I use it for my carry ammo because I like sub sonic speed compared to
the lighter ammo.I noticed no difference in recoil.I also use 115,124 grain
ammo.

I like cor-bon 115 gr. If it doesn't hit them hard enough just keep pulling the trigger!

What you want in defence is accuracy. Placement means more than anything. What size or weight of the bullet means nothing if you don't hit the target. Pick a good load and practice with it a lot. Good luck.

I know I harp on this, but ANY quality modern hollowpoint will work fine for defense. I like 124 grain bullets in 9mm, but I would hardly be dissatisfied carrying 115 or 147 grainers. People put way too much mental energy into minute differences between rounds.

Ignore the gun magazine articles about defense ammo. Buy Golden Saber or Gold Dot or SXT or, if you must have semi-gimmicky ammo, CorBon DPX. Get some good training from serious instructors and practice what you learn. It's the latter that really makes a difference, not some paltry 23 grains of bullet weight.

I agree with Baldy and Mike. The differences aren't that huge. Buy what you can shoot a lot of and shoot it. Proficiency is the hugest factor in the effectiveness of your ammunition/pistol combo.
Do you want a little more weight for a little less velocity or vice versa? It doesn't seem to matter that much.
