I bought a 360PD through the net, and it is at my local gunshop. The lock up is not very tight, but not horrid. Then I looked at the forcing cone, which is very bright, and looks like bare aluminum, which did not seem right. I did not bring a gauge to measure the gap.

All my other S&W are steel.
What should a forcing cone look like on a 360PD?

thank you

The barrel on your 360, including it's forcing cone is stainless steel

Is the forcing cone that you are comparing it to carbon steel or stainless steel?

The shroud that surrounds your 360's barrel is an aluminium alloy

Never heard of an aluminum forcing cone. I doubt an aluminum forcing cone would make it through a single box of ammo.

The foreign cone surface does not look like smooth stainless (like on my 686). I would not thing aluminum could survive. But much of this is alloys of scandium, so I don't know.

The actual barrel and the forcing cone portion of it are steel, the shroud that covers the barrel and the frame are Aluminum/scandium alloy.
