Excellent, but with one drawback

Pros:

<br>-Cheaper than OEM Glock mags

<br>-100% reliable with grass cased ammo

<br>-Lighter than Glock brand mags

<br>

<br>Cons:

<br>-Very unreliable with steel case ammo, rounds stick and will not feed, also very difficult to load with steel case too. I get probably 5 or 6 stoppages in 20 rounds. It usually requires removing the mag and smacking it against something to get the rounds to unstick.

<br>

<br>I will probably buy more, but with the awareness that steel case is a no go.
