Hey all, I had a Wolff 18# mainspring in my 1911 (fullsize Springfield Loaded with Ed Brown MSH) and after around, or even less than, 1K rounds I started having light strikes--first only with WLP primers but then soon with CCIs also. I know that it's a light spring weight from the Gold Cup, and yes, I was doing a lot of dry-firing when that one was in there. I threw the mainspring in the trash and started using the factory one from the ILS MSH again, which I believe is 21#, and the pistol has been up and running again for about 300 rounds. However, the current/original mainspring now has a significantly reduced pull weight in comparison to where is was less than 500 actuations ago. Does my 1911 just eat mainsprings, or is this normal for the platform that they need replacement every 2K? Is it possible the stock Loaded MIM mainspring is just that much lighter than the Gold Cup's? I've put thousands of rounds through other platforms like the HK P-Series and their mainsprings ("Hammersprings") never need attention. Wanna kill these ads? We can help!
