The only rounds I've carried in 9MM have been 124 +P, 115 +P+ and 127 +P+.

The majority of that has been 124 +P in Speer GDHP.

I'm getting down to the last of my carry ammo and I'm wondering if just going standard pressure across the board is a good choice.

I may be changing out to Federal HST in either 124 or 147 grain standard pressure. The tests I've seen and the reading/research I've been doing has this round as a solid choice in either standard or +P pressure.
