+1If reliability is your greatest concern, you really can't beat a revolver. I'd vote for a 4" barrel .38 Spl if it's strictly home defense.
Not always necessarily so as newbies can have problems no matter what handgun they are handling. So being new yourself you won't know what to look for in someone else handling a handgun.Riad, spend some time at the range and you'll quickly see what works or not.

Riad, I have the same problem with my wife, she hates shooting the 12 gauge. Go with the .38 with the 4 inch barrel, regular weight steel revolver (no lightweight alloy). Don't freak out your wife with high pressure .38 P+ ammo. Regular pressure .38 hollowpoint rounds, in a heavy 4" revolver, will have mild recoil, and kill a bad guy pretty well. Buy Double action S&W, Ruger, Colt (used), or Taurus (Taurus last, the semiauto are good but some of the revolvers have timing issues)
