Each Keepshooting.com magazine, including our brand new M3 Grease Gun magazine, begins with a guarantee. Our goal prior to production is the manufacture of a magazine that is not only 100 percent functional, but also 100 percent reliable – a goal that took several years to reach with this particular magazine. As such, we guarantee the function and reliability of all of our house-brand magazines 100 percent. If for any reason you are unsatisfied with the performance of your magazine, it can be returned for a refund of the purchase price provided it is free from modification, damage and visible signs of usage or wear.

How can we offer such a guarantee? Prior to release, a random sampling of every magazine we produce is rigorously field tested to ensure proper fitting, feeding and ejection. Not to mention, our magazines are manufactured using premium raw materials alongside modern manufacturing technologies. If this sounds expensive, that is because it is. But due to the number of magazines we have made, our prices are driven down and in turn passed on to you.

As noted, the M3 Grease Gun magazine is a detachable box magazine that boasts a familiar design based on the original military M3 submachine gun magazine, but with several much-needed improvement. As such, these magazines are guaranteed to fit and function reliably in any M3 submachine gun, including the M3A1 variant. This magazine is also compatible with the MAC-10 and its many variants and derivatives. The body of the magazine, which is designed to hold and feed 30 rounds of .45 ACP ammunition to your firearm, is constructed from hardened steel that has been fully heat treated. It also boasts a blued finish for enhanced protection against rust and corrosion. Additionally, both the steel spring and follower are precision manufactured to provide for reliable feeds on a consistent basis.

Features:
  • Patterned After USGI M3 Magazine
  • Holds 30-Rounds of .45ACP
  • Works With Any Gun Designed to Use USGI M3 Magazines

I just bought 2 more for my AR-45 because how impressed I am about the quality (they are metal and made very well) and the price.
If your weapon accepts these mags, don't hesitate to buy at lease a few. You won't be disappointed.

No mod mag for MPA10T pistol

Ordered the grease gun mags on a thursday, received them the following Monday and only selected the cheapest shipping at $10 for the 3 mags. Outstanding order processing and shipping. Usually I have to wait for other companies to process your order for at least a week or 2 and these guys get my order processed and shipped to me in 5 days which included the weekend. Just awsome. As for the magazines themselves the over all continue looks great (after cleaning the grease off) they all fit my Master Piece Arms MPA10T just as good as my factory mag and even though I did NO altering to the mags I couldn't pull them out of the mag well even forcefully. I only put 10 rounds thru each mag (ammo costs prevented me from doing a full 30 Rd per mag function test) with only 1 false to feed which was my fault for not fully seating the mag. My gun ran like a champ with them so now I'll be on to loading a mag up fully and letting it sit for a month or so and see how it feeds then. Other than that for the $15.95 these mags are you can't go wrong if you are gonna run them in a MPA10 varient in my opinion. Can't wait to see if they get any sten mags back in to try out in my MPA30sst. Figures crossed :) Review by Brett (Posted on 8/17/2015)

These work flawlessly in the MAC 10 during both semi auto and select fire. I've never had a problem with them during loading or 'unloading' at any rate of fire. I would not hesitate to buy more of these. I prefer them to the originals and I recommend them to friends with MAC 10s. Review by OCR (Posted on 4/16/2015)

I was looking for a cheaper mag for my MPA Mac 10 45 and I happened to run across these on sale for $15.95. I was really impressed with the quality of these mags. They are well built and have a nice blued finish. They look and seem better built than the orginal mag that came with my gun. The Masterpiece Arms web site wanted $35,95 plus shipping for their mags. These are cheaper and better quality. Review by Michael (Posted on 4/11/2015)

I bought ten of these magazines and each one functioned flawlessly with the Lage thumb release grip for my M10/45. Great fit and finish on the magazines, so much nicer than the surplus originals. Review by Desperado (Posted on 6/16/2014)

I originally bought these to use in my Uzi with a aftermarket grip handle that allows the use of GGMAGS AND THEY WORK PERFECTLY IN THAT GUN
I recently built a AR45 in 45ACP and with the use of a custom lower that has a mag well that's made for GG mags these mags are feeding it perfectly as well
Overall really nice mags that fit and feed flawlessly
I will definitely be buying more of these in the near future
Thanks KS

I bought 10 of these for an AR15 pistol in 45 ACP. For this application they had to have a notch milled in the left side and the back of the magazine and the forward part of the feed lips had to be filed down for bolt clearance. They were full of grease and had to be thoroughly cleaned but they performed flawlessly once they were adapted to the Bazoka Brothers lower. Review by Robert (Posted on 3/4/2014)

I purchased a Masterpiece arms carbine and bought 6 of these mags for it. I had heard horror stories about grease gun mags and was expecting the worst but once on the range the word Flawless came to mind.. I ran through over 200 rounds without one malfunction and will be buying more of these quality magazines Review by Curt (Posted on 1/25/2014)

Superior to OEM Magazine

I just received my order of two magazines yesterday... and I am highly impressed with KeepShooting. This product is superior in every way relative to the original MPA 30rnd mag provided with the firearm. The fit and finish is clean, the rounds feed without any issues, and the construction is solid.

I placed my order on a Saturday (holiday weekend, 31AUG), and the KeepShooting order tracking system kept me informed of the progress of the order as it was processed on the next business day, shipped, and tracked (via USPS).

So, a better product, excellent service, simple and easy order process, what more can you ask for? The price from KeepShooting – is about 40% of the OEM… Need I say more?

Not perfect right out of the box

I bought 10. Some were a little tight fitting. Several would not load or feed properly. The follower kept getting stuck. I finally after loading and unloading a few dozen times was able to get the follower to move freely and the magazine started feeding properly. I'm dropping the quality to 4 stars since production seems inconsistent. I've only been through half the box at this point and I still have one mag that refuses to feed smoothly. Oh get the speed loader. Loading by hand royally sucks! Review by sloppydogdrool (Posted on 6/18/2013)

These fit and function in my 45 Uzi better than half the Mil-Surp mags I have, Plus they match the Uzi finish!
When I bought my 45 Uzi SMG, the only mags you could get for it was the 16 round Uzi Mags. Using 16rnd mags in a sub gun gets frustrating changing mags! And then the price of those 16rnd mags on top of it.
When Vector Arms came out with the replacement grip that converts your 45 Uzi to use grease gun mags I thought I finally had it made, Of course Mil-surp GG mags weren't so cheap or easy to find then either. When I found these I only picked up a couple to try them out, Once I took them to the range I was sold! These fit right in the mag well and feed the gun as fast as it can spit em out! Having them match the color of the gun don't hurt either.
I'm planning on building a 45acp Upper for one of my spare AR lowers this summer and when I do these will be the mag I use to feed it.
No worn out springs, dented mag bodies or bent feed lips on these, they are 100% brand new and work like it accordingly The best part is they cost about the same price as the questionable "Un-Issued" Mil-surp mags you run into using the originals and finding a new spring for a GG mag is not a casual chore!
If you have anything that uses GG mags these are the way to go.
