1.  Periodic disassembly and cleaning with soap, water and a toothbrush is suggested. Do not use solvents or other chemicals. Dry well and lightly spray spring and interior of mag with WD40 prior to assembly.

2.  We have tested and experimented with over 8 major offerings of ammo and as expected, there is a HUGE difference in the feeding, performance and reliability of the different ammo brands. You will have a very difficult time adjusting the mag using some brands of “bulk” ammo since some of the bullet profiles are difficult to feed and many of the rounds are not full power which will result in poor or failed ejection.

We recommend that you test with CCI solid round nose MiniMags to minimize the effect of ammo on your adjustments, then after the mag is adjusted, bulk ammo should also work well within the limitations of the ammo.

3. Occasionally new mags will require a minimal break-in period as evidenced by the inability of the mag to keep up with the feeding speed required. If your ammo is sticking in the mag, you should:

A. make sure the mag is clean on the inside. Dirt and carbon and unburned powder will increase the drag on the bullets and will slow down the feeding speed and ability.

B. Especially on new mags, occasionally some of the glass fibers in the mag that give it strength will be close to the surface and will increase the drag resistance on the follower. Disconnect the follower from the spring and manually slide the follower up and down the inside of the magazine on the rails simulating use and the follower will polish to the mag. Spray a light mist of WD40 on the inside of both mag pieces prior to assembly. The more the mag is used the smoother it will get.
