So i am going this weekend to make a swap for a S&W model 19 .357 mag with the 4" barrel (both guns are my dads...so its not costing me anything). I have been doing some reading on different ammo for it, and have read in several places that with the 19, shooting todays current "full bore" .357 ammo will cause excessive wear and tear on the gun. I don't want that...so it's generally recommended to shoot the older type .357 ammo, newer but slower non +P, or any .38 spl. Here's my question...which would be better, newer non +P .357 (i'm not even counting older "ball" ammo) or the best .38? Any specific ammo recommendations? Also, i'm sure some of you have read this guy's stuff... http://www.chuckhawks.com/ammo_by_anonymous.htm How reputable is he...does he have any idea what he's talking about?
