A PRACTICAL SURVIVAL "JBAPON FOR AVIATORS FORCED VOm OF LAND OR SEA. 
This^Carbine P.istol Caliber 30 Ml (fig. 1), consists of a .45 automatic Colt 
Pistol with barrel and extractor replaced by a modified carbine barrel (fig. 2) at' 
a modified extractor (fig. 3). The converted pistol uses both ball and shot ammu¬ 
nition, singly loaded into the chamber. 
The conversion barrel is modified internally by almost completely (90^4*) smoot 
boring the standard carbine Caliber 3^ Ml barrel, and externally by machining it tc 
work in the #45 automatic Colt Pistol action. A sample is submitted herewith#. 
The extractor is modified terminally to permit it to reach far enough centrally 
to extract the 30 Ml cases, as per the sample submitted# 
The Carbine Pistol, Caliber 3° Ml has been invented, developed, and completely 
tec ted under target and jungle (survival) conditions by the undersigned at this 
lco-;lity# m all target tests this gun was fired as a target pistol, standing, 
witnout rests# Test groups of 10 rounds of Ball ammunition at 50 ft. range wore a 1 
close as 3i inches (fig. 6). Samples of the game killing shot patterns thrown by 
this pistol at 50 ft* are shown in figures 7 to 11, inclusive. Figures 6 to 11 ar; 
sl eets of typewriter paper 8 x 10l inches in size personally used as a standard fc: 
sapling the central density of the shot pattern of 32 Caliber (30 Ml) shotguns* 
This weapon is capable ofj 
a. The shooting of small game for food at an effective range of 50 ft. with 
#8 chilled shot in shot cartric' - 3. 
b* The positive killing of any and all (poisonous) snakes at a range of 25 
ft., with #8 chilled shot in shot cartridges# 
£. The shooting of large game at an effective range up to 150 yds with Ball 
Ammunition. 
d, Effective short range combat, up to 150 yds., with Ball Ammunition. 
These four objective functions of a survival firearm are accomplished without 
change of the weapon, used as a single shot pistol, by selection of the cartridge 
to fit the target at hand# 
This Carbine Pistol, Caliber 30 Ml, is at least four times as efficient as a 
survival weapon as is the unmodified #45 Automatic Colt Pistol. 
a. Accuracy of fire with Ball Ammunition is greater at all ranges up to 
' 150 yds, 
b. Effective range of the shot cartridges is doubled, to a practical jungle 
~ range of 50 ft. 
c# Each round of ammunition weighs approximately half as much; twice as 
many rounds may be carried without any increase in weight#
