Source for used/ Police turn in Glock 17 mags?

[UnSafe]

For my next long term project, I'm building a Frankengun from a $279 G22 (Summit Gun Broker's "Friday Specials"), using a LW 9mm barrel, tall sights, suppressor and cut in optic mount. Right now, I'm just looking for 9mm 17rd mags and don't mind buying used.

Anyone know of current used factory Glock G17 mag deals?

I've used the Magpul Glock 17 mags with no problem and they can be had for around $15.

ETS mags work well too.

Summit Gun Brokers has used magazines; used $15; new $25

aimsurplus.com usually has them pretty cheap.
