i have a question on the glock 23 to turn to 357sig is it true all u have to do is change out the barrel and load the 357 into the 40cal mag? i thought u had to change the entire slide out to 357sig upper! and i was told with the 23 you can also shoot 9mm the same way by switching out the barrels is any of this true?
No matter what anyone says you can never own enough guns!!!

Just the barrel for .357, unless it's a Gen2 23, then it's a no-go.
9mm may require a different follower, extractor, and/or ejector - but they're all inexpensive parts.

Yep, Lone Wolf Distributors - Main Page. Get a 9mm barrel and you will have to have 9mm mags. Ive been told the 9mm will work fine with just the barrel, but the spent caseings may hit you between the eyes. Then you may want to change extractor and other parts.

If you want to stick with a Glock barrel then G23/G32 barrels are 100% cross compatible. No "conversion barrel" is really needed. For 9mm a special 9mm conversion barrel (non-Glock) barrel is required. The standard Glock 9mm barrel had a smaller OD than a 40/357. The conversion barrel for 357/40 -> 9mm uses a thicker walled barrel with the same OD as the 357 and 40 barrel.

U can shoot with 40 mag but if your carring 357 i would use the 357 mags

With 9mm barrel and mags, it should work just fine. Some have a problem, but replacing the ejector. etc. probably isn't necessary. As for the casings hitting you between the eyes, "Duck and cover."
.357 Sig rounds will feed thru a .40 mag just fine, but not the 9mms. The .40 slide is the same dimensions as a .357 Sig. Barrel change needed only.

Dont know for the .357sig but I do know that with my Glock 23 I just got the barrel(from Lone wolf a stainless ported one) and a Glock 17 magazine and that was it it ran 100% reliably..didn't need to touch any of the other stuff listed just the barrel and mag.
The .357 Sig is a .40 S&W cartridge necked down to .357 so no problem with the Glock 23 magazine. Just a Glock.357 barrel and your good to go. That said if you put the .357 barrel in the .40 slide and then have a problem would that void the warranty ?

The .357 SIG case isn't exactly a .40 case (it's based on the .40 but the dimensions are slightly different), it's close enough that either one feeds in either caliber mags, etc. .40 S&W cases necked down to .357 SIG will be a bit shorter in length and may not hold the bullet as well.. A couple of old machinists I shoot with do it and have no problems, but I don't know if they're shooting hot loads.

No problem with just changing to .357 Sig barrel. I go back and forth between 40 and .357 Sig. 40 cal magazine works fine. The only change that I made was installing a Tungsten guide rod. Added weight up front helps on the snappy recoil!

To safely do the .40 >> .357 conversion, you must start with a 3-pin (vs. 2-pin) frame. The early G23's, etc. had 2-pin frames, and should not be used.
(2nd Generation was mentioned.....not ALL 2nd Gen G23's are 2-pin, though!)
The early G23/32 magazines were identical, even marked ".40/.357" on the back. Several years later, GlockInc. tweaked the follower a bit on the .357 version, but in my experience, they are still totally interchangeable.
