Glock Conversion From .40 to 9mm

[rwb1500]

Ok, I've been discussing it in a bunch of other threads, I figured I'd start a new one to get some clear answers. I have a Glock 27. I'd like to convert it to 9mm at some point. Do I need an aftermarket barrel? Or could I use a factory Glock 26 barrel? Also, should I replace the extractor and ejector?

Any body have any experience with this?

Glock website shows that the barrels from both the G26 and G27 have the same height and width measurements.

Here is a link to The firedragon conversion:

Your .40cal (23/22) will require a conversion barrel because the OD of the barrel is larger than the 9mm counterparts.

I highly recommend changing the ejector block. It's a <$10 part. It will eject more reliably in my personal experiences converting several 23's and 22's to 9mm.

That's what I figured, they would not make the .40 barrel thinner walled as it is a higher pressure round.

That's what we figured. Makes sense. And for $10 I don't see why not.

Can I ask why you would want to do this? If you were talking about a .22 conversion, I might be able to understand it from a training perspective, but a .40 to a 9mm doesn't seem to make any sense. I'm sure you have a good reason. Could you explain?

Because its almost half the price to shoot and it's cheaper than buying another gun.

That about sums it up.

BUT, when you buy a 9 to 40 conversion kit, that is exactly what you get. A THIN outside diameter 40 barrel. Companies sell a ton of them. Just not for me.
