Don't know if this is common or if it's just me. The two pics below are of two of my p3at mags. The first one has two triangular pieces missing out of the back of the mag. One piece missing on each side. Then it is cracked down a little bit off of the bottom of the missing pieces. The second one has two cracks where the first mag has the pieces missing. You can tell where the crack is on the right side but the light glare. Sorry the pics kinda suck but my camera doesn't take the best up close pics, or I don't know how anyway... Don't use either of them because they will no longer hold the mag follower in. Are the mags covered under the lifetime warranty? Just wondering even though I already bought a couple more. Any reasons as to the cause of this?
