I was minutes away from buying a 10mm barrel for my G21, then I gave a quick look at the 45 Super...
It needs only $35-45 in parts - the same parts you'd need to add with a 10mm conversion - Recoil buffer, steel guide rod and a 24lb spring.
But you can use the original Glock 45 barrel.
The Super still delivers ~1200+fps and ~700ft.lbs.... its the same performance as the 10mm, but without the $130 barrel swap and the 45 Super ammo is noticably cheaper too.
