Then what you are saying is not to use anyones 9mm barrel in a 40?

Simply my opinion, I would only use a barrel that was manufactured to be used in place of a 40. Example, Storm\Lake. People I have spoke to directly at S&W have flat out told me not to use their 9mm barrel in the 40 slide.

I'm not so sure sticking your tongue out like this is a kids game is really fitting when one is playing with guns... I'm the first to jump on an easy inexpensive way to achieve a goal, but when we are talking guns, I really want to be 100% certain that what I am doing can not result in an accident. We don't usually get second chances with a gun... I read all the threads about doing this and felt pretty confident it worked and I was ready to jump on this one... but then I was talking this up with one of the range officers at Smith and Wesson, he jumped me pretty hard and said not to. It's close, but the bottom line.... it is not the same barrel. I don't want to be the one that finds out the hard way, it was a mistake, 1500 rounds down the road. I'll spend the extra 70-80 dollars... for that matter, I saw a few SL barrels used for sale. If one wants to save a buck search around, otherwise. I want to stay shooting for a long time. I have my 9c and my 40c sitting disassembled on the table in front of me as I type... the 9 barrel fits in the 40, the slides go back and forth, the springs look the same... but the machining is diff.. it's tempting to shoot it... naaaaa.... think I'll just put everything back the way it's supposed to be and just use my SL barrels..

Whatever.... To each his own. I'm saying people here have done it. If it makes you nervous then don't do it. You think there's a difference in the guns? Or just different barrels? I say it's the barrel. I don't think every gun is made differently. You have them both side by side, tell us the differences between the two receivers.

Factory 9 and 357 fit in a 40. No mag changes are even needed.
Midway lists the barrels for $65, discounts are available.

No spring changes. No slide changes.

Yes, the mags fit the gun, but the 9MM bullets, don't work well in 40 magazines.
I bought the Barrel for less than $60, a factory S&W barrel, @ dealer cost. The 9mm mags were $20 - $25 each, factory mags.
