Owners of the CMMG Banshee MkG in .45 ACP black finish appreciate the practical look compared to the bronze variants. The 8-inch barrel is longer than a typical .45 ACP handgun, which owners use to their advantage for improved ballistic performance, particularly when running a muzzle device.

Reliability is a common topic. Most owners report smooth cycling once the pistol is broken in, with a minority experiencing feeding issues early on that resolve with round count. The .45 ACP chambering limits magazine compatibility compared to the 9mm Banshee variants.

The black finish on the MkG is seen as durable and conventional. Owners who want a low-profile, functional pistol without the visual statement of a colored finish tend to prefer this version. Build quality is generally praised, with a few owners noting that the price puts it in direct competition with similarly capable options from other makers.
