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
