I had previously sent an email to you stating that this is a very innovative product for the shooter who wants to practice reloads of various types . I use this at home; and, at the range for practice exercises before I go to live fire. This saves the wear and tear on my 2011 magazines, which are fairly expensive, and reduces the need to dedicate mags for reload practice of any nature. No need to retune a magazine that has hit the ground before a match.

Ordered this Mag to carry while running the course in the Heartbreak Run And Gun. It worked perfectly. Kept all the vast mud out of the gun. Plus when not using it as a mag well filler this magazine works great with dry fire practice. Makes the gun feel loaded and the correct loaded weight.

the magazines fit perfectly in my CZ Shadow 2, very useful for dry fire. The weight simulates a full mag

Very well made, sturdy, they feel like the real thing and make dry fire practice more effective. They fit perfectly on my CZ S2

The five pack is a good value, and provides enough dry-fire practice magazines to fill the competition belt, and one in the pistol. They lock in place perfectly, the weight is correct, and the color means no question mistaking the wrong magazine or selecting a magazine with ammunition. For dry fire without the slide locking back, they work perfectly, useful when practicing reset. These magazines work great for practicing mag changes or mag reloads. I purchased a five pack of the CZ mags, and also of the P320 mags; both work flawlessly, and I will be ordering a set for the Glock, as well.

Bought these for Sig X5 and Akai 2011. Fantastic mags that work flawlessly. The weight simulates a full mag. Sent several reloads yard sailing across the garage on concrete floor and they have been very durable. A must have if you want an excellent replacement for real mags for dry fire.
