I first used one of these magazines while deployed in Iraq in 2006. I have since used the exact same magazines for two more deployments as well as training. They are heavier than normal magazines but their reliability make up for it.

I have used this product in defense related activities In Iraq and Afghanistan. Quality and reliability are definitely worth the weight.

Just as most everyone has said these are probably the most reliable mags on the market. Definitely the mags I would keep in my SHTF bag. They are a bit heavy but they work 100% of the time, so I will live with the weight

They work and they are worth the money. It just does what it’s supposed to. I can’t express how it gives me peace of mind knowing when I pull the trigger there won’t be feeding issues.

Product appears to be authentic and in new condition. I plan to use these magazines for sport shooting at my Arizona residence. Similar magazines previously purchased work without any issues.
