The Glock 21 is the old standby. Lots of punch and a double-stack magazine of good old .45 rounds will do the trick. Triple E is a good place to get it. The Glock has very few moving parts and is very reliable. If your hand is smaller, they just came out w/a smaller grip version of this gun. Don’t forget the Sure-Fire weapon light for when those burglars come in the house at night. Just make sure it’s not some drunk guy from PB going to the wrong house or you could get in trouble. Can’t shoot someone for trespassing.
