I need help in re: Shokbuff/guide rod choice for my new (coming this week) CQB Compact. If it comes with the plastic guide rod that is disposable which metal guide rod should I use for greater reliability? Reduction in recoil forces on the frame is great, but a defensive pistol must be reliable when needed. With the Commander size pistol and its' shorter cycle stroke is a shokbuff using up needed cycle time which might lead to a malfunction? Shoul one do without the buff? Any info would be greatly appreciated.
