33 round mags are getting hard to find. I bought 2 Glocks and one KCI and two KCI 15 round mags. I got the KCI mags 1-33 2-15 plus a mag pouch for 40 shipped from CTD. These are well made and work well. They drop free and are a great buy. I paid 40@ for the glock mags. I did not need them but even though I don't see a Federal ban on them I could see Glock bend to the police Dept's. saying they are going to sell of their Glocks and buy other guns if Glock does not voluntarily pull them. I saw Winchester do this to Black Talon in the 90s. Now the stuff goes for 50 a box.
