This is actually rather odd when you think about it - Patton isn't usually associated with the M1911 Auto. He certainly used one in WW1, and also during the WWII 'training' phase.
But once overseas, he favoured a Colt Single Action Army, Smith & Wesson .357 Magnum, plus Colt .32 pocket auto and Model 1908 hammerless .380 ACP auto ( and also, very occasionally, a Remington 1908 Model 51 .380 auto...).
The SAA, S&W and Colt .380 are the weapons which can be seen in most Patton wartime photos - and the early-model S&W .357 was 'two-tone' with blued frame/white cylinder.
Still, for the market this thing is probably targeted ( sorry !
) at, it doesn't matter as long as they spell the name right.......
