Is this Grip frame an M1A1 or a 1928?

http://www.gunbroker.com/Auction/ViewIt ... m=96700284

Seller says it is a M1A1 but it looks like a 1928 from the fire control levers not being the simpler pin design. It is marked Savage though.

Anyone have experience with the IMA dummy receivers? Are they static or does the bolt cock?

Thanks

That is the M1.

The 28 has the cocking handle on top of reciever. Looking at my 28
at least. hehe. As for the selectors? think it's just the savage version there where couple different contractors producing these during WW2.

As the receiver is stated as being a dummy version, could the upper be the M1 and the lower be from the M1928A1, as the levers match the 1928, as shown here:

So could a M1A1 receiver fit on top of the grip frame?

Yes that could be the case. I do know the actual M1 's are getting rather scarce these days, at least in the US. With the stupid deact standards we have.

Your are in California. I don't recommend doing it.

that's definatly the 1928 the levers are different and the back bottom section that is hidden by the stock ,but exposed on the m4a1 in pretty different

Just to throw a wrench here over on gun broker # 97753584
is an early M1 with the same levers. So it is possible that it is accurate.

Here is the "wrench" I was refering to.

I am not saying it isn't a 28 but there is this. A M1A1 on gunbroker
class 3 for sale land it's got the same switches. It is possible that this one also is a 28 lower on a M1 upper but would think to pull that off on a ATF form would be a major pain.



With the amount of these firearms produce in the span of service it is hard to say 100% sure that there where not part sharing and swapping.

Note the top of the grip - the M1A1 has a notch cut out at the back to locate the grip against the frame. The top of the '28 grip is flat. If you can find a pic of a 28 frame without the grip you'll see there's a chunk of metal left inside to keep the grip straight and a correspoiding cavity inside the wood. The design was changed to simplify the machining for mass prioduction.

Hence '28 and M1 wooden grips aren't interchangable.

It's possible the levers were also simplified for mass production later in the production run.

The lower receiver on that dummy build-up has a serial number consistent with that of an M1A1, but the selector switches (fire control levers) of an M1 or earlier. They were probably replaced at some time or another.

All 1921/1928A1, M1, and M1A1 models use basically the same style lower receiver (trigger group), and all are physically interchangable with one another. The 1921/1928A1 however has a couple distinctive differences only found on those models, including different mounting surfaces for the hand grip and shoulder stock.

All 1921/1928A1 and M1 models use the paddle type selector switches and 'floating' firing pin in the bolt. The M1A1 was intended to be a little bit simpler in design to cut production time and costs, which included changing to the pin & barrel type selector switches and a 'fixed' firing pin as part of the bolt.

Both M1 and M1A1 model upper receivers are completely interchangable with one another. The 1921/1928A1 model upper receiver however is unique only to themselves, and were the only ones capable of accepting the infamous Tommy Gun drum magazine.

As a point of reference, there were a total of 1,244,194 units made by Savage Arms from 1940-1944. This includes all 1928A1, M1, and M1A1 models they produced.

I've had two M1 lower receivers with paddle selector switches whose serial numbers were 62,XXX and 79,XXX. I also had a lower receiver of unknown origin with pin & barrel selector switches whose serial number was 94,XXX. Lastly, I've had two M1A1 lower receivers also with pin & barrel selector switches whose serial numbers were 159,XXX and 165,XXX.

The fact that the lower receiver in this auction has a serial number of 290,XXX makes me believe that it was originally attached to an M1A1 upper receiver, and the original pin & barrel selector switches were swapped out at some point -- perhaps during restoration. Locating the correct switches (both for the trigger group and for pulse rifle film accuracy) and replacing them is a relatively easy fix.

Although I've never seen the dummy receivers IMA uses on their display units, I highly believe that it is either a solid piece of steel or aluminum (probably the latter), and contains no bolt or firing pin. It will however typically have a hole drilled in the side for the charging handle to seat in a fixed position.

Hope that helps to clear things up some.

Thanks

Wow.

Thanks for all the info. An Incredibly informative lesson/history of the M1A1.
