SVI hammer/sear engagement

Recommended Posts

I had a customer with a custom build with SVI parts, I looked at the hammer/sear under a microscope and noticed a strange engagement...

 

normaly the tips of the hammerhooks rest on the primary face of the sear, and you cut a secondary angle.

on this gun the searnose was smaller, had a small primary cut and a large secondairy. the hammerhooks were as high as the searnose.

so the sear has to travel a verry small distance.

 

this was not a factory SVI so I don't know if this is standard

Was probably done on a Power Custom fixture, which allows you to adjust the angle and width of both the primary and secondary surfaces.  Less engagement is not a problem as long as it's done properly and passes all function and safety checks.
