Question about multiple calibers in G19
Been wanting the ability to shoot 9mm, .357, and 40 out of the same gun. I was recently talking to a gun store employee about it and he insisted it was impossible. I know it's not.
My first question is this. Can it be done with a Gen4 19? What about a 32? Seems like everyone uses 23s. What's the differences between them? Also, it's my understanding that all one needs is the barrels, recoil springs, and mags. Is this true? |

I'm not absolutely sure about the Gen4's, but in the G27,23,22 & 35 Gen3's you can run 9mm and 357sig without changing anything except the barrel, and the mag for 9mm if your worried about true reliablity (use mags from G26,19,17, etc).
In short, all of the 40S&W Glocks can be converted to 9mm, 357sig and a few other less popular rounds. None of Glocks 9mm's can be converted to anything else, except 22lr (that I'm aware of) |

I fogot about this question...
Quote:
The aftermarket 9mm barrels have the same outside diameter as the OEM .40 barrels, so they fit properly/tightly. You can not run a OEM Glock-brand 9mm barrel in a .40 Glock, its too loose/sloppy at the muzzle. |

Just to complete the picture, the limitation is the diameter of the original chambering's case head. A .40 case head will not fit in the 9mm width slot in the the G19's slide.
Really, a 9mm shouldn't work in a .40 slide because the extractor barely has anything to grab, but in practice it works okay because it is only .5mm difference. You could buy a complete second top end - slide and barrel - but that's a waste. A better question you might want to ask is if there is really any reason to want to shoot .40 out of a G19. What's so wrong with 9mm that it isn't good enough for your needs? |

Just remember you can convert down and not up, well except for .357 Sig and .40's, you can put a .40 barrel in a 357 Sig and visa versa, but you cannot convert a 9mm Glock up to 357 Sig or .40 S&W unless you buy a complete upper.
With the .40/357 Sig you can buy a 9mm conversion barrel, but it has to be a conversion barrel, not a regular 9mm barrel. |

I've got a 23 -- which is .40 S&W. I have 9mm and .357 Sig conversion barrels. They all work properly, using the same mag. (The barrel makers adjust the barrels sligthly so that the extractors work and headspace is correct.) For most of these guns, the mags work, too. (I had a SIG 2022 with a 9mm conversion barrel that shot beautifully, but wouldn't lock back the slide with the last shot, whether I used .40 or 9mm mags.)
Sell or trade your 19 and get a 23 -- and you can do what you want. Generally speaking, you can get conversion barrels for some guns that let a smaller caliber be used (as with a 9mm barrel fit that works in a .40 or .357 SIG slide), but few 9mm guns can be converted upward, because the slides won't accept the larger-diameter barrels. (Some of the older Witness pistols are an exception, as the 9mm and .40 barrels had the same diameter.) There are a number of YOUTUBE videos showing Glock 40s using 9mm FACTORY barrels. There is "slop" but they seem to work properly with generally good accuracy. I wouldn't do it, but it apparently can be done. |

Thanks guys, should have been more clear. I knew that the 23 and 32 were 40 and 357 respectively. What I couldn't understand is why they could be converted and a 19 couldn't. It's the hole in the end of the slide. Pretty simple and makes perfect sense.
As far as shooting 40 over 9mm, I just like having options. I may end up getting me a Gen4 32 and 9mm, 40, and 22 conversions. Just seems like fun. Thanks again. |

It's not the hole in the end of the slide - it's the slot where the base of the cartridge case and the top of the barrel hood sit in the ejection port.

Converting G23 to .357 sig. Maybe not necessary, but I tend to stay on the low end of the load. .357 sig is hotter than .40 s&w. I don't want to bash the gun too much.
Converting G23 to 9mm. You may need stay on the high end of the load. The barrel wall is thicker and the spring for .40 s&w may be too stiff. A weak 9mm round may short cycle. I like my G23. Got it from my coworker for cheap. He couldn't wait to sell it to buy the new gen 4 sub-compact. Silly. -TL |

The 23 and 19 use the same spring.

So if you convert your Glock 23 to .357 SIG by changing the barrel there will be absolutely no difference in wear than if you had a Glock 32; it will have the same barrel, the same slide, the same recoil spring, the same frame, and virtually the same magazine as a Glock 32.

There was a question earlier about Gen 4... My Lone Wolf 40-9mm conversion barrel works fine in my G23 Gen4. It also works great in my G27 Gen3. (Sticks out of the slide slightly but works.)

If you want to see why, lay a G27 barrel next to a G23 barrel (or a G26 barrel next to a G19) and you'll see there are more differences than just the barrel length. The G27's barrel (or G26) needs to tip up at a steeper angle than the G23 (or G19), so if you look closely you'll see that the angle on the locking lug on the barrel that engages the locking block on the frame is different. And that means you're putting a lot more wear on the frame of your G27 when you shoot it with a G23 barrel.

Hunh... learn something new everyday.
Is the lug angle the same for the 23 & 22 & 35? |

.41 Action Express
http://en.wikipedia.org/wiki/.41_Action_Express
40 cal with the rim cut to 9mm Luger dimensions to cycle in 9mm actions. Might be able to find a barrel to run this in your G19. It's a good round. Just need to reload for it. All the Best, D. White

I don't know about the dimensions of the Lone Wolf barrels, but the Glock barrels are specifically designed for each gun and aren't designed for the other guns. And if the Lone Wolf barrels are designed to work fine in both that means they're ideal in neither. There are several reasons the Glock factory barrels are better and more reliable than any aftermarket barrels; I guess that's yet another reason.
