My Remington R1 Hunter Longslide in 10mm has a too light factory recoil spring. When I shoot the gun, the brass is slung about 20 feet to my 4 o'clock, even with FBI 10mm loads like Armscor and Magtech. I'm hitting people sitting down at the other end of the range with ejected brass. I'm beginning to get seriously worried that this will crack my frame in the long-run, so I want to fix the problem now. I've looked everywhere on the internet and I can't find an aftermarket flat recoil spring for a 6" longslide 1911. I've read that I can install a modified recoil spring plug from Fusion firearms so that I could then use 5" flat recoil springs like from Wilson combat. Is that true? If not, where can I get a 6" recoil spring? I looked at fusion firearms, and even though they're saying they offer 25 and 26 lb springs, their drop-down menu only lists 23 lbs as the heaviest, and the description says 5" 6". How could a spring be used for both lengths? Not understanding. please help, this is my first 1911.
