I.Q. Munitions’ Extended Capacity Ruger 77 Magazines


    Stacked up and ready to go - Ruger 44 Magnum magazines. All proudly made in the USA.

    Who are I.Q. Munitions?

    I.Q. Munitions is a Montana-based firearm industry company originally focused on perfecting high-velocity cartridge loadings whilst maintaining accuracy. This evolved into working with subsonic rounds, and how to create more accurate and effective subsonic loads. This is evident with their ‘Magnuforce Subsonic’ line, which covers a 400-gr 44 Remington Magnum, a 550-gr 45-70 Government and a 575-gr 500 S&W.

    Extended Magazines for Ruger 77 Series and Ruger Deerfield

    Gary, the owner of I.Q. Munitions, has a personal love for the venerable 44 Remington Magnum round, and this passion gave rise to creating a 10 round detachable magazine compatible with the now out-of-production Ruger Deerfield semi-automatic carbine, and the in-production Ruger 77/44 bolt-action rifle. The magazines fit, and will chamber in Ruger 96/44 lever action rifles, but have issues with extracting. I.Q. Munitions are seeking to fix this issue.

    I.Q Munitions’ 77 Series Extended magazine release

    But wait, there’s more!

    I.Q. Munitions, rightfully seeing the popularity of their 44 Magnum magazines, have announced they are prototyping 357 Magnum versions suitable for the Ruger 77/357, with a soft due date around the end of 2020/start of 2021.

    Ruger 77/357’s just got an upgrade!

    I think that the extended magazine definitely gives a much-needed upgrade to the 99/44 and 77/44 (and shortly the 77/357), allowing you to spend more time shooting, and less time reloading. What do you think? Let us know in the comment section!
