About two months ago I bought two 32-round ProMag 10/22 magazines because they were cheap ($20 each). I noticed when I first got them the geometry of the feed was a lot different from a Ruger magazine but they seemed to work okay - for about 200 rounds each. Went to the range today and kept getting misfeeds from one of them and it looked like this - note the stock Ruger BX-25 next to it. Cheap pot metal next to the real stuff.
The other ProMag magazine is severely worn too, it just doesn’t have a piece broken off of it… yet. Guess what magazines I won’t buy any more of. Guess what magazines got thrown in the trash today.
I bought some ETS Glock mags for my S2K. So far after about 300 rounds each they’ve worked fine and don’t show any abnormal wear.
Any other 10/22 magazines besides Ruger that are any good? I liked the higher capacity of the ProMags.
