i use ladders.
uncle sugar saw fit to issue me a rifle that had panels so that's what i used and it was fine. now that i don't "use" a weapon for my job things are different.
for the most part i shoot with gloves on so the added heat protection from panels isn't as much of a concern. the lower profile grip fits my hands better and looks good too. at the range or out hunting small critters the gloves offer protection from more than just heat. in a HD situation if i need to fire off enough rounds that the weapon gets too hot to hold then i'm screwed in more ways than one.
let's face it, looks play a part in things too. i don't NEED anything more than a basic M4 for HD/SHTF but having a more capable rifle increases my effectiveness. when i add these things to my rifle there is the added bonus of having them be visually appealing (to me).
YES, it's a tool blah, blah, blah. i don't NEED 7 hammers just like i don't NEED 7 AR's. some of what we do IS about looks. how many people complain about the purple colt's? would i care? yes and no. it's a colt so in theory it's fine, even if it's purple. the color would bother me and i would end up painting it.
so for ME ladders
WORK better (should be the primary concern) but also look good
