New "S70" Colt 1911, anything needed?

[Dantankerous]

Having not been paying attention to 1911s for a few years I've noticed sometime recently that Colt has brought back out their "series 70" guns. The 1911 Classic Government with typical fixed sights. Yeah, I know there is no collet bushing on these but the action is no longer a series 80... anyway. Blued or stainless, I have seen each and they are fairly tight and solidly built guns. Has anyone had any experience with these and might have a suggestion for a tweak or two IF EVEN NEEDED to have these running well enough for competition? Reliability is my main concern. I shoot Traditional, generally with 230 grain ammo although I've had a few suggest 200 grain and am looking at trying that. Thanks!
