I suppose I could if I could get a dollar bill to stay sideways with any sort of repeatability... kinda like my statement...

Fine...
Try taking a 40 or 357Sig (which use the same breech face) to using a 9mm bullet. And when the weapon won't cycle with repeatability, or blows up in your face.. you can tell me, if you can still speak.

You may very well be getting good repeatability out of yours, but every "presto-chango" barrel swap deal I've read about specifically states that extraction may present problems. I'll have to find one and scan it in if you want proof of that too. It's quite possible that the extractor will do it's job, but I sure as hell wouldn't count on it to function on a defensive pistol. Besides, I'd say practice with what you carry, or you're just burning powder. If you're trying to find a cheaper way to become proficient with your carry weapon, switch to bulk ammo in the same caliber, as shooting high quality defense loads can be expensive, but switching to a .22 conversion kit or even a 9mm conversion kit and practicing defensive shooting when you'll be normally carrying a .357 Sig, well, you aren't going to shoot them the same.:watching:

I bought the 9mm conversion barrel to shoot USPSA Production. I practice with the .40 S&W barrel every time to go to the range for practice. practice week hand shooting, clearing jams, failure drills ect.

Still, for defensive purposes, I practice more the my P239 and M&Pc both in .40 S&W.

For competition, I am going to 9mm.

I buy bulk ammo all the time. It does help, but I really need to start reloading.

How many rounds should I be able to shoot in my 9mm conversion barrel before I can claim "repeatability"?

I'm not quite sure if you are just trying to "bait" me into an argument or not, but if indeed you are, sorry, you won't get me into this type of silly debate that can't be proven either way. It's like saying that you can dig a hole with a spoon. Sure, you can, but a shovel is best, that's what its intented use was. If you want a 9mm, buy a 9mm, if you want a 40, buy a 40. I just don't see the point in using something in a way that it was not originally designed for.

Can the extractor pull the case out? Sure.
Can the extractor have problems doing so? Sure.
Can it function flawlessly? Sure.
Can it fail at any moment? Sure.

You see, the point is, there's no way to "win" an argument like this. I was simply pointing out to the original poster that case heads are different sizes, and there is a drastic potential for problems. Just because something can be done, doesn't mean it's the best solution. Spending close to $300 for a "semi-drop in barrel" seems a bit silly to me. You could simply save up for a couple more months and buy a whole new pistol in a different caliber. No need for troubleshooting, no need to worry if it'll work every time as intended, no need to keep parts straight. Just pick up the 9mm and load her up for a fun shooting session.

If indeed you are not trying to "bait" me into an argument, then please accept my apologies, and also please accept my retraction of the "If I'm wrong, Ill swallow a dollar bill sideways on film for it." It was meant for emphasis and dramatic flare. Sometimes it pays not to PWUI.

I was seriously just curios to know what your standards were. You make some valid points about just saving up for another gun.

Maybe I'm just lucky, but sometimes, luck is enough. :)
