Description
This ProMag magazine slides right into any Browning Buck Mark pistol chambered in .22 LR and holds a full 10 rounds of ammunition. It's built from heat-treated carbon steel with a blued finish, so you're getting real durability in a no-frills package. The magazine uses an injection-molded follower and a spring made from heat-treated chrome-silicone wire, both engineered to feed rounds consistently through your rimfire pistol.
Built for the Range and Field Work
ProMag designed this mag specifically for Buck Mark owners who need extras without breaking the bank. Whether you're doing a range session and want to minimize reload time or keeping a spare in your gear bag, this 10-rounder does the job. The oversized loading button makes it easier on your fingers when you're stuffing rounds in during a long shooting day. The magazine body is constructed with the same heat-treating process ProMag uses across their steel magazine line, which means it'll stand up to years of range use.
A Straight Replacement That Works
Fits the modern Buck Mark platform perfectly, and the 10-round capacity is the standard for this pistol. Some users report that new magazines have stiffer springs straight out of the box, which is normal and will loosen up with use. The polymerfollower keeps things running smooth, and the chrome-silicone spring maintains consistent feeding without the spring pack taking up too much room inside the magazine body.
ProMag backs this magazine with a lifetime warranty against manufacturer defects, so if something goes wrong, you've got recourse. Made in the USA by a manufacturer that's been in the magazine business since 1986.

Frequently Asked Questions
Will this ProMag magazine fit my Browning Buck Mark?
Yes, this magazine is specifically designed for all modern Browning Buck Mark pistols chambered in .22 LR. It uses the same detachable box-magazine system as your factory magazines and seats the same way. If you have a modern Buck Mark from the early 1990s onward, this will work.
Why is my new magazine hard to load?
ProMag magazines come with stiffer springs out of the box, which is normal and actually helps with long-term reliability. After you load it a few times or put a few range sessions through it, the spring will break in and loading becomes easier. This is not a defect.
How does this ProMag compare to the factory Browning magazine?
ProMag magazines are aftermarket alternatives that provide the same 10-round capacity and basic functionality as Browning factory magazines, but at a lower price point. Some users report the fit can be slightly tighter on the mag disconnect than factory mags, so minor adjustment may occasionally be needed. Both work for range and practice shooting.
What's covered by ProMag's lifetime warranty?
ProMag's lifetime warranty covers defects in materials and workmanship. If the magazine fails to feed reliably due to a manufacturing issue, ProMag will replace it free of charge. The warranty is against manufacturer defects, not damage from misuse or modifications.
