trigger pull is ≥ . One notable design flaw was the leaf spring that powered the ejector, which could break off and render the ejector inoperable. A combat-expedient repair method was to slip a bit of rubber under the bolt stop spring. A redesigned ejector, incorporating a small coil spring in place of the fragile leaf spring, was developed and can be fitted to the M1917 to remedy this issue. The M1917 was well-suited to the rimless .30-06 Springfield round which came closer in overall length and muzzle energy to the original .276 Enfield high-velocity round for which the rifle had been designed than the rimmed, less powerful .303 British round of the P14. The M1917's barrel had a 1 in 10 in (254 mm) twist rate and retained the 5-groove left hand twist Enfield-type rifling of the P14, in contrast to the 4-groove right hand twist rifling of the M1903 Springfield and other US designed arms. The M1917 had a long 26-inch heavyweight barrel compared to the lighter 24-inch barrel of the M1903 Springfield. With the longer sighting plane, the M1917 proved generally more accurate at long distances than the M1903, at the expense of greater weight. The M1917 weighed empty – the M1903 Springfield weighed empty – and a rifle with sling, oiler, and fixed bayonet weighed over . The M1917's long barrel and issued blade bayonet proved too lengthy and cumbersome for trench fighting, while its weight and overall length made the rifle difficult to use for some smaller-statured soldiers. During World War I the average height of United States soldiers was . Many M1917 Enfield rifles were refurbished during World War II with newly manufactured High Standard barrels with 4-groove rifling and Johnson Automatics barrels which had 2-groove rifling. Variants The M1917 action made from nickel-steel proved very strong, and was used as the basis for a variety of commercial and gunsmith-made sporting rifles in standard and magnum calibers between the world wars and after. Later, Remington Arms redesigned the M1917, removing the "ears" and changing it to cock-on-open, to become the Remington Model 30 series of rifles in the interwar period, which were produced from leftover receivers and barrels. During the Great Depression Model 30s weren't selling well, and the company decided to develop a M1917 derivative targeted to Central and South American militaries. This found only one buyer in Honduras, where strongman general T.
