An annoying and generally inappropriate buzzword involving firearms is the word "clone".
Let's define the word properly first, according to Dictionary.com
clone / klohn / n.
a cell, cell product, or organism that is genetically identical to the unit or individual from which it was derived.2. a person or thing that duplicates, imitates, or closely resembles another in appearance, function, performance, or style: All the fashion models seemed to be clones of one another.
a population of identical units, cells, or individuals that derive from the same ancestral line.
Based upon definition 2, any firearm produced after the approved prototype, and to the same design specifications and tolerances, IS A CLONE, regardless of manufacturer as long as the parts from manufacturer A and manufacturer B are interchangeable.
Browning Hi-Power or P-35 or HP-35 or GP (Grande Puissance) is a pistol design. It was conceived by John Browning, and improved/completed by Dieudonné Saive (pronounced Deeyuh-doan Sah-yeeve) in 1934, at Fabrique Nationale, an arms manufacturer in Belgium.
Fegyver- és Gépgyártó Részvénytársaság (Arms and Machine Manufacturing Company) or FEG was an arms manufacturer in Hungary, which, by the way, made excellent weapons and produced a Browning Hi-Power pistol, their designation being the P9. The FEG P9 is a true Browning Hi-Power, all parts being interchangeable with an FN pistol. The FEG P9 BHP was simply manufactured in Hungary instead of at FN in Belgium or Portugal. FEG also had several models of Hi-Power style pistols.
It would therefore be correct to state that, aside from the original completed Hi-Power pistol that Saive made, ALL other pistols manufactured to the exact dimensions and specifications of the Browning/Saive blueprints are, in fact, so-called “clones”. This is true with any mass produced product, the original is the first one, all the rest are, theoretically, identical copies, i.e. clones.
To put it another way, a Model 1911 is a pistol design created by John M. Browning for Colt to manufacture and sell. During WWII not only Colt but Remington Rand, Ithaca Gun Company, Union Switch & Signal, and Singer Sewing Machine Company, all produced 1911(A1*) pistols. These were all true 1911's, and can legitimately be called Browning Model 1911 automatic pistols, in that their parts were interchangeable with the pistols true to the original Browning design.
This can be verified by purchasing the book “Decoding the FÉG Hi-Power” by Jerry Paregien. This is an excellent and highly informative book and well worth the few dollar price.
*Please note that the A1 changes to the original 1911 design consisted of a shorter trigger, cutouts in the frame behind the trigger, an arched mainspring housing, a longer grip safety spur (to prevent hammer bite), a wider front sight, a shortened hammer spur, and simplified grip checkering (eliminating the "Double Diamond" reliefs). There were no significant internal changes made, and parts remained interchangeable between the M1911 and the M1911A1.
