Always nice to know that your ammo will cycle in your weapon
without any problems.
The type of ammo used is the big question.
Do you want a JHP bullet to expand and penetrate at 3" barrel speeds?
There is also a heavy mass for deep penetration with or with out expansion.

Lots of bullet study is needed and maybe some water jugs are
in the works, for a final decision on your 3" SD selection.

A 3" can work but it is one reason I moved up to a 3.5" 9mm pistol......
for the Speer GD ammo with a copper jacket .
My 3.5" with the Speer #23611 Short Barrel +P ammo gets 1124fps.
