There are two ways to reinstall the mainspring in relation to the hammer.

One will cause light firing pin strikes--particularly in DA.

Find a website and verify that you have reassembled the gun properly.

It's hard to describe without pictures, but the shorter fork of the mainspring is probably in the wrong place.

I'll write what I have in my own notes to myself on reassembly.

Install the firing spring (mainspring). Take care to insure that the firing spring mates properly with the lever (trigger bar) pivot. Both stems of the firing spring should contact the hammer, NOT the lever (trigger bar) pivot. Note the position of the small firing spring fork in the figure below.

The figure below (which I can't draw here) shows the trigger bar pivot (the swinging dohickey on part # 7 in the Bulgy Mak manual) with the short stem of the mainspring positioned between the pivot point of the trigger bar pivot and the first protrusion on the side of the trigger bar pivot. Not in the little channel formed by the protrusion and the protrusion at the swinging end of the pivot.

Sorry for the poor description in place of a figure, but I don't have a scanner.
