X-CATCH FX Steel Release Lets Glock 48 Owners Mix 15-Round Mags

Plenty of hunters and hikers carry a Glock 43X or 48 as a slim sidearm in the field, and the arrival of Glock’s factory 15-round magazines this year gave those pistols more capacity without a trip to the aftermarket. The complication comes when the same owner also keeps Shield Arms S15 magazines around. Steel S15s wear down polymer and aluminum releases, while XTech Tactical says existing steel releases won’t accept Glock’s wider 15-round magazine at all, and a forced one locks in the pistol. XTech’s new X-CATCH FX is a machined-steel, extended release built to handle both. For anyone who shuffles magazines between a hunting-season chest rig and a daily carry setup, it removes a compatibility question before it turns into a stuck magazine.

Anyone who has fumbled a mag release with cold fingers or gloves during a late-season hunt can picture where a larger working surface helps. The X-CATCH FX is reversible for left-handed shooters, installs with the factory spring, and fits all 43X and 48 variations. Being machined steel, it also avoids the molding warp XTech blames for inconsistent drop-free performance with factory parts. MSRP is $39.95 with a lifetime warranty, and it is available now from XTech and through authorized dealers. The company says its own 43X/48 magazines are coming next, and Deadman wants owners putting them up against everything else on the market.

A machined-steel, extended release ends the forced choice between Glock’s new 15-round magazine and steel aftermarket magazines

GILBERT, AZ

Nov. 3, 2026

 XTech Tactical today launched X-CATCH FX, an all-steel, extended magazine release for the Glock 43X and 48. It is the only steel release engineered to run both Glock OEM 15-round and Shield Arms S15 magazines in the same pistol.

The problem

• Steel magazines like the Shield Arms S15 wear down polymer and aluminum releases.
• Existing steel releases won’t accept Glock’s wider 15-round magazine. Forced in, it locks in the pistol.
• Glock’s stamped-steel 15-round magazine is about .020″ wider than its polymer 10-round, and its formed dimple varies from mag to mag. Paired with a warped, injection-molded factory release, drop-free is inconsistent.

The X-CATCH FX solution

• Machined steel, so no molding warp; made in USA
• Dimensioned for the full width range of Glock OEM 15-round and Shield Arms S15 magazines
• Proprietary beveled, tumbled engagement face reduces wear on polymer magazines
• Extended button releases from anywhere on its face; the factory release works only from its front edge
• Reversible for left- or right-handed shooters; installs with the factory spring
• Fits all Glock 43X and 48 variations
• Also accepts Glock OEM 10-round and PSA 15-round magazines (not recommended for primary use)

“43X and 48 owners have lived through patent fights, baseplate failures and feeding complaints across brands. They’ve earned the right to run whatever magazine proves itself in their gun, without continually modifying their pistol,” said Jeremy Deadman, Founder and Managing Member of XTech Tactical. “What looks like a simple part took hundreds of hours of engineering and iteration. With this much variance on such a small surface, it’s like threading a needle. Our own magazines for this platform are coming next, and when they do, we want people dropping them, beating on them and comparing them to everything else. X-CATCH FX means you can run them all and let the results decide.”
