I would buy them again

Feels like good quality. Got them for an h&k compact witch normally have 8 round mags so these are great for extra rounds. I put 15 rounds through each (bought two) and had no issues at all. Wish I got two more when I had the chance.
excellent quality

Good mag
Review by Theo
Verified Buyer
Good mag for the range, because they get stuck a little on release.. but run them a few times and they start to drop out smoothly.
Good for training?
Review by D Otis

I bought 4 mags. 2 of them do not fully eject from the receiver. They hang up about 2/3rds of the way out. Kinda reminded me of the old non-lined glock mags. Not a huge deal at the range and I can work that into my training. The other 2 don't move at all when the mag paddle is depressed. I've tried everything to get them to move and they just sit there. They do come out when I manually extract them. This occurs when empty or fully loaded. Over all for the price and my intended use as range mags I'm feeling okay about the purchase.
Great Value

Bought two of these for my HK45. Fit and function is perfect. They drop free and lock the slide back on last round. Will be ordering more, am very pleased with the mags and shipping was quick

I have a 2014 HK45. I initially ordered four magazines. Upon comparison with factory mags there was little difference other than logo badging. All four magazines function perfectly. From locking the slide on the last round to dropping free upon ejection. I have ordered eight more. I have a similar number of factory HK magazines. I just prefer to use these on the range. Twelve factory HK magazines cost me $430.00. Twelve United Defense LLC magazines cost me around $160.00. I could have saved more by placing one order.

This is the most inexpensive magazine that you can currently find for an HK45. Current stock HK mags at best are $35.00 prior to shipping charges. United Defense LLC mags currently run $14.95. If you look on the internet for a coupon code you can lower the price of individual magazines to as low as $12.00. Keep Shooting shipped my orders out the next business day with email notification of tracking info. They use Fedex Smartpost.

I highly recommend United Defense LLC magazines for use in HK45's. You can find detailed measurements and comparisons to factory magazines on the HKPro web forum. Keep Shooting quickly processes and ships orders. Overall a great experience.

Thank you

Good range mag

These are well made, and I can't complain too much for the price compared to a genuine HK mag. That being said, don't expect these to be a perfect clone. I bought 3, and all are NOT drop free like a factory mag. All of mine hang up in the magwell and won't make a clean ejection, but you can still clear them out without much effort. I mic'd all of mine and they are .005-.007 wider than a factory mag, which is enough to cause them to hang up.

So its a good range mag for the price, however if you need one for duty, stick to the factory mags.

Got two. I have a HK45CT -- and while these are too long for the 45C and CT, they still fit and function as 10rd mags. You can buy the elephant foot at HK parts and make them fit like a stock mag. Great product for an amazing price!

Bought two of these for my new HK45. They were on sale for a great price and shipping was cheap and fast. Matching with originals only difference is they don't have "Made in Germany" on them. Other than that function without an issues at all. Ran 100 plus rounds thru them with no issues at all. Liked them so much and price was great bought 2 more.
If you need some spare mags for your HK45 do not hesitate to pick some of these up.
Excellent magazine for the price!
Review by Robert A.

I purchased two of these magazines as a comparison to my OEM HK45 magazines and upon receiving them I took my OEM and the aftermarket brand magazine apart and they are identical almost down to the weight. The only difference between them is that the HK logo is not on these magazines, of course. I did a short test on them and put about 20 rounds through each and it fed through my HK45 flawlessly and locked the slide back on the last round every time. I do not foresee these magazines having any issues in the future, but only time will tell.

I would highly recommend these magazines to anyone looking for a cheaper replacement to OEM HK magazines.
