Here is your chance to do the board a favor.

While you have this gun apart, please look for holes bored oversize or askew, signs of improperly hardened parts, and evidence of peening.

I had a 209H for a time that was a little later vintage than this one, but had ... problems.

Take some pics if you find any evidence of premature wear, and post them here.

TIA


Out there doing it best I can.
