I keep hearing about this and that kind of lube for my Sig so I thought I'd ask here... what do you use on your rails for lube? I"ve never had an issue with my Springfield XD's but with the Sig I have. I've been using Hoppe but the last time I went to the range had two misfires. I would assume the Sig gets hotter than the XD's... All guns were just cleaned a week before heading there...Comments??
