Having a heck of a time deciding whether to get a Night Guard 327 8 shot or a 627 4 inch 8 shot. It would be for general use including vehicle gun. I have been over the plus and minus ideas for quite a while and have not gotten off the dime. Just thought tonight I would just get both and be done with it. Then the thinking part kicked in again. Is there something that stands out in one over the other? Hate to seem confused but for some reason I just cant pull the trigger so far. Input would be appreciated.
