Magpul’s new 40-round magazines should prove popular with 3-Gun competitors. The extra 10 rounds can reduce the number of mag changes, which should allow 3-gunners to shave seconds off stage times. As with other latest-generation PMAGs, the new PMAG 40s feature an over-insertion stop catch that prevents the magazine from being slammed too far into the gun during fast changes. This stop catch prevents mag damage and lessens the chance of a malfunction. For LEO and Military personnel using select fire ARs, Magpul notes that: “The optimized magazine spring can handle feeding at cyclic rates over 1150 rounds per minute.”

Major vendors, such as Brownells, will be selling the PMAG 40s very soon. Brownells is charging $19.95 for the PMAG 40, product #100-012-633WB. We expect these things to sell like hotcakes. The editors of Guns.com note: “These magazines are going to be incredibly popular. Everyone likes extra ammo, even when it’s hard to find. And when most magazines with capacities greater than 30 run $40-$50, at these prices Magpul is going to tear through their competition.”
