35-45%, but in a home defense situation at night, it’ll blind you temporarily. Only for outdoor, daylight use. I shot a ported G32/.357sig before I bought mine after 9-11-01, and after turning-off the indoor range lights, I couldn’t see for 15-20secs. Also makes it MUCH louder inside in break-in defense. And you don’t want to fire from hip; you’ll get flash-burned badly. 3 point weaver stance, only, arm extended.
Rent and shoot one first, before you get yours done.
Yeah, the flash is my biggest worry. Except I don’t know where I can find one to try around here. I want to get my G30 ported and use the 10mm conversion barrel which might make it tolerable to shoot.
