your defense loads.... I did a lot of experimenting this one heres what I know, I like 124gr+p gold dots or 147 standard pressure fed hst. the 147 gave great expansion and between 13 and 14 inches penetration. in the 124+p I felt the gold dot did the better and was very consistent. I think any of these loads would be great in the 3.5in barrel and the 147 in the shield just because they were a little softer shooting. good luck with your choice.
