent training cycles or extended duty rotations. The product includes Shield Arms' proprietary spring and is backed by a lifetime warranty.

Glock 19 and Glock 23 users, particularly those involved in competitive shooting, law enforcement training, or civilian self-defense, will find this extension beneficial for increasing magazine capacity without the need to purchase entirely new magazines. The black finish integrates seamlessly with standard Glock duty and training configurations. Please verify your local laws regarding magazine capacity enhancements before purchase.
