Thank you all for the information. Sorry it took so long but got shipped out of town for a few days. With all these details I belive it is an un modified 1922 except the stock has grooves in the foregrip. I do not have a magazine for it so that is next on my agenda. Hence the reason for wanting to identify it. I believe each model had a different one. Any idea on where to start looking for one? Aftermarket would be fine for now but I would like to find an original eventually just because. Thanks again for all of your help!
