Alright, so I've decided to add a couple new handguns to my collection. I love the Sig P226 Tac Ops. Now, for my choice in cartridges.... I already have a nice collection of 9mm and 40s&w. There is no option for a 45acp. Besides, the only 45 I've grown accustomed to and love shooting is the 1911. I also wouldnt mind another 40. .. Love shooting it. However, I do have another option for this Sig. The other option is chambered in a 357sig. I always enjoyed shooting the 357mag round, but the 357sig is new and unchartered territory for me. Can anyone out there shed some light on this type of ammo and what its equivellant to shooting?... Or at least a close proximity.... The more I read, the more I am interested. I just dont want to get caught up with availabilty issues or a round that I won't enjoy shooting. If you're wondering why I'm not leaning toward the P226 in 9mm, its because I have something else in mind for that.... the Walther PPQ 1st Edition model. The First Edition only comes chambered in 9mm, so this will not be an uption for me with this Sig. If anyone out there is shooting the 357 sig round, please let me know what your thoughts are about this particular round.... both pros and cons, of course. I would appreciate any feedback on the subject.
