I have a Ruger P-90. .45 calibre
:Actual Size!:
I decided on a .45 for the stopping power and its subsonic.
I am not worried about over 50ft, more like close in defense.
If some SOB enters the house, the better hope I get the .45.
If Barbara gets it, the don't have a chance in hell.
She is a great shot, even with my gun.
(she also has a .38 special)
