P320 Compact Build Kit with everything included parts wise for the gun. You have to be able to complete the blank for it to be a functioning firearm. Currently it’s just a kit.

Slide assembly can be used on a milled fcu (factory or non factory milled)

The slide price alone would be around 350. The frame mags and case are also basically free if you compare the pricing. 

Brand New planned on building but bought other kits and focused on those.

Jig can be multi use and is a heavy chunk of steel and usually costs $150 alone. 

If it were to be shipped I would have the buyer cover the Collect On Delivery. Collect on delivery is a service USPS does where they drop a package off and collect the money. This is the safest way for both the buyer and seller that I can think of shipping wise.
