I've had 1911's with both. I noticed no appreciable difference. The FLGR did not shoot smoother, did not tame recoil to any noticeable degree. It did make the gun a tad bit (couple of ounces) heavier, a consideration if you're gonna carry it. Take down-schmakedown, use the base plate on a magazine to depress the plug and you're golden. It really comes down to preference. Some think it has a benefit, some don't. They ain't real expensive, neither are the spring plugs, buy one of each and try it out. See what you like, or don't.
