To be honest, I just don't see how one would figure a ~4.5" bbl would be a better seller than a 5.6" barrel... do many people actually put cans on their 10mms? I know that some certainly do, but I would guess that there would be a bigger market for those wanting to hunt/achieve significantly greater velocity from their G29s. With a 5.6" G29 barrel, my stock-length SL barrel, and my AA .22lr upper, my G29sf would become a near-do-all backpacking/hunter/plinker sidearm. Wanna kill these ads? We can help!
