1377 phase 1 with phase 2 or 3 grip frame?

Hello all, I have a 1377 phase 1 coming my way that I won on ebay. I can't find any wood grips that would fit the stock phase 1 grip frame. My question is does anyone know if the phase 2 or 3 grip frames fit on a phase 1 1377?

As far as I know there is no difference in the grip frames or grips on the 1377’s. I have an older 1377 with the rear pull back cocking knob from the early to mid 80’s and a newer 1300KT. The 1399 shoulder stock fits either gun so I don’t know why the wood pistol grips wouldn’t interchange also. Alchemy AirWerks sells wood grips. Some are finished and he sells ones that you finish yourself. He has an eBay store and you could ask him. There are other sources for wood grips out there for the 1377 also. Good luck
