Your mileage may vary.
As with everything else on God's Earth.
All I know is that every Glock I own,
Is gonna do what it's intended to do, everytime I pull the trigger.
Until it runs out of ammo.
With any factory mag.
Your not gonna want to hear this.
But get a Glock.
I know.
I fought the ugliness and lack of an external hammer since gen 2s at least.
Till I shot one.
And it eats anything, ammo wise, consistently and pretty much turns steel cases into barbed wire.
Well, maybe I'm stretching that a bit.
