Dont know, just remember it from the first season of Miami Vice. Seemed pretty cool at the time. Then he went to the 45.

I know this sounds unAmerican but I slightly prefer the Sig p220 to the 1911.

Made a little more progress on the 10mm carbine, got the recoil parts in, barrel and handguard blasted ready for Cerakote tomorrow maybe.

Lots of mass in the ass and a Sprinco red

14oz buffer? Why?

Straight blowback operation, no lock or delay. We run around 10oz behind the 40’s so see how this works. Using the AR10 length recoil tube which allows a custom length buffer and 5 tungsten weights. Yee Haw.

Went long on 304 on an ebay auction.
One of the buffers I run in the 40.

I don’t shoot anything in the city that may cause a pass though and hurt an innocent.
Bear country; 10mm.

You do know a 9mm will pass through more layers of drywall then an AR15?
Or are you talking about passing through the perp?
