I used to carry for a few years a 6" .357 mag revolver as a duty gun fed with 125 grn hollowpoints. I saw how this load worked on the street and it made a lasting impression.
Which is why the .357 sig was developed but it wasn't very long before it was downloaded from the 1450fps that it originally had.
We also have to acknowledge the changes in handgun ammo brought about by the FBI protocols. Which in my view has made all handgun ammo perform better and has made it all more or less perform within 15% of it other no matter what caliber. I know I have just answered my own questions I am going to post. But this .357 sig is an itch that keeps coming back.
Then today I was bored on a long conference call so I had the volume off and watched some you tube videos.
Underwood ammo is interesting especially looking at 9mm and .357 sig.
9MM 124 grain gold dot +P+ .357 sig 125 grain gold dot
FPS 1300 1511
FT LB 464 634
Expansion .703 cal .57 cal
Penetration 13.25" 15"
So the question is are the difference listed above really going to make a difference?
What do you think and why?
