Just IMO.....
I own all 3 Wilsoin Combat, Colt Officer and Kimber Crimson Carry Ultra and far as I'm concerned, the Wilson is overpriced. I'd sell it but I like to collect, besides you can never have enough......
I'll take the Kimber full size over both the Colt and the Wilson and the Meprolite sights are great as well as the lasergrips.
The Colt is on par with the Kimber in feel and accuracy.
If I was to choose just one, it would be the Kimber for handling, accuracy, weight and value.
I have no problem drilling the bull at 50 feet with any of the 3, it's just the Kimber 'feels' better to me.
Additionally, the Kimber Tac-Mags (which fit all full size 1911's) are better, again IMO than the Wilson mag, cheaper and they give you 3 different base options with each mag and the feed lips are teflon coated. Kimber also has a slick, 30 second install, .22LR conversion for plinking on a budget. I use it all the time. Takes 30 seconds to change out and outwardly, it looks identical to the 45 slide, except the hole in the end is smaller.....
The cheaper 1911 clones like the new Ruger and Para-ordinance, have a steel upper and lower so they are heavy. I prefer the alloy (hard coat rail) lowers. I don't like carrying a tank around.....
