Frequently Asked Questions
Will this sleeve work with any Glock 29 magazine or only specific ones?
The Pachmayr Magazine Sleeve is designed specifically to fit Glock 21 full-size magazines for use in the Glock 29. It is not intended for use with standard Glock 29 flush-fit magazines. Always verify compatibility with your specific magazine generation before purchasing.
Does installing this sleeve permanently modify my magazine?
No — the Pachmayr Mag Sleeve simply slides over the body of the full-size magazine and holds securely in place without any permanent alteration. You can remove and reuse the sleeve whenever you choose, and your original magazine remains unmodified.
Can I still use my Glock 29 for concealed carry with this sleeve installed?
The sleeve is designed to be used when additional grip size and capacity are desired — such as at the range or in a home-defense role. For concealed carry, most users prefer a standard flush-fit magazine for a more compact profile, then swap to the full-size magazine with sleeve when appropriate. Note: California residents should ensure their magazine capacity complies with all applicable state regulations.
