Bright and easy to use - Streamlight TLR-1 HL LED Weapon Light Earless Screw w/Batteries

Used on G19 gen 3 and was surprised even with my short fingers the tab was really easy to activate with either my trigger finger or my off hand thumb. Front weight did seem to be an issue as I hardly even noticed a difference. Bigger than some of the other lights currently on the market, but couldn't argue or beat the price point at time of purchase. So far very pleased.
