M3 Grease Gun Magazine
This is a 30-round .45 ACP box magazine for the M3 and M3A1 submachine guns, the stamped steel guns nicknamed the Grease Gun. United Defense makes it new to the original military design. Original magazines are getting older and harder to find in good shape, so this gives owners a working spare. Collectors and reenactors can also use it to complete a correct-pattern setup.
Features
- 30-Round Capacity — The magazine holds 30 rounds, the same load as the original issue magazine.
- .45 ACP Calibre — It is chambered for .45 ACP, the pistol cartridge the M3 and M3A1 were built around.
- Fits M3 And M3A1 — It is designed for both the original M3 and the simplified M3A1 version of the submachine gun.
- USGI-Pattern Design — USGI means US government issue, and the magazine follows the dimensions and layout of the original military magazine.
- Stamped Steel Body — The body is pressed from sheet steel, matching how the originals were made, and has a reinforcing plate riveted near the top.
- Blued Finish — Bluing is a chemical treatment that darkens the steel to a deep black and gives it some resistance to rust.
- Steel Follower And Spring — The follower, the plate that pushes cartridges up to the feed lips, is steel, and so is the spring under it.
- 230-Grain Ball Ammunition — It takes standard 230-grain ball, the full metal jacket round that was the military load for .45 ACP.
- Detachable Box Magazine — The straight box design inserts and drops free like the original magazine and carries the cartridges in a single straight column of the body.
Build And Fit
The magazine is all steel: a stamped body, a capped floorplate at the base, and a steel follower and spring inside. It is built to the original specification rather than redesigned, so it seats in an M3 or M3A1 magazine well like the issue part. The blued black finish matches the look of original magazines on a period gun.

Excellent condition, worked wellI purchased these for a VMac 45 I built. I was expecting to have to modify them, but I guess the VMACs are already set up for OEM grease gun mags, as they worked fine out of the gate. No issues. The overall condition was excellent, with no scrapes or chips.

Mag does the jobMy old mag finally gave out after years of abuse and I wasn't about to keep fighting with a bent feed lip every range trip. Package showed up two days early which was a nice surprise cause I had a range day already planned for that weekend. The United Defense build quality is definitely a step above the cheap knockoff I had before. Only gripe is the fit was a tiny bit snug going in the first couple times but it loosened up after a few insertions.
Quality feels durable compared to other budget options
Fit was snug at first, needed a few cycles to break in

Feds greatGot this for my MAC10/45 build and it dropped in clean, no cutting or fitting needed. Loaded up all 30 rounds of 230gr ball and ran a couple mags through with zero issues at the range last weekend. Spring tension is STIFF though, my thumb was sore after loading two of em, wish they threw in one of those old GI loading tools. Witness slot on the side is handy for checking if its seated. Overall real happy for the price.

Fits my grease gun perfectOrdered two of these and they showed up in like 3 days, way faster then I expected. They lock into my M3 nice and snug and the finish looks right next to my original GI mag. Ran about 90 rounds thru one so far with zero hiccups. Very happy with these.

Perfect fit for my grease gunBeen looking for a good replacement mag for my M3 for a while and this one dropped right in no problem. Loaded it up with 30 rounds of .45 and ran a couple mags through at the range last weekend, fed every single one without a hiccup. The spring feels strong and the body is solid metal not some cheap junk. Only thing is the last few rounds are a bit of a pain to load with your thumb, kinda tough on the fingers.
Fed every round no jams
Wish it came with a loader tool
