Little late on this Redhawk, bought one a couple of weeks ago. It is a sweet shooting gun, have run over 200 rounds without a single problem.
To me the recoil you would expect from that size of gun is just not there IMO. I guess overall it just seemed like the action was smoother than my Glock. The Glock guys will be all over me on that remark
It fact I just sold my Glock 26, the Beretta will take its place as my carry.
Also they do make extended mags for it. But right now they are back ordered like everything else. You can buy them directly from Beretta's web site.
