Bill, The 1922M1 magazine and the M2 Rifle magazine look exactly alike. The difference is that the M2 magazine is slightly longer thus extends slightly higher into the receiver. They both fit flush with the floorplate. The M2 magazine is marked on the upper left side with a small M2. The 1922M1 magazine is unmarked. Either may be found blued or parkerized. The M2 bolt must have an M2 magazine and the 1922M1 must have the 1922M1 magazine. An original 1922 magazine will work with a 1922M1 bolt but you're not likely to find one. The 1922 magazine does extend some half inch or more below the floorplate and it will not have the three little teeth on either side as do the 1922M1 and M2 magazines. If your rifle has the M2 bolt (bolt will be marked M2), then you will need the M2 magazine even if the bolt is in a rifle with receiver marked Model of 1922M1. Expect to pay $100 for an original magazine. They come up regularly on the internet auctions. Make sure you get the correct magazine as they are NOT interchangeable. I may have given more information than you need but some explanation is needed. There is a lot of misinformation posted about the 1922 series Springfields. Some even refer to the M2 Rifle as a 1922M2. I try to avoid using the designation 1922M2 as there was no such rifle and not giving the correct nomenclature sometimes causes confusion as what model is being discussed. Lastly, I have never tried one of the aftermarket magazines now available but have heard that they are not reliable. There is an M2 Rifle magazine listed on gunbroker. Do a search for M2 Springfield and will find it. The picture clearly shows the M2 marking.
