Defense Hollow Points- 115gr Hornady Critical Defence or 115 gr Speer Gold dots
Reason low recoil for the increased recoil of a compact handgun. Even though the Ruger can be fed anything, you're gonna want a lighter load in a compact so you are more on target for any necessary follow up shots. Though I have put lots of Remington Home Defense 124gr hollow points through mine with no problems. I keep Gold Dots in mine, and Critical Defense in my 2nd mag.
Range ammo Federal 115gr Full Metal Jackets.
Reason cheap, and plentiful. And it lets you practice with the same grain weight you will be shooting.
Get yourself a good Half Moon Kholster for concealment and you are set
