A whole bunch of glockaholics around here. A glock 23 is going to run you about 500 bucks before taxes/fees. That's more than you want to pay for something that is going to sit in a drawer in your nightstand until you take it out to the range and shooting while camping (I get the impression you won't be doing much shooting, otherwise you'd already have a bunch of guns.

Just a opinion...mine of course...but if you buy a handgun or any weapon if you are just going to toss it in a drawer and not use it unless an intruder comes in...well don't do it. Training in use of a handgun is VERY important. Shoot when and all you can and take a firearm safety class. We shoot about once a week and it is a fun sport, but you have to be prepared.
