id like more info on that alluminum casting.
I'll take a picture of one that I haven't polished and post it tomorrow,,,
Sorry but I don't have any pictures of the one I polished and painted.
Duncan Customs has what is probably the worst website ever built,,,
But if you call or E-mail them they will send a spreadsheet with the pistol castings they have in stock.
I haven't ordered one in over a year,,,
At the last order they were only $45.00 each.
It should be no problem to drill and thread a hole in the aluminum,,,
Or drill and insert some steel threaded collar if you think the aluminum would be too soft.
