Soon my Colt SP6940 will be in and I want to get an eotech site. I was looking at the exps3-4 (comes with 5x magnifier) that has the 4 dots calculated for ballistic drop for distance. My question is, in a SHTF situation, is that 4 dot pattern really needed? I think its cool and I would like to have it because I will be doing some somewhat longe range shooting with this but I just cant make up my mind if it is worth the extra cost, if it is needed, or if the 4 dot pattern will be distracting.
Im just looking for any and all input.
