I sometimes use a WML on my HD weapon (a Glock). I have no use for a WML on a carry weapon (sometimes a 1911).If lights on a pistol were such a disadvantage then why are they pretty much on every LEO and Special Ops pistols? If they were so bad they would have faded away long ago. Its all in training and proper usage. They are not meant for walking your way down a trail. They are used for target ID and as an added bonus temporarily blind/disorient your suspect.
I'll keep my 20 year-old Jeep, thank you. No nav unit or body control unit to get hacked into and no "black box" to snitch on me. I don't need a backup camera or lane-departure warning systems either..... my Mark I eyeballs work just fine. All this modern crap that's supposed to be better ain't necessarily so. I see the point of weapon lights if you're a SWAT entry team member, but in the civilian world you're sweeping everything you look at with the muzzle of a loaded gun. I have a WML that I once put on a pistol, but I've since taken it off and the thing is in a box somewhere. I think they have a more practical use on a rifle where you need both hands on the weapon anyway.If you have a good amount of 1911’s already and you need a true working version of it, would it be better to substitute a Glock instead so you could have a rail or keep your 1911 with a rail. Come on cavemen, move on from the Stone Age and allow some accessories.
Only if you use it at the wrong time...the light is fairly blinding besides.I think a rail on a handgun with a light tells the bad guy exactly where you are, before you see him. We see this stuff on tv but in real life situations to me it could be a disadvantage. The ratchety noise of a 12 ga pump may work better.
