How about a 1911, in 9mm.
Since it is a house pistol no reason not to get a full sized pistol.
40K rounds on a Springfield loaded 1911 in 9mm
A full size 1911 in 9mm is a joy to shoot.
I happen to like 1911s others will say old tech, finicky, etc.
The problems I have had
failure to chamber one round, bad brass on a reloaded round before I case gauged no fault of gun
Some failures to lock back, bad mag springs, replaced mags, problem solved.
So 40k rounds and no failures I can blame on the gun.
One of my friend's wife who had never shot a pistol before the current range session was shooting his Glock .40.
She was having a hard time with the Glock (nothing against Glocks or .40,just maybe not the best choice for a new shooter)
I let her shoot my Springfield and she loved it and was making good hits, than asked hubby to get her one. (Hubby not happy Springfield is a 1K gun as opposed to a $400 one)
Not saying a 1911 is the right answer, but should be worth considering.
