I guess was assuming it possibly couldn't handle it only because it doesn't say .38 spl+P on the barrel of the K-frame like it does on my little J-frame. I know that doesn't necessarily mean anything, but I was just assuming that might be the case. I can also only assume that S&W used the same quality stainless steel in the cylinder of both guns that were made probably around 20 years apart. I'm don't know much about this, of course, which is why I'm here to learn. Thanks!
