This round seems to have very high remarks for SD use in 9x19.
I know they make standard and +P for each, I have seen results in tests showing larger expansion for the slower heavier 147. Also it shoots only about 50 fps different in two loadings, perhaps in a shorter barrel. I hear it jumps less and recoils less than the faster 124 loadings.
1) Do many of you 9 fans load up with 147's for SD?
2) Would barrel length affect which load you use?
