Nibe at 200 yards you are not going to have a tack driver in your hands. The 9MM bullet has the aeros of a brick. That said, your rounds may not be touching but from a rest a 12" plate should ring loud and clear. While I don't have my Ruger anymore, I do have another carbine where I run the charging handles on both sides. I seldom use the right-side handle, but it is there, and you can't use it if it is not there. BTW my Ruger always locked back after the last round using Glock mags. Mine was the basic model with no aftermarket parts. The latter are nice but I don't think they really are necessary.

Oh for sure, w/o checking a ballistics calc I expect 1-1/12 ft of drop at 200 yds at least. I'm new to carbines so you may be right on the aftermarket parts...anyway love the gun. Fun times.
