Just try getting mags now. Last I looked, I couldn't find any 15 rd. Glock 22 mags.
Saw some on a site, similar to Gun Broker (sorry, can't remember the name now), where folks sell privately to others (firearms sold via FFL holders). Glock 22 15-round mags were going for $60, plus shipping, EACH. The only mags I saw on eBay were 10-round mags, and even those are going for $30-ish.
But if you stop and think about it, it makes sense to do this, in a perverse way. One of two things is going to happen, likely pretty soon:
1. Extended capacity mags will be outlawed. No biggy, these guys already sold theirs.
2. Extended capacity mags will NOT be outlawed, which will cause the buying spree to slow down, and availability & price will go back down. Meanwhile, they sold theirs for twice as much as they were worth, and now can buy twice as many as they had before! :whiste:
