Another hundred rounds of Lucky Gunner's .357SIG ammunition got sent downrange yesterday morning in the ongoing effort to make the Surefire XC1B say uncle.
Also seen in the picture is a review gun for an upcoming Shooting Illustrated piece.
Four back-to-back mag dumps of .357SIG leave the slide too hot to touch, for what it's worth. The XC1B continues to work, and the mounting screw hasn't loosened.
Yesterday's shooting brings the total round count on the light to 750 rounds. There's another three hundred rounds from Lucky Gunner yet to go, and if the light's still running after that I'll just have to bolt it to my Glock 29 or something. If .357SIG won't do the trick, maybe 10mm Auto can.
