Cx4 storm is a blast to shoot.Great carbine! The trigger is(was) its only drawback,except for its price, pricey. Trigger never felt solid. I replaced the trigger,hammer and spring with Sierra-Pappa's fix. BIG improvement,now it feels perfect.I also replaced the buffer spring and pad with Sierra-Papps for good measure. Why Beretta chose to use plastic parts on trigger and hammer is beyond me. Cost was probably the reason. To bad, this is its ONLY flaw.
I LOVE the Cx4 Storm 9mm, It performs Very well indeed!
