Featuring the same design attributes that have made Harrison Design triggers a must-have on custom 1911s across the country, we are proud to release the newest Harrison Design trigger, the Tri-Cav EMP! The Tri-Cav EMP sets itself apart in style from the traditional H-D Extreme Service triggers with solid shoes, while still offering the same technical features you've grown to expect.
Three lightening cavities are machined into the trigger shoe to lighten it and give it a special appearance.
All Tri-Cav triggers are made with hardened stainless steel bows that are micro-polished to reduce friction.
The Tri-Cav aluminum shoes are oversize in height allowing fitting to the individual pistol.
The "B" trigger is treated with Black DLC coating, for an all-black trigger.
The "N" trigger is natural aluminum and stainless steel for an all silver trigger.
The face of the trigger shoe is smooth; free from serrations and holes for the over-travel screw that can chafe and abrade your trigger finger during long training sessions.
The fixed over-travel stop is permanently locked in place so it can't creep in and render your pistol inoperative in an emergency. The initial adjustment to the over-travel stop is made by filing and re-testing until the correct amount of over-travel is achieved.
Tri-Cav triggers are offered in long size only due to size constraints encountered.
This trigger does fit all models and calibers of the Springfield EMP & EMP4 pistols !
Note that fitting by a knowledgeable installer is required to install this part.
