I own Colt, Kimber and Springfield and still have have owned one truly custom 1911 built from the ground up on a Caspian frame and still have one built from the ground up on a Springfield mil spec frame. I’ve had this one for going on 40 years and had it built before there were many options other than get a gun and totally rebuild it inside and out. I’ve put tens of thousands of major USPSA loads through it and have replaced springs and that’s about it and it’s still shooting great and still tight.
I’ve never shot a bad 1911 but I suspect there have been some. There are so many great 1911’s now I don’t think you can go wrong with whatever you pick. Threats huge differences in a production gun and a real custom gun, one built as one of a kind by a master gunsmith but you’re going to need to sell a kidney to get one and wait for a while to receive it.
I’m happy with my Kimbers and Springfields and have one Colt now. My Colt is a SXE LW Commander in 38 Super and it’s a very nice gun but the chamber isn’t supported and it’s not as nicely finished or as refined as the Kimbers or Springfields. Both Kimber and Springfield make a beautiful and refined gun. Both have great triggers, function reliably and are quite accurate. I have had Kimbers from the Micro 9 up to the 5” Eclipse Target 38 super and Commander and officer sized in between in 45 and 9mm. I still own quite a few. I’ll say my 5” Evlipse Target 38 super is one of the nicest production 1911’s I’ve ever shot. It’s a steel frame throughout with excellent front strap checkering and has a fully supported chamber.
When I bought my Eclipse I was looking for a gun I could shoot 38 Super major loads in. I had 1000 very hot rounds left from USPSA shooting I wanted to shoot up. I contacted Kimber support and asked if the Evlipse would take it and without hesitation they said yes and that they had several competitive shooters using them in 38 super.
I bought one, put a heavier recoil spring unit and a shock buffer and over a couple of weeks shot 1,000 rounds of 38 super consisting of 125 grain jacketed bullets with 540 Winchester powder under them chronographed st over 1400fps. This is 357mag I’m territory and I had absolutely no issues.
I restrung my gun for lighter loads, removed the shock buffer and have shot many thousand additional rounds through it. It’s a great gun!
I’m that pleased with my Springfields. My 9mm is an all stainless with Bomar type Target sights. I can’t say enough about how good the trigger is and how well finished it is. It is accurate and is one of the softest shooting 1911’s I’ve ever owned. Everything is right on that gun.
Saying all that I’m a colt revolver fan and they make fine 1911’s and CZ May have upgraded them some but their 1911’s aren’t as nice and you don’t get as much for your money as you go with some others.
Best thing, look at some and see what flips your switch then buy it. They’re easy to customize, kinda like a Jeep.
