Recently taken off my Tm usp, this is the Detonator metal slide and barrel kit for the full sized TM USP.

comes with new style extractor and pin for nozzle spring. Really easy to swap parts over.

These are near impossible to get anymore. There are some wear related marks as shown in the photos but nothing that would be uncommon from use. 
 

It’s mostly been sat on my usp as a wall hangar as I prefer to actually play with my other plastic slide pistols for efficiency.

price includes PayPal payment and postage within UK.

cheers.
