Mec-Gar MGRP8515B Ruger 9mm 15-Round Magazine

Frequently Asked Questions

Will this magazine work with older Ruger P85 models or only newer ones?

This Mec-Gar magazine is designed to fit all serial number ranges of P85, P89, P93, P94, and P95 pistols. Because Ruger made some dimensional changes to the P-series magazine well over the production run, it's worth checking compatibility with your specific pistol before relying on it for carry. Most users report smooth function, but a test fit with your firearm is good practice with any aftermarket magazine.

How is this magazine different from factory Ruger magazines?

Mec-Gar actually manufactures many of the OEM magazines for major firearms manufacturers, so the quality and engineering are comparable to factory standards. This aftermarket version uses the same core materials: heat-treated carbon steel, music wire springs, and polymer followers. The main difference is manufacturing location and cost. Users report these magazines function identically to factory originals.

Can I use this magazine for both range and defensive use?

Yes. The 15-round capacity gives you the same round count as factory standard magazines for P-series pistols. The heat-treated steel construction and high-tensile spring are designed to handle sustained use, so it works for training, range days, and duty setups. Feed reliability is where Mec-Gar has built its reputation over 50+ years of supplying law enforcement and military customers.

What if the magazine is hard to load initially?

New magazines often have stiff springs out of the box, which is actually a sign of quality construction. A few hours at the range will break in the spring and make loading easier. If you find loading challenging, a magazine loader tool takes the strain off your hands and extends the spring's lifespan by reducing repetitive stress.
