They really dropped the ball on this if you ask me. They had a chance to redesign the trigger and didn't. But ok that could be a headache. But then they could have made 4 of the compliant parts the trigger. Along with the grip and muzzle device, you have parts that will always keep you in compliance. But no, they had to be cheap and greedy.
Cheap because making the follower and base plate is probably cheaper coming from a mold than finish machining small metal parts to tolerance.
Greedy, because those cheap to make mag parts will be needed for each mag you own. They know they can sell everyone multiples. It's really sh!tty and penalizes those who spend more money buying magazines.
Really sours me further especially after their laissez faire attitude about their website crashing when they were selling the magazines.
So I have a muzzle device, someone may develop a better trigger, and they are saying parts will be for sale individually so a grip could be purchased separately.
I'll just do it myself. Thanks CZ USA.
