the grip on the SF G30 is 3mm's smaller, front to back.

(SF is on the left)

i tried 'em both at the gun show today and really couldn't feel much difference.

i have VERY small hands, and decided to get the G29 non-SF recently. i shoot it better than my G19. the SF models just have an odd feel to me. it's all personal preference though, many folks prefer the SF frames. i had a G21 SF that i sold, just couldn't shoot it that well due to the odd grip....
