Will a KSC 18C threaded barrel fit in my KSC 23F?
 

I want to buy a threaded barrel and silencer to hide the long tightbore in my KSC 23F. There is no such thing as a 23F threaded barrel and the only barrel for the G19 that I can find is the crappy 2 piece G&G one. So I was wondering if anyone knew if an 18C (Guarder) threaded barrel would fit in my KSC 23F?

Thanks
