Well, I completely forgot about this post from a couple of years ago.
Alan made this revolver for me about 8 years ago.
I do not remember the exact cost but I believe it was around 1200.00 ?? But may have been around 850.00??
Alan is about ready to retire and only does projects for some of his old customers as I understand it these days..
There are several good six-gun Smiths out there that could do this type of a project though.
Just google Single-Action forums to find ideas on gunsmiths etc.
I still have the gun but do not shoot it as often as I should.
I am currently having Coonan arms build me one of there 1911 Hybrids in 10mm and expect to get back "into" the 10mm this year.

 From Alan Harton.

This is an Old Model 357 Magnum that I had Alan Harton in Texas convert to 10mm. It shoots as good as it looks!

That RZ 10 was probably about 2010?

  Just fired my new Kimber Eclipse Custom two and low and behold it works!. I fired 50 rounds of my own hand loaded ammo using 7.0 grs of Auto Comp and a 180 grain commercial cast RNFP. This is the same bullet one would shoot in a 38-40 revolver and I have found that in numerous 40 cal pistols it always feeds well.
My last 1911 in 10mm was a Dan Wesson Razorback and as much as I liked the pistol, it proved to be a jam-a-matic and was sold at a great loss. That is why I was a little apprehensive about laying out the big bucks for yet another 10mm Model 1911. I can tell this pistol is a shooter! No problems encountered except when I tried one magazine from another Mfg. (Tripp) and had one premature slide lock. That magazine was retired and the factory magazine and pistol were flawless. Shooting nice round groups at 12 paces with a two hand hold, standing. I still have plenty of brass from prior pistols including a Glock 20 that would not feed well with a Lone Wolf barrel and was also sold.
Hopefully this one is going to stay around a long, long time.
This is my first post here but I will post more later as I shoot the pistol over the coming months.
