[front sight]

I have a full size Colt 9 mm. I want to try shooting 9x23. What do I need to convert my regular 9mm to 9x23. Freeboring of barrel? up to what lenght? Also what magazine should I use? Any previous (how to) posts regarding this topic? Thanks!

Call Bar-Sto and get a barrel and use 38 super mags. Also trim the ejector down to the difference between the 9mm and 9x23(2mm).
Make sure the extractor fits the 9x23 rim and install a recoil spring to match the loads that your going to shoot.

Now you have a two caliber gun.

Does the 9x23 use the same extractor as a 38 Super or a 9mm?

Or does the extractor have to change as well as the barrel (of course)?

Same extractor, same ejector...both just need to be tweaked to work with the cartridge.

Also thing to possibly look at is to have an O/S firing pin stop fitted to keep the extractor from rotating, and have a firing pin fitted so that the primer isn't able to bleed back.

Make the the recoil spring matches you load.

Now you have a good place to start.
