Two main variants can be distinguished, the earlier (1944 model) G1 with a small internally-bolted main gun mantlet and a modified Panther A engine deck, and the later (1945 model) G2 with a larger, externally-bolted mantlet and a modified Panther G engine deck, though late G1s also had a larger mantlet. Early Jagdpanthers had two vision openings for the driver, whereas late versions had only one. The main gun originally had a monobloc gun barrel, but later versions were equipped with the PaK 43/4 gun with a two-part barrel. Early G1s (to September 1944) were given a distinctive pattern of Zimmerit anti-magnetic mine coating.<
A total of 415 Jagdpanthers were produced from January 1944 by three manufacturers; MIAG produced 270 from January 1944 until the end of the war; Maschinenfabrik Niedersachsen-Hannover (MNH) produced 112 from November 1944; Maschinenbau und Bahnbedarf (MBA) produced 37 vehicles from December 1944.
