Both triggers are priced the same.
Might fluxuate $10-$20 between the two. You have to look at the kit. Both triggers are sold in three kits. The whole marketing and design of the triggers are just copies of eachother. Its kinda funny.
But both pyramid and glockworx have the trigger bar; a complete kit with springs and a striker safety; and a ultimate kit that includes everything plus a lightened striker. Prices are approx $140, $170 and $250 respectively.
I'm in the same boat, I want to get another Glock to get one of these to see how it runs!
