I have the following for sale:
4 Glock 19 mags, 15-rd capacity. (SOLD, pending funds)
3rd generation mags, with 9mm-3 followers. Used, good condition. I have not been able to get these mags to work reliably with JHP ammo; but my gun works perfectly with new production mags and 9mm-5 followers. Go figure. I cannot guarantee these mags will be reliable with your gun/ammo. Because of that, I'm selling them dirt cheap. NO returns on these; sold as-is. All 4 for $20 shipped USPS to the lower 48 states.
2 Glock 19 POST-Ban 10-rd mags. Barely used; excellent condition. Worked flawlessly with FMJ ammo; never did try them with JHP ammo. $15 for BOTH shipped via USPS to the lower 48 states. (Sold pending funds).
I accept personal checks (held a week to clear), or POSTAL money orders.
