I have shot both lengths, and the 32" seems to swing a bit smoother, but the 30" seems to do the job also. I didn't think that the 32" was too long. I guess if you had the 30", you could add the Beretta weight accessory on the end of the mag tube and experiment with the differant weights. Have you had the chance to shoot a 30" or a 32" model? I would give that a try first, maybe that would help with your decision.
Had both. The 32 was just to long for me and I like long barrels. Eventually everything gets sold, a 32" is not the easiest sell. Many say the 32" is best. That may be. But why does it take a long time to sell a 32", few are seen and most 30" seem to sell in a heartbeat.
