If you find yourself in a situation where you can’t get new springs, the new system might be a benefit. So what is the advantage if any of the Dual Spring Assembly? If you shoot 8000 rounds a year, the new springs mean 1 spring change a year. We noted no difference in the force required to rack the slide on either pistol with either spring assembly. The spring system dropped in to both pistols as would be expected.īoth pistols normally run Wolff 18lb. There was no additional wear to either pistol.
The pistols did not seem to shoot any “softer”, however felt recoil is a subjective thing. Neither I nor my fellow testers found any difference in the function or felt recoil of either pistol during testing. The pistols both functioned normally with the Dual Recoil Spring Assembly installed. Testing began with the ball ammunition and ended with the reloads. Prior to testing, both pistols were cleaned and lubed as normal. 45 ACP through 2 pistols is hardly a torture test, ammunition cost and supply had to be taken into consideration. An additional 300 rounds consisting of the same ammunition were fired in a Les Baer TRS 1911. The assorted 300 rounds were fired in my Springfield 1911 pictured above. Testing consisted of 100 rounds of PMC 230gr.
I have no idea if Colt intends to develop the system for smaller pistols. It will not fit a Commander or smaller size pistol. The system is designed to drop into a 5in. Springfield 1911/Colt M45 Dual Recoil Spring Assembly
