[445gsd]

I've got a 40 S2Kg2 Glock model and have decided that I would prefer to go 9mm. I got it for a great price and the prices for the G17 version seem though the roof.

Is it possible/feasible to do a caliber conversion? I would guess barrel assembly (I saw a post was only $68), a new bolt, possibly new recoil spring, and maybe ejector - which may be the big hurdle.

Thanks for any help!

New barrel and bolt face (Just the front half). Same recoil spring and rear half of the bolt (weight). Gen 1 barrel assemblies ran around $68. I don't know what the Gen 2 version costs. And it will require a phone call to order the parts. Kel-tec doesn't general list assemblies like this in their parts online.

The prices for either caliber is the same price around here. Sounds like your guy is gouging the price. You might call the factory. They may offer a Caliber swap for $40 or so. Last I heard they were not selling barrel assemblies. But it can be done.
I scored a bolt assembly and barrel assembly (9mm) from the trading post here. Only other thing I needed was a 9mm magazine.

Try your G22 mags as converting a G22 to a G17 configuration can happen with only a different barrel. The mags feed lips are close enough to hold onto the 9MM cases..

I don't think it will work the other way IE: G17 to G22 as the bolt face on the 9MM is smaller than the .40, however the extractor on the .40 will grab the 9MM rim as it is only <.050 smaller than the .40, but that gets cut in half
(.025) for the extractor as the barrel is centered on the bolt face.

Pretty sure the extractors themselves are identical.

I am currently looking for a used G23 for a carry gun, but am planning a 9 MM G19 barrel for it so I can shoot 9MM's if needed.

I'm sure these questions would be answered for sure at any Glock related site.

Here's a pic of a .40 mag with a 9mm in it. It holds on to it just fine. The cartridge stripper on the bolt compresses the top round in the mag away from the feed lips until it passes behind the cartridge then the mag spring pushes the round up and the stripper shoves it into the chamber as the bolt closes.
