Sometimes 1911 frames can be a bit out of spec. One of the more common issues we have seen is the sear spring slot cut lower than it should be. This can cause the sear spring to not fully engage on the sear. Many springs currently on the market are not long enough to address this issue. We went back to the drawing board and made our spring over .030″ longer on the left finger to accommodate frames that encounter this issue.
Above Image Details:
Detail A – The left side of the spring has a relief cut to allow for the spring to move without contacting or rubbing on the frame. This ensures a smoother, crisper trigger pull.
Detail B – The sear pad on the left leaf is less than 1/2 the size and weight than other sear springs, thus reducing the weight for recoil or inertia to act upon.
Detail C – The center and right side leaves are 5% narrower to reduce weight and increase feel.
Detail D – The disconnector pad on the center leaf is smaller than other sear springs to reduce weight, while still retaining the standard contact.
Please Note – We do not glass bead or sandblast the sears after heat treat. The heat treating process leaves the springs with a spotty finish. This is not rust and does not affect performance in any way.
