Hello All, I recently came into some money and dont want to squander it.. So I decided to get some advice before buying shotgun accessories.. I have a Mossberg 500a. 18 1/2 inch barrel. Heat shield, pistol grip with 3 point tactical sling. But am looking into getting some add ons for it.. Is used for home defense only.. Looking for a flashlight/laser to mount on it. But yet local GS has one for 300 bucks. NOT !! I paid only $199 for the whole rifle 14 years ago. Any suggestions for a reliable light/laser that wont break the bank ? Also, I have read that the newer 500a's cannot accept an aftermarket pistol fore grip. Any clues to say if mine will accept one ? What to look for etc. ? Thanks for any help..
