I liked the 357Sig round.....very comparable recoil wise to the 40......ended up giving it up, with the necked down case, getting good case consistency with reloads was at times tedious..but critical to the round chambering correctly, and factory ammo was a bit more costly and not as easy to come by. I had a factory S&W M&P in 357Sig, they don't manufacture them anymore but it was reliable.....also added a 40 barrel for variety
