Fired my M&P (no laser) Bodyguard for the first time with 25 rounds of Prograde ammo a few months back and it worked fine. Fired it for the second time today with the steel cased Tulammo from Wal-Mart and experienced about 10 out of 50 failures to fire which I suspect are light strikes. All the cartridges fired on the second trigger pull. I'm a little concerned now because I usually carry this gun (with quality self-defense HP rounds). The gun is all stock and obviously I'll choose a different brand next time I go ammo shopping. I'm inclined to blame the cheap ammo but I know the Bodyguard has had some problems so I'd appreciate any opinions whether it's the ammo or the gun.
