I still haven't removed it from the shipping box. I will do an introductory cleanup tomorrow.
What I do know is I was forced to purchase the Red Plastic Jacket model. It was the only type available at purchase.

How do I give it a draw-type magnet test ... with a small screwdriver end perhaps? Their website shows a bare primer breechplug available.
