Ive got 3 or 4 Ive thought about selling. I know they probably aren't work much here, but maybe if I put them on a national website, or calguns, etc, they are probably worth something.
As for IDPA (or even USPSA for that matter), you have a limit of 10 rounds in production class, but you can use any mag. You just can't load it with more than 10 rounds.
I paid $10 for used 10 round mags and thought I was getting a deal a few months back. New ones are 3 x that much and you don't usually see used Glock magazines for sale very often.
Awhile back-few weeks ago-I bought, from an INGO member 6/15 rounders+2/10 rounders. The Hi-Caps were $10.00 each, the 10 rounders were $5.00 each..If that gives you an idea?? They were .40 cal. for a G-22...Bill..
Got a 10rd 9mm which I'm pretty sure is a G19 that came with my Sub2000 that I'd let you have just to add to the pot, if you were closer, but I'm not going anywhere just to dispose the thing. If you're ever going to be in Carmel, let me know.
