I love guide rods. They cost money and are a subject for almost endless discussion.I checkered the end of the one in EAGLE1. I do not like them in Commanders, but do not have any valid reason for this.I love shockbuffs but do not like them in Commanders because I feel they limit the already short slide travel.Reverse plugs are indeed for bull barrels and they can be alot of fun.It is an easy recoil system to remove but has to be installed with care. I view commander size 1911's as carry guns and like them pretty much stock.7 yards ,boom, fall down, and don't get up.I carry a 1954 Colt LW Commander.
