My 40sw load pushs a 155gr GD at 1300fps from a 4" tp40 kahr. Far from slow and weak. Hard for even a 357 sig to out perform . Or for 45+p loads to put more energy on target. Yea I have that too
Dunecigar A 9-23 would also be a good choice down there if ammo is readily available. What can you get in that cartridge.
