I recently bought a SW revolver. I was told that it was a SW M&P, converted to .38 Special from .38 S&W. Apparently these are pretty common. While I was in the gun shop I asked about the caliber conversion, both guys at the counter said 38 Spc and 38 S&W are THE SAME.....

I looked into the cylinder, which has a "ring" that looks like it was reamed out and the barrel clearly says "38 S&W CTD" NOT special. The guy at the counter put a 38 Spc round in the chamber, which fit perfectly.

I have pics which I will post later, but the s/n are 688XX on the butt and barrel and a different s/n on the frame, I dont recall the numbers. Will this tell me more about the gun?

So I am getting conflicting information, what 38 do I use?

.38 s&w special and .38 s&w are not the same It would be a good idea to take to gun smith and have checked to make sure it safe to fire and to find out wich it is chambered in.

the .38 S&W is a shorter and fatter cartidge than the .38 spl

you could ream out a .38 S&W to accept the longer case, but the chamber would still be unusually generous

yup that's the old M&P (pre-M10) with the older "long" action

looks like it's been refinished too, so it wouldn't surprise me if it was re-chambered...if you're lucky, they fitted a new cylinder

9mm, will it shoot 38 spc safely? (that is if it has been re-chambered) I heard that the converted guns arent accurate and that the casings crack inside the larger diameter chamber.

i wouldn't do it...cracked casings isn't a good thing
