Well after talking about doing it for the past 5 years I finally decided to bite the bullet and have David Clements make me a 10mm. The friend I have been talking about it with decided to do it too. We ordered a couple of Ruger GP100 .38 Spcls in stainless steel with a 3 inch barrel and adjustable sights. As soon as they arrived we sent them strait Clements for his 10mm conversion and slab sided barrel. When the come back in 12 months or so they will look like this:

In the mean time I found a S&W Model 610 with 5 inch barrel and wood combat grips. Life is good in the 10mm world

I would not build a 10mm using a .38 Spl frame. However, I have never seen a Ruger GP100 chambered in .38 Spl.

I've seen them, though I think they are uncommom. Perhaps they have a smaller cylinder window? That would be an advantage I guess for the shorter 10mm cartridge maybe?
 
I've never understood the draw of 10mm in a revolver. Why not run .357? I guess what I'm asking is what is the advantage of 10mm over .357 Mag in a revolver platform? I can see disadvantages in ammo cost and availability. I guess you could run .40 S&W for a cheaper alternative.
 
If you ever decide to sell, the S&W 610 will sell in no time, and will be worth about twice what the converted Ruger will be...

Everyone has a double action revolver in .357. Not many have one in 10mm. It's about having something cool or different, not necessarily more practical.

I wouldn't be surprised if the OP reloads too, which reduces the cost/availability aspect. There's very little fired 10mm brass available. The only caliber I know of where it's easier to find new brass than once fired or range pickup which makes me think the majority of 10mm shooters hold onto their brass.
 
I'll agree with the "cool and different". Moon Clips are nice. Don't get me wrong, I love 10mm and shoot it myself. Just never understood the draw for a wheel gun in a caliber designed to give an auto loader wheel gun performance.
 
Not something on my "Must Have", but the 10mm. conversion of the GP100 does make for an interesting and decent looking revolver.
 
I had my 10MM conversion done on a 1965 Ruger BH 4 5/8" 357MAG by Hamilton Bowen at least twenty years ago now [ 30 years.?]. The BBL was re-bored to 40caliber and the cylinder re-bored and re-chambered to 10MM AUTO. It is rifle accurate out to 200 meters
And by the way , the original cartridge name was 10MM NORMA.
And so it goes...
 
As a 10mm reloader, I appreciate being able to have a revolver in the caliber to compare chrony results vs when fired out of a semi-auto. As a 10mm nut, it is just nice to acquire one of each sample manufactured. Try that with 1911 .45ACP... Plus there's the quazi-useful ability to fire .40S&W in the 10mm revolver, same as .38 Special/.357 Mag, .44 Special/.44 Mag, etc.

Although Ruger are well made, my collection sticks to factory 10mm offerings. Like how about a Colt Double Eagle blued frame, stainless slide 10mm w/ factory .40S&W conversion...
 
One advantage of 10mm is the size of the hole it makes and the weight of the bullet making it -- .40 and 180 grains vs .357 and 158. In a compact revolver, top-end velocity is about equal.
 
You can use 10mm in moon clips and 10mm is more powerful than .357 magnum by a small amount.

Actually the 357 Magnum is more powerful than the 10mm, but don't feel bad this is a common misconception. The 10mm has reached near mythical and unrealistic status ever since it was first chambered in a Glock.
 
Let's not start that debate again. We'll end up with four pages of cherry picked loads that support either side and drift away from the OP's really cool and nice looking pistols
 
Agreed. I REALLY want one of those 5" Model 610s. Sorry I took the caliber-contest bait.
 
Nice looking 10mm's! Never knew you could convert a 10mm from a GP-100 38 special. Learn something new every day.

LOL
 
The 10mm is great fun. I have a bucket list item to get my 610 punched out to 10mm mag. I also am lucky enough to have a 310NG. Not rare by any means I'm sure but I'm pretty sure it's discontinued.

I have one of those 310NG's also. It's a cool gun. It can be a handful to shoot.
 
Great looking revolvers there. One of my favorites is this Blackhawk in 10mm/38-40. Very accurate with a power edge over the 357 mag.

Many 10mm bullets are too tender for higher velocities but I'm pretty sure a 220gr at 1200fps beats any .357 load possible.
