Extreme Engineering LiteSpeed II Group – 5 Piece – SA Prodigy

Extreme Engineering LiteSpeed II Trigger Group (5 Piece) All 1911/2011 Competition Pistols -SA Prodigy

 The actual trigger on your 1911 has very little to do with trigger pull or feel of the trigger that you experience when shooting your 1911.  The feel and function of firing your 1911 is actually determined by the engineering and fit of your hammer, sear, disconnector and the correct selection of the main spring and sear spring.  A high price trigger with low quality fire control components will still result in a poor un-wanted trigger pull. 

Most OEM components are only induction heat treated, and cannot be stoned without losing their hardness on the edges.  this results in the trigger pull changing over time.

The Extreme Engineering Fire Control components, are truly space age.  They are manufactured from the same alloy that rocket booster engines are made from.  There is no need to stone them to fit or function, The hooks on the hammer are perfect, and there’s no reason to stone the sear either.  As a Drop In,  this kit will give you a clean 3 pound trigger pull.  With slight tweaking of the sear spring this set can be set for 2 1/4 pound trigger pull that is reliable and will not change. 

Extreme Engineering fire control components are the best Hammers, Sears and Disconnectors made in the USA.  All Extreme Engineering components carry a lifetime warranty against breakage.  The quality of the Extreme Engineering components far exceed those of the imported kits that are offered by others.

This set is for the 1911 competition gun builder/shooter who wants an ULTRA LIGHT hammer weight for the fastest lock time with a hammer with a thumb cocking piece and any trigger pull weight that they are capable of producing. Suitable only for match competition 1911 pistols.
