Standard S15 Mag Catch for Glock® 43X / 48
Our ambi steel mag catch/mag release for the Glock® 43X & Glock® 48.




Why Upgrade to a Steel Mag Catch
A Glock plastic OEM catch will experience increased wear and tear with prolonged use when used together with any steel magazine.
Our patented Shield Arms S15 15-Round Magazines were designed to work best with our Standard or Premium S15 Steel Mag Catch for Glock® 43X / 48.
The Shield Arms S15 Magazine coupled with our well-crafted steel catches deliver 150% OEM mag capacity with greater dependability again & again.

- PEACOCK BLUE: This is an iridescent shade of multiple colors, primarily blue. Please know color will vary slightly per unit.
- DLC: Diamond like Coating - Wear and abrasion resistant; surface comparable to natural diamond. It's high lubricity reduces friction between sliding surfaces and it is chemically non-reactive.
Considerations & Recommendations:
- Shield Arms S15 magazines are constructed using steel vs. Glock's standard plastic OEM mags.
- Shield Arms S15 magazines provide 150% capacity over the Glock® OEM mags for the Glock® 43X/48 .
- More round capacity equals more total round mass supported by the mag catch.
- If you don't swap your mag catch you may experience reliability issues.
- Using another manufacturer's mag catch may also cause reliability issues.
Conversely: - While it remains generally compatible with plastic OEM magazines, it can cause increased wear on plastic mags with prolonged use.
- We do not recommend using our steel mag catch with plastic OEM mags as OEM mags may not drop free.
Bottom Line:
We ALWAYS recommend steel on steel or plastic on plastic, and our own steel mag catches engineered specifically for our S15 15-round mags for the G43X/G48.
