    Things I liked:

    Accuracy. Re-creation of the firearm realistic. MP-40 is robust has the weight and feel. Original 8 3/4 pounds.

    Things I would have changed:

    Nothing.

    What others should know:

    There has been complaints of difficulty in loading the magazine. There is no way of improving the stock loading process. If a larger follower button was produced, there would have to be a vertical grove milled in the magazine well. That would certainly up the price of the "firearm". You can solve this problem of loading by buying the bullet pen. I use one on my M712 by Legends. I also use it for loading of the MP-40 magazine. Buy an extra magazine. There have been complaints concerning co2 cylinders not being punctured. Well, I find it a pain to send back a magazine that doesn't function properly, and you just might get a replacement that would also malfunction. I took the advice of another reviewer and placed a washer in between the c02 cylinders. Works great! I might add, the MP-38 and MP-40 were full auto only. Semi, a nice feature (not accurate), Finally this is an MP-40, not an MP-38 for obvious glaring external differences. Not enough room here to explain.

    Excellent service and thanks Pyramid air ! The quality of the Legends MP -40 is amazing ! My only issue is loading the clip , THAT design needs to be addressed that's my only problem with the MP- 40 . Legends mp 40 is a fantastic in every way !

    Things I liked:

    It is just a barrel of fun. Semi and full auto modes worked great. It is a robust CO2 BB rifle.

    Things I would have changed:

    none

    What others should know:

    Buy tons of CO2 and BB's because once you start shooting it you will not want to stop. Buy extra mags. I thought 2 mags would be enough for this beast but for full enjoyment you will need 6. This will allow the CO2 cylinders in each mag to warm up and be ready for the next 52 rounds.

    Things I liked:

    Build quality and materials are excellent. Historical accuracy is very good. Fun to shoot, especially on semi-auto which extends CO2 life. Accuracy very acceptable for a bb rifle. As a package, theres nothing like it. A must have.

    Things I would have changed:

    Without a do it yourself spring holder, difficult to load I only wish Umarex would put a little more thought into the loading of their full auto Legend series like the MP40 and the C96 - very difficult on both.

    What others should know:

    Quite fussy as to the bbs. Mine kept jamming with copper clads. Use a high quality polished steel to avoid jams.

    Things I liked:

    Far better than I expected. The all metal construction, weight and function make it a thrill to shoot. I've fired a real MP40 and I can say that it is the next best thing.

    Things I would have changed:

    An extra mag would be nice, even if the price was a little more.

    What others should know:

    Run a litley oiled patch down the barrel before firing. The barrel can't help but be a bit dirty, plus it will slide those steel bb's out just a tiny bit fast, not a lot, but any increase is a good increase.

    Things I liked:

    Very rugged and realistic looking, even more so than the new 9mm replica.

    Things I would have changed:

    Mine would not pierce both bulbs, just one. I fixed that by placing a small washer between the two.

    What others should know:

    Gas hog...Not all BBs will work in this gun...Most fun per dollar.

    Is awesome gun. Identical to real one.definitely..was a great birthday gift.

    Things I would have changed:

    The name this is not a mp 40 is a mp 38. The 40 all is black the 38 was bakelite brown

    Is a awesome gun.

    Things I liked:

    I love everything about this gun! Right out of the box, CO2 cartridges worked fine, BB's are very easy to load, the sound and feel is great. I's what I called today a squirrel chaser. I'm very happy...squirrels, not so happy. Personally, I think this is a great deal. I just wish I had purchased it Christmas time when they had so many great specials going on. This gun is just for fun and chasing squirrels. I do own an Impact FX and a newer Impact X and an Umarex Gauntlet which I love for hunting and target shooting. This gun would never be a good fit for hunting or target shooting, so just know...it's a fun adult toy. I'm 64 years old and thrilled to use this and let my inner child come out with those "wiley waskels".

    Things I would have changed:

    NOT ONE THING!

    What others should know:

    Pyramid Air are great to deal with. I had an issue with the first one I received, sent it back and within a weeks time had a replacement in my hands. They are a very proactive company and obviously value their customer base. They operate like we do which is customer service is just as important as selling a good product.

    What others should know:

    Never got to fire it. Mine was defective, I returned it after trying both magazines. They would not pierce both c02 cart, only one and then the gas would all escape. Never got to fire it, too bad. They are exchanging it for comp priced break barrel with a .22 cal magazine.

    Things I liked:

    I like pretty much everything about the umerex mp40. It's got a great feel to it, it's accurate & easy to load but I think the clip could use a little more work. I've used several different makes of BB's &I can't get it to empty a magazine with out a jamming issue or two per magazine. I've ordered another one with the hopes of getting one that doesn't jamm. Hopefully the new magazine does the trick.

    Things I would have changed:

    The mag is a 52 shot mag but they recommend that you load it with 40 to 45 shots. That hasn't helped me any. It's a double stack mag when you put tension on the BB's it forces the BB's into the side of the mag causing the BB's to interlock & push into the sides of the mag. I've tried literally everything including lite lubrication. I think they should have put a coat of Teflon on the inside of the magazine.

    What others should know:

    I've found that the black diamond BB's work the best. They are coated & create less friction.

    Things I would have changed:

    I wish the grips weren't plastic, but apart from that, nothing.

    Everything.....this thing is awesome.....if you take just a little extra time loading the magazine it won't jamb up at all. I've had no problems with that.

    Things I would have changed:

    Nothing...... i wish i had bought the sling....maybe can but it separately....

    What others should know:

    Only problem i had was after about 600 rounds the valve at the top of the magazine started leaking so i have sent that back to Umarex.

    Things I liked:

    I purchased the MP40 with the weathered looks and sling. It is a great weapon and so much fun to shoot in full auto. Heft and feel are very authentic.

    Things I would have changed:

    Nothing.

    What others should know:

    Buy it just for the historical nature behind the weapon, and its a great blast to shoot. I Fire it in short burst like I did when I carried a BAR in the Marines.

    Things I liked:

    This gun is a blast, I took it to a range that has real full auto and they were impressed with the attention to detail of this gun.

    Things I would have changed:

    I would include a magazine load to ease the loading of bbs, I made one out of wire and a drinking straw.

    What others should know:

    Use dirty bird targets, give great reactive feedback.
