So I'm thinking about adding a laser on to my Keltec Sub2000 gen 2. Never owned one before and don't know much about them My questions are what's a really good laser for in or around fifty bucks? What color is best red or green? I want one that is rechargeable and I want it to be a compact, slender package. I Want to attach it to a rail or M-lock slot. Probably not going to be for really long range shooting. Any suggestions would be much appreciated.
