The girlfriend has returned from her Glock armorers course with abuncha swag, a very nice book, some misc. accessories and a certificate of,well, certification, I guess.

She did learn one thing that surprised even me – how to tell the difference between pre-ban (pre-1994) and post ban (after 2004) magazines. This is important because many places still have this evil ban in effect and it would be very tempting to take recently made mags, which lack the ‘law enforcement only’ markings and claim they are from before the ban. Well, here’s the deal, as related to me by the girlfriend –

Pre-ban mags had the caliber marking stamped on the back of the mag between the top of the witness holes and the ‘U’ shaped cut out at the top of the mag
During-ban mags had the caliber markings moved up higher to accomodate the ‘LEO/mil’ warning that was stamped on themag
Post-ban mags keep the caliber marking in the same location but it is no longer centered between the witness holes and the top of the mag. Basically, its in the same location as it was during the ban but the warning text was removed, leaving a larger space under the caliber.

If your mag has no caliber markings it is an ancient magazine that was from when Glocks only came in one flavor, and is definitely pre-ban (and isnt drop-freee either).

So before you buy a stack of recently mafe Glock mags figuring the cops won’t know the difference…..(Well, most probably won’t and have better things to do than go after people for these types of things. But some dont and will be happy to cause you grief.)

Lotsa interesting stuff was taught, it seems.
