I went to the Glock site today and saw this warning.

WARNING!!!!!

Danger: A very serious and potentially life threatening situation has recently come to our attention. An aftermarket trigger distributed by GunAccessories.com defeats the firing pin safety in GLOCK pistols when it is installed. The vertical extension on a GLOCK trigger bar is in constant contact with the firing pin safety once this trigger is installed. If a loaded pistol is dropped, it will discharge without the trigger being pulled.

If you have installed this aftermarket part, immediately remove it from your pistol. If you know anyone else who has installed this trigger, please notify them immediately.

If this part is installed in your gun, it can discharge if the gun is dropped or jarred. Obviously this will lead to an unintentional discharge and may cause serious bodily injury to yourself or another.

I posted this over in the Glock section of HandGuns. handguns.ar15.com/forums/topic.html?id=405

They ought to say it is the "Lightning Strikes" aluminum trigger.  The frigging thing bit me in my Glock 21, the trigger safety came loose and jammed int he open position (During a match), it was the reason I came in 3rd, instead of 1st.

The triggers feels great but it is a POS.
