OEM Glock Mags vs aftermarket

ordering a Glock 23/19 conversion barrel and trying to find a couple of OEM glock 19 mags...only ones I can find from well-known online retailers are 10-round mags. I've seen some Magpuls and Pmags, but can't find an OEM 15rd Glock 19 mag. Any ideas?

CDNN Sports has 15rd $19.95

Looking at that now, it says 5th gen. Will the 5th Gen mags work in a 3rd Gen?

Nevermind, looks like G5 mags will work in G3 guns (and vice versa if you haven't flipped the mag release for a lefty)

magpuls are legit

Found a couple places locally that have the OEM 19 mags.....Woods N Water wants $40 each. Plus One Tactical in Tuscaloosa wants $27. I like $27 locally a lot better than $20+shipping online. Think that's gonna be a winner

I wish someone would make magazines for the Sig P365. $45 ea for oem magazine and no alternative.

botach has them for $18.95 + free shipping HERE

i have some magpaul i got for around $10 each, havent had any problems with them and they make good range mags, they're all polymer and dont have the round counter in them. the kci (korean) are almost identical to the oems and can be had for pretty cheap. But for home/self defense oem is the way to go.

ETS mags work well too. For range mags you can't really go wrong with any of these choices.

For home/self defense I am with GH - oem is the way to go.

Botach and jimbobs have the ets mags cheap
I just order 3 17rd and 3 30 rd, but haven’t shot them. They get good reviews

I’ve ran magpul in competitions several times now and haven’t had a single problem out of them
