Grippy trigger was what i was looking for - Geissele Super Tricon Trigger

This trigger has a fancy name, but it's really identical to the Geissele SSA with the only difference being the shape and feel of the trigger bow. But for me this upgrade is exactly what I was looking for. The straighter curve and addition of a grooved surface give a lot more area for placing your finger where you want. Lower placement makes the trigger pull feel lighter. Also, the grooves are a little grippy so your finger doesn't move during the trigger pull even if a bit sweaty. A lot of 1911s have a trigger shappe and feel like this, but this is the only one I found for the AR-15.

For the trigger pull itself, I also really like it. This is a two-stage design with a relatively low trigger pull weight. The result is there is a bit of safety built in with the two stage pull, which is ideal for a home defense or battle rifle. A single stage hair trigger is great for target shooting, but can easy result in a negligent discharge in high stress situations. The pull weight is low enough and the break is clean enough that it is still a major upgrade over the standard mil-spec trigger.
