This little magazine is extremely durable and pays for itself in hours. I've increased my accuracy beyond my wildest dreams in days. I was able to qualify for my EHCCL one handed because of this magazine.

Slightly heavier pull than stock glock, but not too bad. Allows for you to do follow up pulls and target transitions. Must have for high quality dryfire training.

This is good for practicing trigger pull and reset without having to re-rack the pistol. It does not work with firing pin triggered lasers. Its also pretty expensive for a plastic magazine with a lever, spring and clicker. It also doesn't feel EXACTLY like a trigger pull. Its close but its not the same. It is a relatively tight fit so you will need to push it harder into the grip than a normal magazine. The first trigger pull after inserting is also pretty hard because you are pulling both the magazine trigger lever and the firing pin. But after that it is easier to pull the trigger. UPDATE: If you use this with a Mantis Dry Fire Training Aid, the Mantis will pick up the release of the trigger as a trigger pull. So a 10 trigger pull drill will show up as 20 trigger pulls. The release of the trigger is the same sound as the pull of the trigger. I deducted a star since it can't be used with the Mantis system nor with a laser dryfire cartridge trainer. These magazines are only good for trigger pull and reset training and for that they are not exactly like the trigger pull so I am questioning value now. I will be returning these.

Love my new Dry Fire Mag. Allows me to practice the trigger without having to wrack the slide with my Glock G47 MOS. Highly recommend. Will save me some ammo.

When I bought the mag, i thought that it did not fit. You have to push it forcefully to fit. It is a very tight fit into the weaponon first use. I thought that it was too small, but it actually fits.And works excellent for dry fire training.Love it.
