I scored some factory new Sig P-225 mags for under $40 a piece.
Oh, and a note to folks buying a single used mag for $40 or more on gunbroker (or god forbid Promags) You are all idiots. TGS has new ones (shockingly they're even in stock!) for not much more than that. I just refuse to pay that much for mags.
I really wish I'd bought 10 mags back when I could get them for ~$25 each.
