Well,we all have our beliefs and opinions,and mine do run in favor of the full length guide rod; a spring that is not captured in its side to side play will "bow"and I will freely admit that the functioning or "smootness quotient"that is gained by a guide rod is pretty small,but nonetheless there. As to advantages in recoil control,again the gains are small,but any weight added at the muzzle will help. You mention a 41/4"barrel which is Commander length,so the next bit of info may not be a direct aid,but here goes. Two months ago I installed one of Wilson's full length tungsten guide rods in a full size Service Grade,and I can tell you that 5 ounces out at the muzzle made a BIG difference in double tap training for IDPA matches as it pertains to recovery time;in addition,it gave the piece a weight bias more at the muzzle which I really like personally; the pistol seems to swing smoother during multiple target engagement sort of the same reason many trap shooters prefer muzzle biased shotguns.The bad news on this item is it is pricy and only available for full size 1911's although if you have access to a machine shop,it could be cut to fit. Currently I have another on order for that very reason myself and will E-mail you the results of the fit in my Commander.As for the inability to rack the slide with the muzzle,I can envision no good reason why you would ever need to with a 1911 that functions 100% of the time as you have 7 or 8 rounds and when they are gone the slide is already back waiting for the next mag. With the Tactical reload you still have a live round in the chamber. Hope this is of some help. Regards.
