Noooooooooooo!
And I'm a wild fan of the Security-Six. But I'm also a fan of the 5906, which is one of the all-time greats. True, the gun most likely shoots .357mag, as the CHP most likely reamed the chambers. But the 5906 is an incredible gun. Why get rid of it? If you want a Security-Six, buy a used one.
But first, do you have any photos of your 5906? Is it the latest two-tone model? The 5906 will take 10, 15 and 20-round mags. The Ruger goes six. Do the math. If you need a .357 and can't afford one, get a Taurus. Better to have those than trading for the Ruger.
But don't do that deal. You'll be getting the short end because I think you'll regret it in the long run.
Regarding the .38 Spc version, I bought two Ruger Speed-Sixes and had both reamed. The gunsmith who did it was a stickler for precision. He reamed them so that any .357 JHP would catch in any of the chambers. This has resulted in amazing accuracy for JHP magnums. I had planned on selling both because when I bought them, the .38s were hard to sell. And reaming wasn't that expensive. But once I saw how they performed on the range, I decided to keep them. The guns also had 3-inch barrels, which probably would have made them nice collectors, but if I could do it all over again, I wouldn't change a thing. Those guns are the best bugout bag guns I've ever seen. They also are the best camping and trail guns. The actions on both are incredible, too.
