ProMag PM089A Magazine Spacer Firearm Fit Glock 26/27 Compatible w/Glock 17/22 Magazines, Black Textured Polymer

The ProMag PM089A Magazine Spacer bridges the gap between your compact Glock 26/27 and full-size magazines, letting you use G17/22 mags with a proper fit. Whether you're shopping near Milpitas or anywhere in California, understand that California's 10-round magazine limit applies to all civilian magazine use. This spacer is a practical accessory for shooters who want magazine compatibility without compromising ergonomics.

How the spacer improves magazine fit

Magazine spacers solve a real problem: larger magazines rattle in compact frames. The PM089A's textured polymer construction grips securely while maintaining reliable feeding. When you're ready to purchase, our Sunnyvale FFL handles transfers for both local and out-of-state buyers. Check our FFL transfer pricing for current rates. This spacer works with 9mm Luger and .40 S&W magazines, making it versatile for dual-platform shooters. Visit our firearms dealer in Sunnyvale for our full catalog.

Frequently asked questions

Will this spacer work with aftermarket Glock 17 magazines?

The PM089A is designed for standard Glock 17/22 magazines. Compatibility with aftermarket brands depends on their dimensions. We recommend testing fit before relying on it for duty or carry use.

Does the spacer affect magazine spring tension or feeding?

No. The spacer is purely a fit adapter. It doesn't compress the spring or alter feed geometry. Magazine function remains unchanged—it simply fills the gap between the magazine and your compact frame.

What do I need to bring for DROS in California?
