It produces a MV around 1450 ft/sec from a 5" barrel. Use a heavy recoil spring.

...only problem is you are shooting exactly what 9x23 factory Winchester ammo is running, not .38 Super ammo.
The boutique ammo manufactures run 124/5s in the 1350 area which is safe in any Super, supported or non... 115s can be run to the mid-1400s...
