I want to convert my 23 to take 9mm, any input on barrels ad where to get them? Thanks

Not sure if what you're trying to do will work. www.glockmiester.com has a page that will tell you what different barrels will work on what Glocks.
Good prices!

You'll need an aftermarket 9mm barrel made thicker specifically for use in a Glock 23/32.  The factory G19 barrel won't work reliably because it is thinner.  For conversion to use protecting your hide, you'll want to replace the .40 cal extractor with a 9mm sized one, and use factory 9mm mags.  For range use, most people find the .40 extractor works 99% of the time, but don't trust your life with 99% reliability.

www.glockmeister.com, www.topglock.com, and some others sell these conversion barrels and parts.
