This video compares the velocity loss between ported barrels and compensators on various firearms, as well as the impact of barrel length. The presenter, Mr. Madness, uses a Garmin X1 Pro chronograph to measure the feet per second of 115-grain 9mm Blazer ammunition fired from a CZ Checkmate (5-inch barrel with comp), CZ Shadow 2 (4.9-inch ported barrel), CZ Shadow 2 (4.9-inch factory barrel), CZ PCR (4.9-inch factory barrel), and Glock 43 (3-inch barrel). The tests indicate a slight velocity loss with ported barrels compared to factory barrels and a more noticeable decrease with shorter barrel lengths.
