Hahaha! You can never have too many flashlights!
My current "short list" includes a Malkoff drop-in for my Surefire Z combat light, a turn-key Malkoff and a Surefire EB1. I'm also itching to get one of the new Streamlight weapon lights with the bumped up 650 lumen rating. Right now I have a Surefire X300 Ultra on my FNP45 Tactical, and it was the king of the hill for what, six months, before Streamlight came out with a brighter one? The new Streamlight will go on my Remington 870 and I'll keep the Surefire for whichever sidearm I'm using for HD at the time.
I gotta lay off the HK's! Flashlights are bad enough, guns are even worse! A few weeks ago I found a used USP9 that you seriously can't tell from new; it was only $699! Not a bad price at all. So even though I didn't strictly need it I couldn't pass it up. Now I have two USP9's! I have a P30S on layaway but that's gotta be it for awhile. Only exception would be if I was to find a HK45C somewhere.
