I had the pleasure of shooting an MP40 a while back and now think I'd like to get one. What are the major things I should look for when considering one?

Thanks

A lot of the ones for sale are not really mp 40's.
They are built on registered tubes with a collection
Of parts.

Im guessing your talking about a tube gun..

From what little knowledge I have on them
They use the same style mags as the STEN so they can jam here & there but for around $20 per mag you can stock up as many good mags as you want.
Make sure none of the plastic is cracked
Try the stock to see how much wobble is in it. Folded & open.
Best thing to do is ask to test fire it.
Then take it apart & see if anything is worn down.
Ask the owner if he/she has had any problems with it in the past. Most NFA owners are very reasonable people to deal with.
Good luck

Thanks for the reply Fairplay I found it useful. That explains why some of the MP40 are lots cheaper that others. I would not want to own an MP40 franken. I would rather just have the stemple or sten for a much lower price rather than that of the clone.

I wouldnt say a lot of the tube gun MP40s are franken guns. Most if not all the tubes are better built and of better steel than the quality of an original. When put together, you'd be hard pressed to distinguish and original mp40 from a tube gun,

do the composite lowers ever crack on these guns? I have always been wary of that considering the price.

I have an MP40 and the mags are a lot more then 20 dollars. They are more like 75 to 100 each. They are a blast to shoot though.

I'll second that- please tell me where I can buy MP-40 mags for $20. I'll take them all.

The MP-40s that are original German military manufacture are Curios and Relics, so in some states they are the only MGs you can own. They cost more, as they are the "real deal" and some folks will pay more for that. I own a tube gun made on a Wilson tube, and it runs with almost boring reliability. From the outside you really can't tell it's not original unless you get really close. The only functional difference is that the original tubes were "corrugated" to provide slots inside the receiver for dirt to accumulate. The tube guns were made with regular tubular receivers that have the appearance of the stamped ridges machined onto the outside, so if you look inside the receiver the grooves won't actually be there. Unless you are planning on invading Russia, it won't matter.

The plastic parts will crack if you do something silly like drop your MP-40 onto a concrete floor. Otherwise, they are fine. Parts are getting more difficult to find, but it's such a dirt-simple mechamism that there really isn't much to break. It's even simpler than the Sten, which has a select-fire feature. Replacement extractors are being made, as are replacement spring sets. If you buy a bolt and spring assembly from IMA from some post-war subgun (who's name escapes me right now) then you don't even have to worry about firing pins and you can put your original bolt away.

The stocks do tend to wobble, but there never was a Hollywood Nazi that ever used the butt stock anyway so you just leave it folded up while shooting. If the wobble really bothers you, a good gunsmith can carefully pull it apart and do a little TIG welding to remove the slop.

Sten mags wont work in an MP40, at least from what Ive seen attempted. Mainly a pain in the ass to deal with.

Nope- different dimensions. Sten mags and MP-40 mags are not interchangeable

They are the same "style", in that they are double column, single feed magazines which mandate the use of a loading tool to load up..

Dedeye, try Long Mountain Outfitters for mags at http://www.longmountain.com/store/magazines/?productid=380&continueShoppingPage=%2Fstore%2Fmagazines%2F%3Fstart%3D12%26categoryid%3D74%26keywords%3D%26searchwords%3D%26itemNumber%3D%26searchPriceRange1%3D%26searchPriceRange2%3D
They are listed as MP 40 Magazine (converted from a Hotchkiss Universal Magazine) 24.95 each. I bought 4 for my MP40 that with luck and a little help from the BATF should be released from my dealer's safe sometime in July!
No, I haven't tried them yet.

Thanks for the link, but I have a hard time thinking of those things as MP40 magazines. Thankfully I have a good supply of the "real deal" for my baby.

I mean- they might work, but daaaaaaaam they're ugly. Somehow those things conjure up visions of a Victoria's Secret model "converted" from Rosie O'Donnell.
