Mas, I had some extra money so I treated myself to SW M&P 340. I'll probably carry 38's in it, but like the option of the 357 as well. Is there any currently sold 38 ammunition that shoots to the same point of aim and is reasonably close to the Federal Nyclad's recoil. I have a very short supply of the Nyclad ammo and I don't want to shoot it up, but I would like to practice extensively with something similar. Also, If I decide to go with the GD 135+p for carry, would I be gaining that much in performance for the heavier recoil? Thanks, Don B.
