DENVER — Colorado gun stores are running closeout sales this weekend on magazines that hold more than 15 rounds.  A new law banning these magazines takes effect Monday.

The Mags For Freedom event at Glendale’s Infinity Park — what organizers are calling a “Farewell to Arms Freedom Festival” — drew about 4,000 or 5,000 people on Saturday, according to early estimates.

“Glendale is surrounded by the City and County of Denver and we’ve been this little island nation that has ensured individual rights,” Deputy City Manager Chuck Line said.

Magpul gave away 30-round magazines to the first 1,500 people through the gates. Participants were also able buy up to three magazines for $10 each.

“Tonight’s turnout, which exceeded all of our expectations, reflects the passion that Coloradans feel about the way in which this Democratic legislature has eroded the Second Amendment rights of its citizens,” said Free Colorado spokesperson Kelly Maher, who MC’d the event.

Political commentator Dana Loesch keynoted the event, and arrived at the event on the “Colorado Airlift”, a magazine-dropping helicopter that landed at the venue.

Other speakers included Glendale Mayor Mike Dunafon, State Sen. Greg Brophy, KHOW Radio Personality Michael Brown, Weld County Sheriff John Cooke and State Sen. Ted Harvey.
