Working with a combination of new made and extensively modified original Luger components, John Martz produced a variety of custom Luger variants. This pistol combines two of his most famous customizations, being a Luger scaled down to the "Baby" configuration while also upgraded to 45 ACP. Each of these modifications requires radical alteration, the latter requiring the pistol to be widened at multiple locations, and the former dramatically altering the length and height of the pistol without sacrificing the signature look of the piece. Fixed sights, with "J.V. MARTZ 45 ACP" on the underside of the barrel, "MSTR" on the left side rail, and "JVM" and "64" underneath the side plate. The chamber has been marked "41", with a "DWM" toggle. Fitted with a Martz Safe Toggle Release system, smooth bordered "GKS" matching numbered grips, and two specially adjusted Baby 45 ACP magazines.

Very fine as professionally built by John Martz, with 98% plus rust blue finish, showing some light handling marks overall. The grips are also very fine, with crisp checkering. Mechanically excellent.
