The 50 GI accomplishes all that with the pressure of only 15,000 pounds per square inch. With the 6-inch barrel, especially, it gives much-reduced muzzle blast compared to other powerful defensive chamberings intended to supplant .45 ACP. While the case has a rebated rim like .50 AE, it’s straight rather than tapered. Seven cartridges ﬁt a regular 1911 magazine.
Recoil was the same as with a standard .45 ACP Government model, and the pistol showed impressive practical accuracy. Fired at the rate of about a shot per second, Model 4 gave one inch dispersion at 10 yards with all four loads. The sights as supplied were regulated for 230-grain HP and 300-grain JFP ammunition, with 185-grain HP hitting slightly lower and a 275-grainer an inch higher. At 25 yards, the groups predictably scaled to 2.5 inches, which is quite good for a ﬁghting pistol with iron sights. The combination of plain rear sights and tritium front worked well in moderate light, with the eye focusing on the vial with ease. With the long slide providing a nice forward balance, the sights returned on target readily. Overall weight is only a couple of ounces more than a regular M1911. The pistol is available in a wide variety of ﬁnishes and with various sight options.
Magazines required a good smack to seat on a closed slide when full, and dropped free when empty. The textured slide release worked well, so that I didn’t even bother with dropping the slide with the weak hand. The degree of texturing was sufficient for retention, not enough to abrade the hands. Unlike .357 Coonan, the Model 4 in 50 GI didn’t require conscious wrestling back out of recoil. It shot like any other 1911, with the sole difference of delivering a greater impact downrange. The report was not noticeably different. The muzzle ﬂash was not visible in daylight.
So for the cost of dropping the full capacity from 8+1 to 7+1, it is possible to get a well behaved but more powerful weapon with the familiar form factor. The only down side I found has been the price: the pistol lists for a bit over $4,100, magazines are $50 each, and the ammunition runs $30 to $50 per 20-round box. I plan on talking to a couple of manufacturers to see if cheaper target ammunition may be developed for practice. ASJ
