I doubt hand cycling will help the break-in process a whole lot, but it won't hurt either, although if your dry firing it with a few snap caps in the mag, this will most definately help break in the trigger. Personally, I would just go shoot the thing using cheap hardball. Save the hollowpoint full house loads for carry and an occansional workout at the range.
As far as an upper in .45, again I would just save up a few more bucks and get yourself another pistol.
I reject your reality and substitute my own.
