I recently bought a gen 4 g23 even though what I really wanted was a g19.  It was the fde color which I thought was neat and I am bad with impulse buys so I jumped on it.  I immediately ordered a conversion barrel for it but they were backordered.  As I read more about the gen 4 and looked through the Lone Wolf website they recommended that you replace the recoil spring and a couple other parts in conjunction with the barrel to make it function properly in a gen 4 model.  This didn't make me feel warm and fuzzy inside, especially since the gen 4 recoil spring was one of the improvements over the gen 3 pistols.  Not to mention the fact that we were now approaching the $200+ mark for the conversion barrel and other components.  

 

I sort of forgot about it bc it was on backorder, and bc I seem to have gun add and another permit to burn I began looking at the Sig guns.  I decided to buy a p226 in .22lr and buy the xchange kits they offer to shoot both 40 or 9, depending on which kit you buy.  It comes with a complete slide assembly.  Just take off the .22 slide and swap it for another caliber. 

 

...which brings me to the point of this post.  I looked into it for Glock and you can swap the complete slide assembly of a gen 4 (or gen 3)  from a 19 to a 23 or vice versa.  You just need to make sure you have the same generation slide as you do frame.  I looked online and found a brand new complete gen 4 g19 slide assembly for just over $300 that now allows me to shoot both 9 and 40 with complete factory reliability.  Also, there is no permit needed for the additional caliber bc it is the frame that is registered.  

 

This might be old news to most of you but I was pretty stoked about it and am happy to now be able to shoot both calibers with only 1 permit burned.  I also think this is good for a SHTF scenario where ammo might be available in one caliber but not another.

That is a sweet setup you have there Blake!!!

 

Love the 22 kits, but boy are those Sig ones finicky. Hopefully you got one of the good batches. CCI Mini Mags and Fed Game Shock shoot well in it, but of course as a premium.

Gen 4 19/23 slides are interchangeable. Swap the slide, barrel and spring as a unit and you're good to go.

 

Be advised the ejector of one caliber *may* work with the other. But if you want to be a purist (read 'certain of function') buy an appropriate caliber 'trigger mechanism housing with ejector' (#23 on the Glock pistol diagram) and install that in the frame when you swap the slide. Then for all practical purposes you have completely converted the pistol to the other caliber.

Yea most .22 kits are a PITA.  Once I find a 9mm xchange kit I doubt I will use the .22 much.  For now .22 and .40 will have to make due.  

 

I usually run mini mags in my .22 pistols anyway bc it seems that is the only ammo the pistols all universally like.

I did read that the ejector was the only difference.  I am planning on putting a crapload of rounds through it and see if there are any issues.  If there are I will order the parts.

The ejectors are different. It takes about 30 seconds to swap out ejectors. Go to glockparts or glockmiester and order a 9mm gen 4 ejector for a couple bucks. The 9mm ejector has 30274 stamped on it, the .40 is 28926.

 

You can also get an Advantage Arms 22lr conversion kit for your Gen 4 19/23/32.

 

BTW were did you pick up the G19 G4 upper?

Thanks for the input, if it's that cheap I will just order the g19 ejector.  

 

I bought the complete slide assembly off gunbroker.  

Looking at the glockmeister site they have the gen 3 g19 assemblies in stock for $340.

Blake, I might have the ejector in my glock parts bin. I will look for it. I also have some other stuff for it if you need. I have 10 new glock 19 mags, longer G4 mag release.
