IMO a 2lb single stage trigger will get you in trouble with unwanted doubling from recoil and if the sears are so short or the angles changed it could slip off the sear edge causing a mechanical malfunction.
Bill Springfield makes good safe triggers or will do a trigger job for about $45.
Your trigger could be fine but be careful with it until you are sure it is.
