Hey everyone,

I'm looking into getting the Clements GP100 10mm conversion and wanted to get everyones feedback about it from the forum. I know a few of you have had this done and want to know how everything is holding up, how the guns are being used, how accurate they are, are there any restrictions? Do the moon clips work with both 40 & 10mm or are different ones used? Was it worth it? What barrel length was used, did you have any other mods done while at the shop? Any imput would be great.

Thanks,
Ron
 
This may sound stupid, and I mean no harm in asking this, but why would you want to convert a perfectly good GP100 in .357 magnum to a 10mm. How about just getting a Redhawk in .44 magnum.
 
Clements converted my 686 into a .41 spl. If you have to ask why, you wouldn't understand. Mr Clements is a gentleman of the first order, and if he under takes a job it will be first rate. I am VERY HAPPY with my custom handgun, and would reccommend Mr Clements very highly. Rocky Rabb will second my opinion, ask him.................................................
 
Being able to run the full line of 40 S&W and 10mm ammo in a slick double action with quick moonclip reload capability would be a big seller.
Smith & Wesson Nightguard should be having good sales but the price is pretty steep.
if Ruger were to hit the market with a 40/10mm GP, unless they really do a good job of making it available in the dealers cases and have good factory QC on the function for a good price, it will not be profitable.
After seeing how bad Ruger has done with getting 1911 and other firearms in the dealer's inventories, should never be a problem.

Hamilton Bowen suposedly was quoted that as slick as a 10mm GP is, it took too many hours of shop time to make it work right

I just checked Gunbroker for a 10mm S&W Nightguard and the only one on there as $1200 buy it now
 
I just sold my 610-3 to get this done. The wait time has me kind of shy but it's not holding me back. Figure by the time I get it back, I'll have forgotten I sent it off! :D
 
Hi everyone,

Big Stu to anwser your question, I already have 6 357's and dont req another, I am looking for something that is different/custom. I know the first anwser for most people is "just get a s&w 610" but for the price, I can get a custom gun and have something without the dam lock! I also already have 45lc/acp & 44mag/spl & a 41mag so its not for big thumping, I also thought about the S&W NG in 10mm/40 but it is just as costly as the 610 and I cant say for sure how well it will hold up. Chris_ I to am looking at the turn around time but I'm with you,, I will be sitting at home one day next year and get a cool gun delivered out of no where. I also am looking at selling my redhawk 5 1/2 41mag to help fund this project, I bought it before I went "out of town" for work and the more I think about it, I'm not really interested in getting into another caliber ( I already reload for 10/40) So off to GB it goes when I get back in a few weeks. Thanks everyone for your input so far and hoping some of you with the gun already done can fill in a few anwsers to some of the questions I had.

Agree with dixie. I have four and waiting for the fifth from David. You will be completely satisfied with any of his work. My next will be a Model 28 converted to a 44 spc.

Why not just buy a model 24? Or 624? I happen to have a 624 listed on gunbroker that is in next to new condition for a lot less money than a conversion would be.

Cause its a Smith. :D

Dixie answered that also, "if you have to ask why, you wouldn't understand." :D

Oh I can completely understand getting a conversion done to end up with a gun/caliber that you can't buy, but you are saying that you would have a model 28 (Smith?) converted to .44 Sp.

You can already buy a .44 Special in an N framed Smith, so what is the point in that?
 
I know I'm dragging up my old thread but I have this back in my head, any body get a Ruger 10mm GP100 in the last few months?
 
I have a 3" GP100 that I've been waffling about doing this conversion to 10mm. Out of a SHORT barrel snubbie, would I gain any ballistic advantage with Double Tap or Buffalo Bore heavy 10mm vs heavy 357 mag as a woods gun?
 
Was not laughing..... I have a version of it too. I just don't have the money to create custom made guns to replicate available guns. It amazes me to modify a model 28 to a model 24. I could have understood it when there were no 44 specials around; but not now.

Don't get me wrong, I don't OBJECT to it or anything. It is your money and gun and your business. I just don't understand it. And my illness if I had that kind of extra money would be to buy up the same amount of money worth of classic model 27s or 28s and watch them go up in value.

I understand the custom gun idea, but just to create something that does not otherwise exist.

It is a free world and the gunsmiths need the money.
 
My reason for the GP100 conversion is that I love 10mm autos and have several.

N-frame 610's are too large for me to shoot comfortably. But I'd love to own a 10mm revolver. The GP100 is about L-frame size and that's a comfortable size for my short trigger reach. That's MY reason for the conversion -- and I'm sticking to it! :P
 
I'm missed something . Why a 10MM revolver when there is 10MM bottom feeders for fast reloading , and 41 mag and 38-40 already in revolvers which will the same job and a bunch cheaper that a custom gun .
 
Have a 3-inch S&W 686 .41Special conversion done by Bowen and love it. It's my third .41Special. One is a .357 FT with 4 digit SN, one is an anniiversary .357FT, and then there's the S&W 686. Wish Dixie had some more properly headstamped brass to get rid of now.

I can't speak for others, but as for me, the reason would be to have a carry gun in a revolver that would equal the ballistics of the .45 ACP in a frame that is smaller than that necessary for the venerable .45 ACP.

In an L frame or the GP100, the 10MM would fit nicely and be capable of full bore 10MM Auto loads and would be more easily concealed than an N frame gun.

I would opt for a fixed sight GP in 10MM with a 3" barrel and the hammer spur removed. I think it would be an excellent carry piece with a couple of extra moon clips instead of speed loaders.

And yes, I do have a 38/40 10MM convertible with a 6-1/2" barrel, but it is just not suitable for concealed carry. 8)

If you have to ask why, you wouldn't understand.

I sent my 4" GP to David back in November. I intend to shoot mine in USPSA/IPSC competition.
 
I sent my 3" Gp-100 stainless, 1/2 lug, to David in March of 2010. It was first intended to be a 10mm but I subsequently changed my mind to a 44 spec.

I am still waiting for it...

I shot every kind pistol matches with wheel guns and bottom feeders since 1968 and was always one of the top shooter and held alot of club records . I been a gunsmith and built 90% of my match guns and I don't see or understand why a 10MM wheel gun is needed . When a box stock bottom feeded in 10MM will beat you or 41 mag down loaded to 10MM spec and save $1500 ...

" I don't see or understand why a 10MM wheel gun is needed." Need is never a part of a gun purchase :) weather for fun or a match.

Who wants a bottom feeder???

The .41Mag doesn't fit in a six shot GP.

A GP needs only a rechambering ($150-$200) and reboring (another $150-$200) to become a 10mm. Which ain't $1500. Clements full package is $625-$675.

His big five-shot .44Spl package is only $1200.

Some of us want what we want because we want it and can't buy it. Saving money doesn't enter into the equation.
