    Magazine Review

    Posted by Brian J. on May 13th 2024

    Very happy to have received these magazines. I am switching from my Dan Wesson DWX to the Grand Power X-Calibur (old model). The quality and materials are as good as anything else out there. I took these to the range right away. They all worked great right out of the box/baggie. No failures whatsoever. The only issue was, I was not able to fill them to capacity. I was only able to get 18 or 19 into each. Getting those 19 into two of them was a real effort. I'm hoping this will resolve itself as they break-in. That is the only reason I gave 4 stars.

    Magazines are high quality, function is flawless, pair that with excellent customer service from Global Ordinance and I couldn't be happier. Thanks again G O for setting you standards so high!

    Good Magazine but....

    Posted by J F on Jul 3rd 2021

    A good quality magazine. As others have mentioned, you wont be able to get 20 rounds in initially. It took several weeks of regular use but I was able to go from 17 rounds fitting at first to finally 20. Expect a lengthy break in period but it will fit 20

    Grand Power 20 round magazine

    Posted by Mitchell Cox on Jan 17th 2021

    Mine wont hold 20 yet , i got 18 in it today, first time trying it out at the range but zero malfunctions for over 200 rounds shot. Maybe after the spring breaks in some i will be able to load 20 rounds but the extra round count and the quality of the magazine was worth every penny.

    Grand power 9 mm 20 round.magazine

    Posted by Rob Lenker on Dec 31st 2020

    Well overall I'm happy with it. It sat for seven days before shipping only approximately sixty five miles to me. I was hoping since it was close I'd get it pretty quick lol. It seems to be well made only one drawback is that it doesn't hold 20 rounds. You can cram 18 in it but again I'm happy with it being three more than what I had. I'm just not really excited about almost 11 days shipping for just a short distance because of sitting in the warehouse before shipping.I'd of liked to have had it with me on my trip but it was waiting for me when I came back home. ☺

    Awesome Magazines

    Posted by Sean McDonald on Dec 18th 2020

    5 star all day these sweet babies are steel & nitrided treated magazines with the high visible orange followers and Grand Power logo. A must for competition shooting or just plinking.
