I recently purchased a Walther P22, and a Marlin 794 at Gander Mountain for the express purpose of teaching the wife how to shoot.
I haven't had the chance to shoot the Marlin yet, but all in due time.
That's a pretty basic combo, and the only thing I have that shoots the same ammo.
I do want to get a Beratta CX4 Storm to compliment my PX4 9mm handgun, those not only take the same ammo, but use the same magazines, can't beat that.
For further home protection I have a nice Superior Arms AR15 in .223.
And the piece-de-resistance.... a wonderful Mossberg 500 jic (just in case).
For me, that is the best of all possible worlds, and I think I have about all the bases covered....... for now
I know I could have gotten better prices than what I picked all of them up for, but they were all there, and all new in box, so I figured what the hell... save a few bucks, or take them home now.... I chose to get the P22, Marlin, and Mossberg all at the same time and place.
Now just to figure out how to pay for them all, and find the time to take the wife out shooting.... oh, btw, learning how to shoot was all her idea, and she loves the P22.
