Lol it's ok. I like the opinions. I am learning a lot.
Your CCO is a Commander slide on an Officer frame. Commander length 1911s are not known to be troublesome and usually come with a traditional recoil system like the CCO does. Apples to Oranges comparing a Commander to an Officer recoil system. You obviously aren't that knowledgable about the differences between 1911 models. You should study up more before posting and exposing your ignorance of the topic. Congrats to the OP on his new Kimber. Good luck with it.... you'll need it.
At least your grips will be reliable.
Don't waste your breath on this guy CM, he's just a lot of bad energy. Each of his posts seems to be crafted to generate controversy and I don't imagine any are really legitimate. Even his screen name stands for ruining the ground for those to come later. I'm not sure if he's a past banned member, anti-gunner or what, but his time here has largely been spent trying to stir up negative emotion. I got caught up in it before I realized that he is the worst kind of a troll. I've blocked him and am getting back to the reason we are here.
I'm not seeing anything on the ECO having a better recoil spring setup than Kimber does. My CCO has a short guide rod and standard plug and shipped from the factory with Wolff springs. From what I'm seeing on other forums, Dan Wesson owners are opting for the same spring change interval in their short 1911s as are Kimber owners. If anything, the Kimbers seem to have a bit better engineering in the recoil spring department on the short 1911s, not worse. My Kimber Ultra had dual recoil springs. I don't know why you are so intent on on another users experience, but at least come at it with fact, not folklore.
good you educate me on why you do this?
The DW recoil spring set up is on the top with the Kimbers on bottom, I only switch Commander and Government model recoil springs out personally.
