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. ---

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. ![2021-10-26 10.13.05](https://sixguns.com/uploads/default/original/2X/c/c3fd44ecb2c5544502f48c62d3d0b3d8fe3ecb9e.jpeg) ![Lathe](https://sixguns.com/uploads/default/original/2X/1/15a04387c0a1c363d09672640efb2d801a42a886.jpeg) ![Buffers6](https://sixguns.com/uploads/default/original/2X/e/eef6f5723ed633ece2b615c5cd9d74307638153d.jpeg) ---

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? ---
