Information from the book Living With Glocks. Velocity is from a Glock 36. It has the same length barrel as the Glock 30. UMC Hardball at 810, Cor Bon 230 JHP +P 900, Black Hills 185 JHP 931, Black Hills 230 JHP +p 930, Winchester 230 SXT Ranger 864, Winchester 230 SXT Personal Protection 833, Eldorado Starfire 230 805. Some of the same loads out of a 5 inch 1911. UMC Hardball 850, Cor Bon 230 JHP +P 953, Black Hills 185 975. The other loads I listed were only tested in a Glock 36. Hope this helps. A 230 grain JHP that still runs at 900 fps or more is a pretty impressive load out of a 3.8 inch barrel. I have both the Double Tap and Buffalo Bore 230 grain loads that I carry in my Glock 36 and they hit hard.
