Description
The Mec-Gar MGRP8517N brings something genuinely useful to your Ruger P-series collection: two extra rounds of 9mm capacity while maintaining the same profile as factory magazines. Most P85 shooters know the original 15-round mags, but if you want more ammunition on board without the magazine protruding from the grip, this is your answer.
Mec-Gar has been making magazines since 1965, and that experience shows in every detail. The nickel-plated carbon steel tube is heat-treated for durability, so it stands up to years of range time without deformation. The high-impact polymer follower keeps rounds feeding smoothly, and the music wire spring maintains consistent pressure whether you're running 115-grain practice loads or 124-grain defensive rounds. The metal floorplate sits flush with your grip, so drawing and holstering stays clean and snag-free.
Flush-Fit Design with Extra Capacity
When Mec-Gar designed this mag, they used a patented design that squeezes in two additional rounds without making the magazine longer. That means you get 17 rounds but your P85 still looks and handles like it was built for 15. Factory magazines hold 15, so this gives you tangible more firepower without the bulk.
Built to Military and Law Enforcement Standards
Mec-Gar doesn't make magazines as a side business. Brands like Sig Sauer, Browning, Remington, and Walther rely on Mec-Gar to build their OEM magazines. That's not marketing talk, that's production reality. The magazines they make under their own name use the same tooling, the same materials, and the same quality control. This magazine will outlast most of the pistols it gets installed in.

Frequently Asked Questions
Will this 17-round magazine work with my Ruger P85?
Yes, this magazine is designed for the P85 and all compatible P-series models including the P89, P93, P94, and P95. The 17-round capacity with flush-fit design means it functions like a factory magazine but holds two extra rounds. Some early P85 models may require a firmer insertion initially, but that's normal.
How is this different from the factory Ruger magazine?
Factory P85 magazines hold 15 rounds. This Mec-Gar magazine holds 17 rounds while using the same flush-fit profile, so it doesn't add bulk to your grip. The nickel plating provides corrosion resistance, and the heat-treated carbon steel construction is more durable than some factory options.
Can I use these magazines with other Ruger pistols?
This magazine is designed for Ruger P-series pistols in 9mm, specifically the P85, P89, P93, P94, and P95. It does not fit newer Ruger pistol designs or different calibers. The original PC9 carbine (discontinued 2006) will accept it, but the newer Ruger PC Carbine does not.
What makes Mec-Gar magazines reliable?
Mec-Gar has been manufacturing magazines since 1965 and produces OEM magazines for Sig Sauer, Browning, Remington, and Walther. This magazine uses Italian manufacturing with heat-treated steel, high-tensile springs, and precision tolerances developed through decades of military and law enforcement service.
