Fisrt off I debated if I should post this in the semi-auto pistol forum or in the accessories forum but decided on here so move if needed.
I'm asking because I shoot a Glock 45 in USPSA Carry Optics and the rules changed in the last year or so to allow people to use a pisotl light if they want to. A lot of people are gaming it putting the heaviest light they can on it (The Lok brass light is the gamer light of choice as it's basicalya 7oz chunk of brass) and the gamiest pistol light seems to be the TLR-1 at 4.1oz
And this kind of led me to this post asking the question is 4oz of weight out front really going to change it that much? Do you shoot better with a pistol light on your gun?
