A litle pricy but worth it.
This is an outstanding product works perfectly for my 40 cal glocks
EGW Chamber Checker
If you are serious about make the best cartridge during reloading, the EGW Ammo Chamber Checker is a necessity! I've reloaded over 4000 rounds of various calibers, and every round goes through the chamber checker. I have used a micrometer because they did not pass the chamber check, and they were close to spec, but not close enough. Save yourself a lot of difficulties, and spend just a little more time preparing your rounds.
