I would look to a different pistol if one of the first things you want to do is replace the barrel. On the other hand, that pistol is pretty damn nice and I think you will like the way it's configured out of the box.
Guide rod - yes , gun fan gave an option .
If it's a bull barrel and I assume that it is. Buy a 10-8 plug and a Wilson flat wire kit to replace the FLGR.
Are you aware they use it on the Range Officer as well?Uh, it uses the SAME forged LOWER RECEIVER and Match barrel.
Call them and see/hear for self.
No one seems to confuse the Range Officer with a TRP. A TRP is much more than a forged frame and match barrel.The .45ACP Range Officer® has the same quality forged national match frame and slide as the Trophy Match™ and TRP™ 1911s. It gets the same precision fit as these pistols, too. Add in the same match grade stainless steel barrel and bushing, and you have a pistol that shoots well beyond its price tag. - See more at: http://www.springfield-armory.com/products/1911-range-officer-45-acp/#sthash.OrcNynae.dpuf
