Beretta makes one heck of a good auto loader too.
customized one for a cop one time.
Very simple to work on and no special tools required.
My number one problem with the Remington is the ejector is/was staked in and it needs a fancy tool to put the other one in.
I have that tool paid for itself many times over and it wasn't cheap.
