I have a G23 gen 4 that I want to convert to 9mm. From what I understand, I just need a conversion barrel, and some G19 magazines. Is there anything else I should take into consideration, and would the conversion be reliable enough for an EDC, or would I be better off just trading in the 23 towards a 19? Only reason I'm even considering this is because I'm starting to have some carpal tunnel issues, and I'm really starting to feel the .40 when I go to the range. TIA.

depending on the 9mm you shoot you'll also need a 9mm extractor because the one
for the 40 S&W sometimes doesn't extract 9's. Also depending on where the ejector
kicks the brass you might need a 9mm ejector. Still with these mods, it's reliable and
cheaper than buying a new gun.

I wouldn't call it good for EDC until I had 500 jam free rounds out of the conversion.

To each his own but, if I knew I didn't want to shoot 40 cal any longer and had to replace all those parts and magazines, I'd sell my old pistol and buy new pistol where I know everything will work. Besides, it won't cost that much more when you consider all the costs of parts and mags.

Look what i got in an email today. Lol

If you were only converting it for less expensive range practice ammo, then barrel and some mags and you should be golden. With the carpal tunnel and knowing you plan to move on from .40, I'd make the move to an actual 9mm pistol. If the conversion didn't pan out, you'd be doing this anyway, you might as well skip all the work and expense in the middle and cut straight to the chase. A 19 or 45 would fill the bill nicely and you wouldn't have to hunt new holsters. Good luck.

I have several 40 to 9 barrels. One for each of my 22, 23 and 27. I like the idea of having two guns in one. Nice for travel and you have two choices when ammo gets hard to find. They have all worked very well. If they didnt i would not keep them.

For range use, magazine(s) and barrel.

For carry, above - plus extractor, ejector and firing pin ( .40 FP is slightly longer) plus reliably testing ; or better - just get a 19.

If you actually need it for SD I doubt you will notice the difference in a .40 S&W and a 9mm.

I have a Lone Wolf Arms 9mm conversion barrel for my Gen 3 Glock 27 along with 9mm mags and as far as I know, that's basically all you need.

I have a Gen 3 model 23 that I have used a Wolf conversion barrel in w/9mm mags. Never had the first problem with any ammo I have run through it. Since I have 5 other 40 calibers, I am probably going to convert it to a full time 9mm. I will do the complete swap, ejector, extractor and barrel. I hadn't heard of the firing pin difference, probably not going to swap that out.

Like gunsmoke92 said..... 9/45, etc.

 

[SDGlock23]

In the past I've used 9mm conversion barrels and mag only with good success, at some point I also tried using a 9mm extractor. To me, if you're having a hard time with the .40, you might be better off trading it in. Yeah you'll take a hit but it's just money, the money you would have spent on 9mm conversion stuff could just go towards a dedicated 9mm, like a G19 if that's what you want. Personally I think the conversion stuff is fine for the range but I wouldn't trust it as much as a dedicated 9mm for EDC work, etc.

Another option might be trying to go for a Gen5 .40, the slides are wider/heavier and they do recoil less, to me they feel about like a 9mm in terms of recoil. You'd probably want to try one out, but they definitely shoot softer, downside is that holster compatibility isn't there because of the wider slide and it's going to weigh a little more.

For my Gen 3 G-23, all I did was replace the barrel with a Lone Wolf and Glock 19 mags. Use this as my back-up to my Gen 3 Model 19 for training courses and competition, but if I were to carry it as a primary SD gun, would probably change the extractor. That said, have never had a problem with it just as configured. Also have done the same with my PD Trade-in Glock 22 and use it for students and never had a problem with just the conversion barrel and G-17 mags. Like having the option of taking them back to .40 if I want for carry. YMMV

I'm a big fan of the conversion barrel, every Glock I've owned in 40 or 357 has had a companion barrel in 9 mm and 9 mm mags so if it was just a case of wanting to shoot 9 mm, I'd go with the barrel and mags in 9 mm.

that being said....

with your issue with recoil that is causing you to consider switching caliber, would a different grip be beneficial to your condition?

before investing in a barrel and mags for your 23, I would suggest that you go to a range and rent a single stack Glock to try out.

the indoor range that I frequent has a rental program that allows you to try out any of the firearms they have for rent. for a single fee, you can try out as many as you want, just one at a time, you'll will need to buy ammo from them but where I go they have a house brand that isn't going to break the bank.

the reason I suggest this is that when I changed from a Gen 4-23 to 43X MOS, tho the dimensional differences are small, the difference in feel was very noticeable. I would suggest trying a 48 as the 43X is a bit snappy with defense ammo but you could try both (and any other brand handgun they have available) for a single fee.

Just get a Glock 19 slide complete from HGW.

I did the same for the same reason. I had fired about 200 rounds of .40 cal and 2 days later had terrible pain in my Rt. wrist. I had already bought a 9mm conversion barrel a few years ago from Storm Lake and it worked very well. I didn't change the extractor and I had no problems. I had planned to carry the G23 with the .40 barrel and practice with the 9mm barrel. I started wearing a support glove that I picked up at Walmart. Isolates the thumb and wrist. Won't sell my 23 as it is from the 90s and I wouldn't get anything for it. I still have pain from the 9mm so I am going to .380, been looking at the new Beretta cheetah. You might consider having the carpal tunnel surgically fixed, simple surgery even done with a scope now.

 

[steveasvitt]

I converted my G35 to 9mm.
Swapped out all the .40 internals for 9mm internals.
Stock Glock parts are cheap so might as well do a full conversion.

I am nearly 80 years old and my carry caliber is 357 sig but I recognize one day It may have to carry my 19 or 17 on a regular basis.

 

[bbstein2]

Did same in my gen2 23. Conversion barrel and mags and good to go. If CC mine I carry in 40 but I’ve shot a lot of 9mm through it and would feel plenty confident carrying it.

 

[Matteo1371]

I would not trust a 40-9 conversion for carry. Better to just get a 9mm since it sounds like you would prefer it. If selling the 40 for a dedicated 9mm is not an option. I think I would opt for a complete 9mm slide. Then at most you’d want to swap ejectors.

The exact same here. The gun seems to function OK but I've not fired enough rounds through it to be confident. I assume yours functions without problem?
