rosebute It is the 1 & 1/2 lb model. Worked pretty good for a few years but always was "finicky" right from the start. Not consistent and would not maintain it`s setting. I know, I know, clean it with lighter fluid, do not over lube, run dry, use a little lock tite or finger nail polish to set the adjustment screws. done it all, nothing worked. Had to tinker with it periodically, mainly with the disconnector and reset, but was nice when it did run. A while back the disconnecter spring broke in half and it is a bit of a unique spring. I have tried every spring I have and/or can find to no avail. Have contacted Jard and customer service does not seem to interest them much. I have (and have had) Timney triggers in various other rifles and found them much easier to set up properly and none of them were high maintenance like the Jard, and have never had any issues with any of them so I am contemplating a Timney for the SR-22.
