I have started "downsizing" the calibers from .45 and .357 and .40 to 9mm, 9x18 and 380. Which leads me to my Glock 23 Gen 3 Do you think it wiser to see my 23 and buy a 19 or replace the parts needed to convert the 23 to a 19? Sometimes I don't trust changes like this but I haven't heard any negative comments.

I like my 23 just the way it is. I wouldn't convert to another caliber. If I am not mistaken, conversion barrels are drilled out of round so the firing pin can strike the primer. If you need a 19, my advise is to buy a 19.
The Glock 19 and Glock 23 are identical frames with a few exceptions:
You can't convert a Glock 23 to a 19 simply by putting a 19 barrel into the 23, primarily because the ejector in the 23 is straight and the ejector in the 19 is bent because of the smaller 9mm cartridge.
What you could do is buy a lone-wolf 40-9 conversion barrel. That barrel has the chamber slightly offset to compensate for this ejector difference. You also need the 9mm magazine.
IMHO, it may depend on the purpose of the gun. If it's strictly a range gun, I'd go conversion, which has the (potential) benefit of helping out in the event of another ammo shortage. For carry, I'd prefer to keep things stock, for a variety of reasons.
Thanks for the advice. I think I will go that way.

One point in case you were unaware: if you are using a 40/9 conversion barrel, leave the 40 ejector in place. If you are using a glock 9mm slide and barrel, use the 9mm ejector.

I got a 23 for the purpose of having a multi caliber gun when ammo is hard to find.
9mm and 357 Sig conversion plus an Advantage Arms 22lr conversion
I never had a problem running 9mm ammo through my 23 with the original ejector in place. I would try it first with the 40 ejector and if it works leave it be. If not the change from 40 to 9 is a 2 minute job.

Get the barrel, it's cheaper than a new gun and you'll have the best of both worlds. Also, even though your mags say .40, you can shoot 9MM from them. If you have a concern, use them for the range and get a couple of G19 mags.

Trade the 23 out for a 19.

I have lone wolf 357 sig and 9mm barrels for my G22 and they work great. I have the 9mm extractor but have not used it because it is reliable without it and the brass drops right at my feet. If it was my EDC gun I'd put the extractor in.
The market is flooded with G22/23 police trade ins so I doubt you will get a fair amount for yours. Get a barrel and a couple mags.

I bought a KKM conversion barrel for my 23. Never had a hiccup with the .40 extractor. You will want some 9mm magazines.

I am one who still likes the 40 S&W and don't see myself getting rid of my G23 or G27.

I never had any issues using my G23 magazines with a Lone Wolf conversion barrel. For about $120 I was well pleased with the 'converted' Glock 19, and could be back to .40 S&W with the original barrel in seconds. As Saddlebag Preacher notes, you can always get a couple of Glock 19 magazines if you will be looking for more dependability away from the shooting range.

They are not that expensive. Just buy the G19. If you find that you stop shooting the G23, sell it.

23 is my fav pistol.
I have no plans to get the 19. I'm a big guy, 9mm isn't really any easier for me to shoot.

After using a G-23 as a CC gun for the past year I'm confident in the .40S&W.
Even though I'm tight with my money the difference in cost between the .40 and 9mm is acceptable to me because I want a heavier bullet.
Bottom line; I got no use for the 9mm.

Yes, you are mistaken. The primer in both calibers is in the exact same spot in relation to the firing pin. There is no offsetting.
The only time he bore would be offset is when switching between a rimfire and a centerfire. Otherwise, there is no change.
The cutout in the side's breech face is larger in the .40 to accommodate the larger diameter of the case head. The barrel hood is cut to match. The hood on a 9mm conversion barrel is sized to match the wider cutout on the .40 slide. That is the only difference in geometry between a factory barrel and a conversion barrel.
I have conversion barrels for a number of .40 Glocks, and all have worked fine with no changing of ejectors or extractors. However, I have not had 100% reliability running 9mm through .40 mags, so I always match those with the caliber.
And I'll echo what others have said about .40 availability during the last couple of ammo scares. That caliber seemed to be readily available when 9mm was not.
Buy the conversion barrel and try it out. Worst case, if you don't like it. You can always decide to sell the gun and barrel at that point.
