hello...I am still confused even with all the searches I have made. Can someone please tell me for sure if my alloy 642 can use +p ammo? On the barrel (all 1 3/4" of it), says: 38 s&w spl. Thats all.spec ord is 8026 which I believe to be Oct 26 1998. Any thoughts? oh, trademark and airweight are on the right side not the left. barrel stamps on left. Thanks.
