I have been doing som stippling with a 5.00 Wal Mart 30w soldering iron. It has a length adjustable ball point tip which is all I use since it leaves a nice "pore" that sucks in skin. I have been stippling my firearms wherever its applicable and I have also stippled a surefire G2 and Gerber axe with great results. This would also work wonders on plastic hi-cap mags such as the Magpul Pmag etc...infact, it works on anything that is plastic. I also use Mob grip tape on top of the slide on my pistols to enhance my slide manipulation abilities. Grip tape is the only option since I wont dare take a hammer and a punch to any of my guns.
