Only reasons to NOT go OEM Glock magazines:
Price
Availability
Reasons to go with aftermarket mags other than price & availability
You want to try something different so you can be an expert when recommending stuff on forums like these
You want the see through bodies (ETS)
They are easier to disassemble (OEM are a bear to take apart!)
I don't have as much experience as many of the other CGN members on this website. I have only ONE KCI 10/33 magazine which I bought because I didn't know any better back in the day. It runs as well as any of my OEM Glock magazines. But I have heard horror stories by others both in Canada and in the US
I have used both factory ten rounders and pinned 10/17 on both my G22 (40cal with an extra conversion barrel) and my G34 Gen5. The only time I EVER have a hiccup is when I load 9mm into the 40cal mags. They work in a pinch but not recommended and especially not in a self defense situation!
