The other day I was cleaning my 4013/4010 and a 4516-2 and wondered if the 4010 slide would go on the 4516-2 frame and it did. Of course the mags won't work so then I thought, how about putting the 4010 slide on my 1066 frame. What do you think? Will it shoot? Sure would look cool. If I get positive responses, there will be pictures.
