John has the Valtros made to his specs using metal to his specs.
The Valtro weighs 2oz more than a regular 1911 (40 vs 38 oz).
He makes the slide very slightly thicker and beefs up some other parts of the gun.
After taking apart my Colt and my Valtro and seeing how they are made and how they are fitted, I can say there is no way I would buy a Colt and then have it customized. Why pay someone to re-do what Colt could have done a little better in the first place?
I am continually amused by the people who have never seen a Valtro in person, but are still quite sure they know what it is or is not.
The Valtro I bought retailed for $1289 and Most of the Colts on the shelf were pushing high $700s to over $800.
There is just no way you can take a Colt, do the dehorning job and checkering that the Valtro has, debur and smoothe the entire
inside of the gun (The Valtro is smoother on the inside than many guns are on the outside) do the accuracy work, fit the sights, trigger, etc and get it all done for $500-$600. Even if you could do a lot of that, the Colts just are not as strong and I doubt you would get the level of fit and detail of the Valtro.
Trying to make the Colt perform like the Valtro is like trying to make a Civic perform like a Mustang GT. Sure - you can buy the Civic for $8000 less and then dump $8000 into the car to make it "fast" but in the end, you still have a Civic.
The other factor for sven, steve c, myself and many others is that we live in CA. We can only get certain guns that are "approved". That covers over 800 handguns now, and a lot of 1911s, but you cannot go buy a purely custom gun here because it would not be "approved". You can have your gun customized, but a lot of smiths are afraid to do it and those that do it are swamped and the backlog is tremendous.
There are a few guns that can compare and perhaps even surpass the Valtro - a few are available in CA, but all of them cost several hundred dollars more. (Wilson, Baer).
Can you buy a better 1911 than the Valtro? Probably yes.
Can you buy a less expensive 1911 than the Valtro? yes
Can you buy a gun that is as good as a Valtro for ~$1300?
No.
As for the slide drop on empty chamber - I got no dog in that fight, but I have seen Jardines workmanship and knowledge first hand - he guarantees all of his custom guns and his Valtros for life (probably his life) and I would think that if the slide dropping hurt the guns, he would be fixing them and telling people not to do that. I do not do it myself. Oh, and word is that the range in San Rafael has a Valtro with well over 80k rounds through it and all thats been done is new springs and new blueing.
