 The Cammer Sear tip maintains constant distance of .404" from sear pin center.  NEUTRAL ENGAGEMENT with hammer hooks throughout sear movement to release.  Neither positive/captive (hammer is lifted with sear movement) nor negative/release (hammer lowers with sear movement).  CNC'd by Evolution Gun Works for Cammer Technologies.

Ready to install in your 1911 model pistol

• Sear tip maintains constant distance of .404” from sear pin center
• NEUTRAL ENGAGEMENT with hammer hooks throughout sear movement to release
• Neither positive/captive (hammer is lifted with sear movement)
• Nor negative/release (hammer lowers with sear movement)
• Yields smooth trigger pulls whether hooks are cut at 86 or 90 degrees
• No need for costly jigs or specialized stoning skills
• CNC’d by Evolution Gun Works for Cammer Technologies LLC
• All arrangements of 1911 sear and hammer hooks involve movement of the sear from beneath the hooks until release
• The goal is movement that is undetectable to the shooter’s finger
• Typical sears are stoned with flat primary and (most often) secondary angles
• These flat-stoned surfaces must move from beneath the flat hooks in an arc about the sear pin center
• Such configurations cannot achieve a preferred neutral relationship
• They will be either positive or negative—transitioning most often from one to the other
• Variables affecting quality of the final trigger pull with the .404” sear—and therefore adjustable by the custom pistol smith are:
• Height of hammer hooks
• Smoothness of engagement surfaces
• Sear spring tension
• Main spring weight
• The .404” sear is held in engagement by the forces of friction and sear spring tension
• Secondary/release angles are not necessary with the .404” sear, but may be added by the custom pistol smith as desired
• U.S. Ordnance specs call for sear length of .4045” - .003”
