At least that's what the manufacturers of on-weapon light systems would like you to believe. I learned how to shoot in low-light conditions before there were on-weapon light systems. While I'm never one to stand in the way of progress, I don't see on-weapon light systems as progress. I see them primarily as another gadget that very few owners take the time to learn how to use properly ... let alone practice with on a regular and frequent basis. YMMVThe light held away from the body - the FBI method is tiring and hard to align with the gun.</p>
I have a Surefire 92FS adapter for my 92FS and love it. I carried my M9 w/ a Tick rail back in 2006 and it worked good, but I prefer my Surefire rail over the Tick. I'd give it to you but it was lost during the several moves I've done since my deployment in 2006. The Surefire rail is a bit more expensive, but I think the cost is worth it. if you're on a budget, the Tick will suffice.
