i think a house gun should have both night sights and a weapon mounted light/laser combo. All my Glocks 19,23,21 and hopefully 26 after christmas wear truglo tfo sights. they glow great in the dark but i like them best in the daytime. they jump out and catch your eyes in day better than any other sight ive seen.
i think the house gun should also have a laser/light combo for target identification. im not shooting anything i cant identify. one of the rules of gun safety. the laser doesnt add any weight and in the dark the red dot can be put on target from any position. i picked up a streamlight tlr-4 from midway usa for 109.00 on sale through december. if money is an issue i would go with the light/laser combo first.
