I had two guns with the same problem impossible to get the barrel nut off. I used the EWK tool referred in earlier post with a socket and hammer drill.Works like a champ
good luck

How long had it been since you'd had the barrels off prior to getting stuck. Just wondering if taking the barrel off every other range trip would help prevent if getting stuck.

I suspect virtually every stuck nut is the condition when the gun is obtained. Once you clean a newly obtained gun it should not stick again. I clean the threads of barrel, nut and frame with oil and a brass brush. Flitz works wonders if there is corrosion. If you Flitz, wipe off and oil well. When screwing in the barrel, screw it to the end of the threads and back out. Ditto with the nut. That clears the threads the whole length. And yes, I would remove the barrel and clean after every range trip. Never overtighten the nut. Snug is all that is necessary.
 Some folks that shot Silhouette would loctite the nut on after discovering the degree of tightness that produced the best accuracy. It is like tuning a guitar string for the best sound. I am not good enough of a shooter for that to matter. A top silhouette shooter would shoot 1000 rounds a week or more. After a year they sold the gun and got a new one.
 A S&W is good for about 30k rounds before the frame stretches., Dan Wessons probably are good for at least double that. Also, the barrel tubes can be replaced easily. (unless loctited). Manurhin MR 73 can shoot several hundred thousand rounds with no decrease in accuracy or barrel wear. They were forged out of artillery grade steel and the barrels were cold hammered., leading to a hard bore as slick as glass. Manurhin also made guns with Dan Wesson style barrel and shroud and with interchangable calibers too. Something Dan Wesson could have done but didn't want the liability.Â
That great info!!
