Outside Diameter of Glock 10mm & 45 acp Barrels?

[missionary5155]

Greetings
Are the outside diameters of the calibers 45 acp and 10mm Glock barrels the same ?
Looking to try out the 10mm using my Glock 21 frame and hopefully the same slide.
Thanks !! Mike in Peru

My Gen 3 20 and 21 barrels have the same OD.

Thank you Sir ! I thought I remembered reading that time ago but wanted some confirmation before I stepped off into the deep.
