This topic, much like the FLGR or not topic, is one about which people feel very strongly. So do we use buffs or not? I had used them extensively on IPSC guns with good success, and stopped doing so when several lightened slide guns wouldn't run with the shortened recoil stroke. I had become of the opinion that a "real world working gun" should not have a frangible doodad in it. After seeing a number of cracked frames recently, I started wondering. After consulting with a number of smiths whom I respect greatly, and finding that they all used buffs in their guns, I changed my tune. The good word is that buffs do indeed work as advertised, but make sure that your gun will RUN with them in place. My primary gun will run and lock back properly with them, so my old supply of CP Buffs is back on duty. Keeping fresh recoil springs in the gun doesn't hurt either. And no, I'm not worried that a ripped buff will tie up my gun. Doom on me if I'm so negligent that I don't maintain my weapon on a regular basis.
