You might also consider a Taurus Judge, shoots 45 long & 4/10 Shotgun shells, will stop most people and won't go through your neighbors wall. Like the Glock, not terribly
expensive and a reliable utility weapon.

Now, if you like shooting a piece of art, I love this beast

and like our cars, lots of cool accessories to be had.

Or if you choose utility, a Glock 23.

What ever you get, make sure to get some training and spend time shooting (wife too) as like driving fast on the track, seat/grip time is the best investment to make you safer & better.
I love this beast.. But that will set you back (if you include the billet speedload set up) close to 4 regular Glocks.
