Whats it cost to get a new cylinder made?

I'm just curious, what would a new cylinder cost for say, a gp100? Instead of .357mag/38spl, .38 special only(rated for +p though, of course), and unfluted.
 
I'm guessing about $500 for a cylinder from a gunsmith that has the equipment to do one. Call a couple of smiths that do 5 shot cylinders for Rugers, that will probably be close.

Just curious, but why do you want a 38 spl only cylinder?

Is the unfluted part because you like the way they look?
 
You could contact Ruger and see if they offer that service.
Be prepared to pay handsomely for it too.

Also note that you will be purchasing a cylinder assembly. This will include the cylinder, star-extractor, extractor rod & springs. And you will need to send your gun to the 'smith with your order so the cylinder can be timed to your gun.

What's that? Just swap your old star extractor to the new cylinder?
Repeat after me: Custom fitted precison parts.
Say that 10 times and you'll get the idea.

Fluting is performed to shave weight off the completed gun. Unfluted cylinders are generally used for Magnum pressured guns or when roll-engraving of the cylinder is done for decorative reasons.
 
For what that cylinder would cost you could buy a nice used Smith in 38 special. I looked into a spare cylinder for a ruger single action from one of the after market smiths and was quoted $429 . Ruger factory I dont belive will offer such a service .
 
I could be wrong, but isn't the only difference between a .357 and .38 cylinder the total length? To have a true .38 cylinder, wouldn't you also need a new barrel to correct the cylinder gap?
 
You can find a nice used S&W 686 "hunter" with unfluted cylinder for $400 or so on the used market. Of course you could also just rethink the need for a unfluted cyl unless your pushing the envolope in 357 handloads.

This is why I asked about why he wanted the unfluted. The unfluted cylinder does add weight, it does not add strength. The weak point of a cylinder is the bolt notch on 6 shot guns. It is the thinnest part, and is the point that cylinders let go, and followed shortly therafter by the top of the frame. 5 shot guns (or 7, any uneven number) have the bolt cut offset between the chambers, and this is the greatest advantage strength wise over a regular 6 shot.

After the bolt cuts, the next thinnest part of a cylinder in the wall between the chamber and outside of the cylinder, or on some guns, the wall between chambers.. Fluting or non fluted does not change any of those dimensions.


The chamber length is the only real dimensional difference between 38 spl and 357 guns, tho most 38 spl guns do have shorter cylinders. Not required, but it makes the gun lighter to have the shorter cylinder. an unfluted, shorter cylinder would seem to defeat the purpose of a 38 spl cylinder if weight was the consideration.
