Frequently Asked Questions
Which specific Glock models is this extension compatible with?
The Pearce Plus Extension is designed for Glock mid and full-size pistols running high-capacity magazines. This generally includes popular models such as the Glock 17, 19, 22, 23, 31, 32, and similar variants. It replaces the factory floor plate and internal locking plate, so no additional tools or modifications are needed. Always verify your specific magazine model before ordering.
Does this extension affect the reliability or feeding of the magazine?
When properly installed, Pearce Grip extensions are engineered to maintain reliable feeding and function. The drop-in design is machined to Glock magazine tolerances, and the high-impact polymer construction ensures consistent performance. As with any aftermarket component, it is recommended to test the loaded magazine at the range before relying on it for defensive use.
Are there magazine capacity restrictions I should be aware of in California?
Yes. California law restricts the possession and use of magazines that hold more than 10 rounds. Depending on your firearm's caliber and original magazine capacity, adding rounds with this extension could place your magazine over the legal limit. Buyers in California should confirm their total loaded magazine capacity complies with current state law before purchasing or installing this product. Goodland Guns recommends consulting local regulations or a legal professional if you have any questions.
