I have a personal preference for .40 S&W. A little more power than a 9mm and it’s naturally subsonic making great for use with a suppressor.
My question, what would it take to convert a 9mm Dagger to .40 cal? Is this even possible? The .40 magazines fit perfectly however it seems the ejector would be wrong. Obviously you’d need a new barrel and I think that might get tricky because the hole in the end of the slide would be too small of a diameter.
Maybe a better route would be to buy a stripped lower and build it out. Not sure if that would be cost effective vs a Glock 23 OEM.
Gonna need the link for that slide…if its already RMR cut you are getting a heck of a deal because to RMR cut a 23 would add $50-100 more depending on who did it (plus shipping there and back).
I bet to convert a 9Mm Dagger to a 40cal dagger you need the following:
a glock 23 40 cal Top End. Basically a complete slide, and a .40 cal barrel.
glock 23 magazines.
then to go back to the dagger. you could just swap your other upper end on it, and put in the 9mm mags. HOWEVER… if i’m right with the Glock 23 top end, all you’d need to buy really is a 9mm barrel with the outside diamater of a 40cal like the ones sold by lone wolf and so many other companies… then all you’d ahve to swap out to shoot 9 again is the barrel and mags.
of course with the glock 23 top end, you also open up yourself to being able to shoot .357 sig. all you need then is a glock 357 sig barrel, and you can technically use the 40 cal mags to shoot the 357,but if youre a purist you can of course buy 357 magazines if you wished. I know guys who buy the glock 23 and 32 respectively to do just this, have one gun, which can shoot 3 calibers… its kinda the ultimate prepper pistol as its versitile that way.
All you need is a Complete gen3 Glock 23 slide and to change the ejector from 9mm to a .40 S&W or .357 Sig extractor. DONE! Works on all Glock19 Gen 3 aftermarket frames as well. However, avoid gen 1 and 2 frames as they may not have been reiforced to handle the larger caliber such as .40 S&W or the .357 Sig.
Wouid the barrels work? I know the Gen3 Glock 9mm’s used different barrel lugs for the different lengths. If the .40 cal shares the same Gen3 19 lug that the Dagger uses(And Gen 5 double stack Glocks) then the rest of the internals should swap over fine.
welcome to the forum @john5 !!! glad to have you! I assume you’re including the barrel with the complete 23 slide. I dont know anyone as of yet to have tried this on their dagger Frame. yes theoretically it should work. Personally i’d love to see them produce a g23 equivalent setup from the factory so that we know it woudnt have any serious issues and would be warrantied.
A glock gen 3 19, and a gen 3 23, can swap barrels with no issues.. you can also do the 32, which iirc should be the 357 sig. which also will fit in either. The thing about the 19 is, the barrel is the barrel has a smaller diameter than the 40/357 sig.. so you need to use the 23’s slide with a larger diameter barrel, cause the sig and the 40 have a larger diametere to permit the larger projectile. Lone wolf was a big one that folks used to buy the 19 glock 9mm replacemetn barrel so that when you bought your glock 23 or 32, you could then convert to 9mm. the 40 and the 357 also would work with the same mags,
basically what im saying is you wouldnt buy the 19, cause the slide would have too small a diameter end for the barrel to fit through… you’d buy the 23 or the glock 32, so that it would shoot both 40 cal and 357 sig, as they also use the same magazine between them so theres little to worry about swapping there.. and then you’d buy an afermrket glock 19 barrel, but one for the glock 23/32 slide. and use the 19mags, and you’re golden..
i feel like i got too confused there.. but thats the basics.. has nothing to do with the lugs length..
I have to walk back my earler statments. The Dagger frame being a two pin rather than a three pin like Gen3 Glocks might be a factor. Gen 2 Glock 23’s initially came out with 2 pin versions over time thay had issues with the frames cracking so they becan to reinforced frames. Later in Gen3 Glocks specifically added another pin for the support of higher calibers like the .40 S&W and .357 sign vaiants of the G19, G23 and G32 frames the added an additional locking block pin for additional support. I’ve ordered 1 Dagger compact and 2 full size and will examine them once they arrive to confirm the frames have been reinforced at teh necessary points per Glock. If they have they have they should be 100% compatible. If not reiforced to Glock statdards there could be a potential issue in reagrds to wear and tear. However, there several Gen2 two pin g23 models that have functioned without issue. Just a matter of severity of use and type of ammo used. I’m supprised that dagger elected not to use three pins for the locking block like P80 and many others. I guess drilling that extra hole is expensive.
OK! I have put my first statements to the test. Yes, you’ll need a Glock 23 upper and barrel. a 9mm barrel is not compatible. Next is the ejecter on the trigger housing of the frame. I have built a Dagger 23, tested and it works amazing. Also, I believe PSA and reiforced their frames compared to gen 1 and 2 Glocks. Mine has runs flawlessly no issues what so ever. Here is my build info.
Glock 23 Slide
Zaffirri glock 23 Barrel
Dagger S Frame
Serpico Trigger with polished trigger bar.
Glock 23\32 trigger housing with ejector.
These were all the parts I need to complete my build.
is what i was saying. that barrel has the outside diameter that fits the hole on the 23 slide properly. while keeping the bore the right size for the 9mm.
Built it specifically as a dedicated G23 Build. Got plenty of g19 uppers I can swap if I want but then I’d have the switch the trigger housing as well or at least the ejector.
im curious as to why you’d have to swap the trigger housing / ejector if you put a 9mm (g19 slide Setup) on your frame you’re using for g23 build… i’ve never had to do this with standard glocks, and that doesent just include switching down to a g19 size, but also includes not having to change anything but the magazine to fire 357 sigs out of my g23 build. that said, i would expect the same to be true for the compact dagger line to be able to do the same thing.
