  1. HK45 Magazine Options review by John on 4/2/2018

    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

  2. Good range mag review by CR on 6/2/2017

    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.

  3. Awesome review by Michael on 5/8/2017

    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!

  4. Great review by Scott on 1/29/2017

    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.

  5. Excellent magazine for the price! review by Robert A. on 2/14/2016

    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.
