My byf 41 4877 v came to me with an unstamped aluminum bottomed mag. Can you describe what characteristics will enable me to determine if this was likely to have been the mag that was issued to this pistol? BTW, the pistol is almost MINT condition, with a mint bore, some holster wear on the sight, a bit on the sideplate and on the heel of the backstrap next to the lug. The finish is the "dipped" black look and is NOT "restored". Years ago I picked up a mint fxo 37 mag for it since the Black Widows I saw at that time had that type mag.....maybe I was too smart for my own good....the good news is I KEPT that mag and I would like to know if this could be the type you described.
Yes, the grips are black plastic, yes it has the threaded holes on the back, but no, the threads are over twice the size of the grip screws. They show some wear and have been like that since 1976 when I purchased it. The PO had it some 10 years I believe.
