My #1 has a replacement trigger, the Kepplinger set trigger. And they are GREAT. About 2 and 1/2 pounds unset, ounces when set. Comes with instructions that you can probably do yourself. Mine went to the smith, cause it was getting rebarreled anyway. It's a single trigger, to set it you push the trigger FORWARD to the 'set' position. They are a bit pricey at around $175 from Brownells, but i'll trade in my 40 pound trigger for one of these every time I get a #1.
Have Keplinger trigger also. Unbelievable! A bit pricey though. Have another with a Mowry which I like but it is not in the same class as the K-trigger. Didn't know that Canjar was makin' those, thanks for the tip!
