Extreme Engineering Extreme Duty Sear

Manufactured from the same aerospace steel alloy as Extreme Engineering premium hammers. The Extreme Duty sear has been developed for those who need the finest tactical sear available. The sear is made from the same special die steel that our Ultra Match sear is made from. The tensile strength is 265KSI and the yield strength is 245KSI. The Extreme Duty Sear is heat treated to RC 50-53. The Extreme Duty Sear has the same heavy-duty full profile as our Tactical sear except for the legs. The legs of the sear have been contoured like the Ultra Match Sear. This improved contour provides a radiused contact point for the sear spring while keeping the strength of the sear at a maximum. This radiused contact point allows the sear to move against the sear spring with less friction. This provides a smoother sear movement and allows the sear to move faster during the cocking cycle. The increased sear speed during the cocking cycle allows a more positive sear engagement with the hammer. The smoother sear movement against the sear spring also creates a smoother trigger feel.  Fits Kimber, Springfield, 1911, STI, SV, and Para. Ultra Light Low-Mass Sear.
