US standard sidearm at that time was the M1911A1 Colt .45. Longarms would have primarily been the M-1 Garand, with a sprinkling of M-1 Carbines. BAR would also have been around.
thanks.. just thinking of trying to get a full set, since i have the clothing already... i'm sure now a days the m1 would be tough to get.
At the ranges that WWII infantry combat was often conducted, a pistol was, for the most part, useless, so infantry were not routinely issued a sidearms such as the 1911. Infantry company-grade and lower end field-grade officers more often than not carried a carbine, as it made them more inconspicuous and less likely to be identified as an officer and intentionally targeted. It was not uncommon to find company-grade officers carrying a Garand. Look at photos of soldiers from the era. Excluding MPs, rear echelon clerical soldiers and senior officers, you will find few, if any, with a pistol attached to their belts. Even the MPs would probably have a carbine instead of a pistol while in areas that they might encounter enemy soldiers. To give you some idea, the 1944 TO&E for an infantry battalion authorized a grand total of 81 M1911 pistols. An infantry battalion was around 867 men. They were more carbines made than Garands, by a factor of about 50%. Garands can be found: How to Buy an M1 Garand from the Civilian Marksmanship Program – CMP Rifle Sales
