I responded to some spam and for the amazing low price of "FREE!" *(plus 14.95 shipping and handling) I ordered a Tacticon laser sight. Since laser sights of various kinds retail for scores or hundreds of dollars, and the rule "you get what you pay for" (or less) was still in effect last time I checked, I presume there's a catch. My question is whether this is a usable if very basic no-frills sight, or whether it's basically a toy sight that isn't worth bothering with.
P.S. I've trained on fixed sights for basic target proficiency but I don't trust my night vision enough for low-light situations.
