Beretta CX7 Storm

[22lr]

Barrel contour thin inside frame, heavy outside?

not quite thin - mine is maxed out on the inside but not quite as thick as outer visible portion of it. Limiting factor in making heavy inner part is hole in polimer frame (unless you decide to bore it out) and bolt carrier piece that actually goes around the barrel

I think I am going to go with a light profile barrel even if its less accurate.
