Tokyo Marui released the Detonics .45 Combat Master Stainless Steel Model last 26 May 2017. This is based on the "MK V" with matte stainless steel finish. It has a dedicated blowback engine as the pistol is a very compact one, uses the D-type piston cup and even if it's palm-sized, you can really feel the recoil effect. It adopts a cone shaped outer barrel as done by Detonics Inc. and dual recoil springs.

The rubber coating has an anti-slip feature and the chambered magazine inlet makes magazine chance easier. The trigger, hammer, and outer barrel are hard plated for scratch resistance.
