I need another 15 Rd Glock20 magazine. Any advice other than than buying from Glock? thanks in advance. I would prefer a 15 round because it will fit in my mag pouch on chest rig.

This is a good place to start. I've had good luck with them.
I watch reddit.com/r/gundeals and wait till I see someone with a good sale. Then I stock up. I think I have about 10-12 counting the ones I have converted to 30 rounders.
I've been buying them from Midway when they have a sale. The last ones I bought were $17.95 each.
Midway has them for 19.99 a piece atm: https://www.midwayusa.com/product/714785/glock-magazine-glock-20-20sf-10mm-auto-15-round-polymer-black
Midway has them for $16.74 today (one day sale all Glock mags). If I didn't already have 10, I'd be buying more at that price!
Ordered 3 G20 magazines from MidwayUSA this morning at the one day price. They had the box in the mail in less than 1 hour from their order confirmation e-mail. That is what I call fast.
