I'm sure they will sell well. For my part I fail to see how .7" extra barrel length will offer any significant advantage. Sounds like advertising hype to me. I find nothing wrong with the 3.3" in the recoil or accuracy departments. Were it my choice I would have rather seen the 3.3 with a 6 round magazine. A little more frame length and another round would have been a better choice from my standpoint.
