  1. Sal Desimone CT

    I went to school for engineering and worked in a few precision machine shops including a gear cutting house. I recognize precision and quality. I have never seen a magazine with such quality and attention to detail. Firstly the design and function is perfect if you follow Gary’s instructions with regard to COL 1.610 to 1.645. I am using 1.620/1.625 COL and the mag functions flawlessly. The dimensional machining tolerances are tighter than anything acceptable for most other quality magazines. I had contemplated selling my Deerfield 9944 over the years because of the low mag capacity but not now. The rifle has double duty, home defense and hunting. Apply a little silicone on the sides of the magazine and the wood stock that they mate with and the two will break in very quickly. Awesome product in both design and execution! A real show of AMERICAN ENGINUITY

    I received my order today, thanks. I have the synthetic stock and it rubs pretty hard on the magazine sides, after I use it a while I will file the stock opening a bit to make it not so tight.

      David we have found that a little lube on the head of the magazine makes insertion and removal much easier. Due to the weight of a loaded magazine a “snug” fit assures the magazine stays in the gun.

    Just returned home from the range . Your mag performed flawlessly. With both ,slow deliberate fire and mag dump. These magazines are incredible. Thank you much for bringing them to reality. I’ll be ordering another.

      Brian, Thanks for the feedback. What ammo were you shooting with our magazine?

  4. David Hineline (verified owner)

    So I filed the rough edge really just a synthetic burr right at the bottom of the stock and the mags insert and remove find now. I will try a dab of lube, I am loading Berry’s 240gr HP plated double struck bullets, measuring them they are just a few thousandth shorter than your recommended minimum length. They fed perfectly, there is a lot of tension upwards on the ammo in the magazine, so the operation of opening the bolt has more drag than with the 4rnd factory magazines, which I can not imagine I will ever use again. The extended mag release makes the factory 4rnd mags truly drop free, and with practice the 10 rnd mags will be quick also.

    David H – I experienced the opposite. My wood stock will need a scootch relieving in the mag well area, whereas in my Ruger synthetic is glides in perfectly. Regardless, these magazines are incredible, built like an A-10 Warthog and certain to survive a nuclear (or as GWB would say, nucular) blast. Thank you, IQ Munitions !!

      Thank you Ray, maybe we should call the magazine the A-10 Warthog!

  6. randy (verified owner)

    the mags are great but having them IN COMBINATION with the extended release allowing one handed mag change while holding firearm with trigger hand is even better—currently feeding RCBS 300 grainers in middle of length range and nary a problem. will be checking sierra, nosler & hornady jacketed 300s while HPing the RCBS mold with erik @ hollowpointmold.com

  7. Brian Albarado (verified owner)

    This magazine makes the 77/44 worth owning. It’s easy to load and feeds just as smooth as a factory mag.

  8. Frank B (verified owner)

    Magazine arrived quickly and on time. Tested the magazine in my ruger 99/44 with 20 rounds of 225gr FTX Hornady Leverevolution ammo which I.Q. Munitions lists as a suitable factory round. I loaded the magazine twice, each time with a full capacity of 10 rounds. I had one hang up half way through the first 10 rounds and no issues with the second 10 rounds. My magazine fits a little loose in my gun but overall I am extremely happy with this product. Well worth the price in my opinion. The magazine is made so well that I believe there is a little bit of a break in period with it. I plan on buying at least one more when they come back into stock. Thank you for bringing this product to market and with such high quality. I would not be surprised if ruger starts producing the 99/44 again as a result of your magazine. I would really enjoy seeing this magazine offered with a polymer body as well as the aluminum body. This would create a lighter more budget friendly version of your incredible design. Oh yea, and it’s made in Montana!

  9. Jimmy (verified owner)

    These are high quality! I filled it up twice with various SJHP, Hornaday XTP’s, and some LeverEvolutions and they all loaded and ejected perfectly in my 77/44. Thanks for producing such a quality magazine. I also have the extended mag release and that was another great improvement to this rifle. I’m ready for the 357! Thanks again!

    Did machining for for thirty years, MILLS, CNC ,HOBS, LATHES, and more, VERY NICE QUALITY. I’ve cycled it through the rifle but have not actually shot it, but I feel confident it’ll be great. By the way both my sons purchased one seeing as we all hunt with the same Ruger. Thanks Jim

    • iqmunitions_w6l0in

      Wow, the whole machining crew over here doesn’t yet have as much combined experience as you-alone, sir. Thank you for your kind words.

  11. Paul swanson

    I received my clip and extension release kit and was very pleased. The installation video was an excellent resource for making the install easy. The clip is very well built and slides in and out with ease. No cycling issues. Any more clips coming available? Do you have any plans for designing and building a synthetic folding or bullpup stock for the Deerfield?

    • iqmunitions_w6l0in

      Some…day…still… we will be making magazines again.

  12. Sam Noller (verified owner)

    Built like a tank! Pretty sure an 18-wheeler could run over it and not damage it. It fits my Ruger 96/44 lever action perfectly. My 99/44 semi automatic needs just a bit of wood removed from the mag well area.

  13. Kenneth Iddins (verified owner)

    Are you folks still making/offering the 10-round .44 magazines? Superb craftsmanship and machining. Wanting to purchase a second one. Also an extended magazine release, for a Ruger Deerfield. thank you for your time, Ken

    • iqmunitions_w6l0in

      We are still in the throes of getting a US based injection molding company to make the main bodies, which is proving to be a chore, unfortunately. There will be more magazines..!!… someday…

    I received my Magazine in the UK today and had no problems with Customs from the US or UK due to using Easy Export. I have not had chance to test it yet, but the magazine is very well made, strong and lightweight. It fits my 96/44 perfectly. The whole sales and shipping process was made so much easier by the excellent help of Davis, who even phoned me while I was in Italy to ensure payment was taken correctly. Thanks for a great product, I should have brought more!

    Looks and feels SOLID!!! Have not tried my mag yet because it came one day before vacation. But when I got home I tried putting 10 rounds in it and for the life of me I cant get the 10th round in the mag. Anyone have any advise??? Thank you!
