I'd say save your money. Do you have a FLGR set up now? If you're wondering if the buffs help, I'll send you one for free to try out. Shooting the same gun back to back, on a FLGR set up, one can not tell the difference with the buffs.
What the buffs will do over time, is come apart and jam something. Have you ever heard of a 1911 frame wearing out there?
