Came across this used Springfield TRP Operator in 10MM my favorite caliber. This one was different as it was displayed in the case with 5 magazines and all the paperwork/work order from Nighthawk.

I decided to test it with 5 different brands of 10MM magazines and different 10MM ammo. I even put some of my own 10MM SWC Revolver only 10MM reloads through it. I call them revolver only loads because I have never seen a 10MM Semi Auto be able to feed them.

With some Buffalo Bore 220gr and other manufacturers thrown in
