I have had good success with the first batch of sear springs, and have expanded my product to include 2lb & 3lb sear springs. We've done extensive testing on both springs and find the spread to be +/- one ounce nominal. Tests conducted using multiple springs and multiple passes. I've lowered the price to $5 and no minimum order. You can find them on eBay or my website http://springs.ccskeet.com.
I know you'll like them. They're the cheapest answer for your trigger pull weight around. Only $5 shipping for up to 10 springs. So mix & match and buy some for your buddies...
