Now do you use these for production or would they be legal for production? For me the 5oz Taylor freelance mag extension would be better adding 6rds. Mostly bc I miss a bunch. But if you could use it in production that would be sweet.
On the M&P for carry optics I believe that grip will add the most weight. I’m not too sure other than that grip a tungsten Guide rod and brass mag extensions another way to add weight to the M&P.
I would be all for it. It’s seems like a lot of us poors are headed in to the carry optics. Half of the shooters at my club are shooting it this year. Far more than open.
