I didn't know whether to post in XD or 1911, so I'm splitting the difference and going here. I've got a Springfield XDm-45 with no problems. The only failure I ever have is clearing the gun. I remove the mag and then rack the slide to eject the cartridge in the chamber, and sometimes that round gets stuck halfway out. I've concluded that it happens because of my not pulling the slide fast enough and hard enough. And that brings me to my question. When I bought the XDm, I noticed that the recoil spring seemed really stiff compared to the other gun I almost bought, a Glock 21. Since then, I've acquired a new Colt XSE 01980, which is of course, a 1911 pistol. The recoil spring on that pistol is also much easier than the XDm. I know spring resistance is measured in pounds, but that's all I know. I don't know if 18 lbs is fully compressed, normal storage compression, or what. I've searched a couple of XD/XDM forums, and it seems that quite a few others have pondered this matter and more specifically inquired about softer recoil springs. What I haven't found is anyone who has changed their XDm recoil spring and reported back. I also haven't been able to find an explanation as to why a 1911 or Glock recoil spring can be so much softer, yet be just as reliable as the stiff XDm spring. Does anyone have any knowledge about this, or can refer me to another source of info? Thanks.
