M3 Grease Gun and HK UMP

hey brother a little bit of blastin here good to see I see you got the grease gun out yeah a little piece of history here today they're the m3 submachine gun is commonly referred to as the grease gun bowing to its visual similarity to the common mechanics tool the m3 is comparatively low cyclic rate was a function of the relatively low pressure generated by the 45 ACP round a heavy bolt and recoil springs with a lighter than normal compression rate the m3 fed from double-column single feed detachable box magazine which held 30 rounds and was patterned after the British Sten magazine brought out what you and I both consider the modern-day greasy oh yeah the 45 UMP you're right the modern-day counterpart the UMP is a blowback operated magazine-fed submachine gun firing from a closed bolt this one fires in 45 ACP but it also comes a 9-millimeter and 40 Smith & Wesson the 45 version is specifically meant to bring more punch than a nine-millimeter mp5 most submachine guns feel heavy for their size a quality that helps with recoil when firing on full auto but the UMP is different it feels pretty lightweight and it's actually kind of bulky for a submachine gun the counter the lightweight of the gun and still keep it accurate on fully auto HK reduce the cyclic break down the fire roughly 600 to 650 rounds per minute it actually could have had a much higher cyclic rate of fire than that operationally lighter is usually better than heavy as long as performance doesn't suffer I think the UMP succeeds here just like the grease gun the UMP was meant to be a more cost effective weapon than its predecessors the grease gun was meant to replace the Thompson and the UMP was designed to replace the mp5 now one of the things I want to talk about today is the similarities between the UMP and since you've got it here the grease gun oh yeah even though they really came from two needs and necessities that both really this is without a doubt you and I agree the modern-day version of the grease gun itself absolutely but the parallel of application is so similar it's it's pretty impressive with obviously a probably a far superior gun right but my rolls they feel or pretty much very similar very similar and then very simple gun easy to manufacture much like that one exactly and of course also inexpensive yeah as we know when this gun was developed it was designed to replace the expensive Thompson submachine gun so as far as the money involved in the manufacturers you know it's all stampings look pretty crude looking at the matter of fact you know got the nickname the grease gun because that kind of what most soldiers thought it looked like extremely rugged you know one of the drawbacks 8 pound empty what's the weight on that that's about a five pound gun because of the polymer because of the polymer yeah eight inch barrel Retin that's about the same the UMP is about the same 450 rounds per minute cyclic rate this one's about 650 the one thing this has going for it that does and this is select-fire semi ER full auto you both done you can do that with the grease gun but you have to get off that dray exactly you got it's all trigger controls all trigger control and we could certainly argue you know one of the troubles with a grease gun is basically to load it specially originally in three you get a cocking lever you [ __ ] but at this point to make it safe the only way you could really do it was retract the bolt slightly close the dust cover which lock the bolt and that was your safety right that and you and I both know it's a little hokey that's common recipe for an ad as a matter of fact most soldiers carried the gun with the bolt forward a loaded magazine in place and the way they put the gun into action of course you had to open a dust cover but the way they put into action was reach up and grab the charging up and charge it so thoroughly a slower gun to put into into a fire mode than say a modern gonna like the UMP well one thing I noticed you've got an original m3 not an m3 a1 which is somewhat of a rare gun yeah as a matter of fact clearly there was problems you can imagine in combat these things often got bent dropped or banging into things and they realized that was a bit of an issue so the lovers basically did away with me went to the m3 a1 which basically had a big hole in them and the bolt and the way you talked it you put your finger in pull it back and cockpit which by the way when your hands are cold or wet muddy bloody that was a recipe to disaster if it slipped off bang at an Asian Chow and then on top of that they also had that little l-shaped piece of metal that helped you load the Magna charge the magazine now one of the interesting things about the early like model like this is you know is really the front of the of the stock is actually threaded there's actually a threaded array you can actually put a clean brush in it and clean your barrel used when you would took the stock off it had a double application really a pretty cool gun despite the fact it had double column magazine and went into single position feed much more reliable than people get a credit for and was in service longer than any other submachine gun in US history by far most people don't realize particularly within the armored core the m3 grease gun was still in use for example up to the time of the first Iraq conflict one of most of the m1 Abrams actually still had to hand them grease guns in them as the gun that the armored troops they used had to fight off troops at close quarters which is pretty cool yeah
