Re: walther p22 5-inch with threading?
I have both barrels.
It's not the barrel on these that is threaded. There is a nut on the end that tightens to hold either barrel in place and the "threading" is an option piece to screw on the end to hold the barrel in place and has threads that LOOK like they are the end of the barrel. This is what you screw a "silensor" on to and yes it is used on either length barrel.
Send all those Vegans back to Vega if they don't like it!
Who invited them to this planet any way?
