Finally upgraded my M951!

After a ton of reading, I went with a Solar Force XM-L for my Surefire M951 as well as a Lumens Factory D26-LED for another. The Solar Force is noticably brighter in person than the Lumens Factory bulb. I bored the head out with a Dremel to get a nice tight fit after removing the spring that came with the bulbs. Could this possibly cause any problems later down the road? Here are the pics. It's not as blue in person.

Thanks for all the help guys!:thumbsup:
Just need to find one for my M961 now if anyone has a recommendation.

Check Malkoff. I like his set-up. Bright & reliable. We all grind a little here and there. I usually try to grind the cheapest part (if possible). Malkoffs are potted and can take recoil.
