I assume forward is the position the piston is forced into when the slide slams forward into battery.
When the gun is fired the piston cycles and then returns to its forward “stuck” position.
I would fire a few mags through it and then pull it out of the stock and see if the piston will move.
My 442-1 is sportin a set of Crimson Trace 105s,
I carry it in a Kramer pocket holster.
I like the Bianchi 6 round speed strips,
I carry my 442 stoked with Remington 158 grain LSWHP +P
It shoots a little high with this load,My 148 grain DEWC at 750 fps handloads shoot to the sights pretty much
Good call,
Just my opinion,but if it was a gun my dad had left to me ,I wouldn’t erase all of his history carrying that gun by refinishing regardless of how worn it looked,the more worn the better imho.
Edited to remove mushy sentimental comments.😁
I would strip the tru oil and just buff them to a very high gloss using progressively finer grits of paper finishing up with paste wax,
Cocobolo ,which I think your stocks are,which is a specie of Rosewood,does not take or need a finish,and that is probably why the original finish was flaking off.
A previous owner may have replaced the hammer and failed to get the sear fitted correctly.a double action sear that is a whisker too long can lock the trigger up in the beginning of its stroke.
