Criminally overlooked. This thing was used for a very long time, up to the Iraq war, where it was gun to tank crews as defensive small arms. Sure, it shoots slower than the Thompson, but this gun knows how to put in work.

i remember seeing these being issued to drivers in my unit in germany in the late eighties

Anyone over 21 who can recite the constitution should be issued one free of charge from Uncle Sugar. I think we'd have a revival of informed citizens.

I was in an army artillery FDC unit in Germany in the 1970's. While we were issued M16A1s (has to be the crappiest weapon ever fielded) we had to train with the M3A1's too. I can't recall exactly why... Maybe for vehicle drivers of which I was one. But, I'd have to say nobody was ever under-gunned with the M3A1 and 1911A1.

I served in Charlie Co. 4th Recon, 4th MarDiv Reserves....the M3A1 was our principal T.O. weapon.

I was in the Field Artillery and we had them in the service battery section for the mechanics. This was in the 90s

1990-91: I was with EWC Team-1 with the 1st Marine Brigade, Deployed to Saudi Arabia just a couple days after Iraq's invasion of Kuwait...while positioned up near the Saudi-Kuwait border, Army mechanized units rolls past this truck stop we had pulled over to buy some stuff, this Army unit fresh in from the states pulled over as well, and to my surprise, a few of the Army guys exiting the APC's and trucks were armed with M3 SMG's....

These need to be more accessible to law-abiding Americans. Oh, & I don't know about the designing, but the Inland Division of G.M. didn't make the M3, it was the Guide Lamp Division of G.M. that did.

-In 1982 in the Malvinas War the Argentine Army used against the English a version of the M-3 called PAM-3 In caliber 9x19mm, this submachine gun was manufactured under license here in Argentina by Fabricaciones Militares (FM) for many years, but the first came along with the M-4 Sherman tanks purchased from England in 1947

I wish we could abolish the NFA so the American people could easily own these American classics .

"and all that for the low price of $20" Priceless!

I wonder how HOT that finger hole on the bolt gets??

Simple, cute but deadly. Genius engineering & invention.

Was on the M60a3 MBT and it was issued to as my main weapon and the 1911 also.

The Philippine Marines refurbished this gun from the reserve stockpiles and introduce a number of improvements. Check out their video

Some guns had an extra thinner suppressor screwed in front of the thick one.

Anyone have a full set of blueprints, including specks for the metal and springs tolerances? Hoping you all happy days in the sun on the banks a river.

Had one allocated to my M-60 tank in the Corps. This was 1990.

Was in an infantry company in 1997 and remember seeing some of these in our armory...they were around for a long time

Still used in the philippines with laser sights and silencer

We had several original M3 in our NG armor unit right up until we deployed for Desert Storm

My late brother while in Vietnam acquired a Grease Gun. He didn’t trust the M16A1. I know the Idaho Army National Guard tankers had them as late as 1992.

I loved shooting the M3A1, more accurate than most people give it credit for.

I’ve heard that some tank units had m3a1s in the invasion of Iraq

Weapon used by legendary Green Beret, Jerry "Mad Dog" Shriver...

The silliest part of the NFA is we viciously prohibit older submachine guns that don't fire any faster than your trigger finger could fire it .. why doesn't the NFA only apply to guns like the MG42..stuff with an incredible firing rate .. Far beyond what a human can fire at

It’s very simple but man does it look awesome

The M3A1 is one of the most beautiful guns ever made.

All the way up to the 90's, holy crap!

It seems really appealing with a suppressor being a pretty tube-shaped firearm and being chambered in .45 ACP Also, why there no comments?

3:56 check out that carbine! Nicely modded for jungle combat

I remember the little green plastic toy army men carrying these.

one of the weapons used to kidnap and kill high-ranking TNI army officers during the G30S incident

When I was in an infantry unit in Germany in 1978 they gave grease guns to mainly mechanics, and I think soldiers with other noncombat jobs, like maybe cooks. I'm wondering how the M3 compares in range to a Thompson. I know the Thompson has a higher rate of fire. If I was an enemy it would scare me to see all those .45 rounds coming at me. I'm thinking the Thompson probably has a better range, too.

If you can't find an M3A1 to fire in the U.S., you can always fly over the Philippines and visit one of their military bases; the AFP still fields M3A1s (but with integral suppressors and accessory rails) in active combat.

I always wanted one since i was a kid . saw one again in the army in the armory told the drill Sgt grease gun he said how do you know i told him ww2. Mel Gibson attack force Z. He said your right .we then went through the m16a1 rifles checking them out for service he showed me once and we them went through 70 rifles in 60 minutes good to go lol

In 1994 we had 4 grease guns in our TOE for our recovery vehicles drivers. We didn’t have any .45 ACP, but we had the grease guns.

I was issued a grease gun in the 1990's as a crew member on a tank recovery vehicle in the national guard.

Last century I saw a legal version on display. It was semi auto and the wire stock was permanently fixed. It came with a 16 inch barrel for shooting and a dummy 10 inch barrel for re enactments.

Let's push to abolish the hughes amendment .. and make these and other interesting pistol caliber SMGs more available to collectors

Repeal the NFA

I would have been so pissed if I would have been sent into combat with that.

It’s like if the Tec 9 was a rifle from the 40s withought the holes

is it me or does that kenneth guy look like burt reynolds

We still had em in Korea back in 95 but when we got our new tanks we got new weapons. LTC Antal carried one.

I still don't get why they didn't just drill a hole, thread it and stick even a simple bolt on it for a charging handle. Hell even a welded charging handle would have worked well enough

My brother who served a year in Vietnam told me me acquired a Grease Gun as a personal weapon

Amazing gun.

Ahhhh! Need more full auto suppressed!!

REPEAL THE NFA LET AMERICA OWN TANKS AGAIN

He right I was in the National Guard in the 80s I was issued one when ever I was assigned to drive the tank retriever.

Small, simple but greasefully dangerous

Why are they so rare if there were so many made? I got my first Action Man in 1974 and this gun came with it. I've always liked them since.

3:50 there is a cut down m1 or m2 carbine, can you guys do a video on this?

Delta force loved the m3 up until about the 80s, for room clearing because of it low fire rate made it easily controllable and because it wouldnt over penetrate walls, very critical in hostage rescue or HVT live recovery

epik gun

While the Thompson was heavy and expensive, it was the modifications done to it for WW2 than really made it worse because by lowering the rate of fire it made it much harder to control. In full auto firing, a high rate and a low rate are the sweet spots for controllability But somewhere in between those 2 spots is where controllability becomes an issue. The original Thompson with it's 700 to 800 rpm was controllable on full auto because the high rate of fire was akin to aiming a high pressure hose with a steady stream. The WW2 modification to reduce rate of fire to about 600 made the gun jumpy. Had they lower it even more to about 450 to 500, it would had been better.

The 1911 wss the longest serving US Military firearm. Is the M3 the second longest serving?

History buffs who’ve never fired automatic weapon think the Thompson is an excellent weapon and the grease gun a cheap replacement. History buffs with trigger time on smgs know that M3 is a fantastic weapon that is better then the Thompson by most metrics and is one of the finest small arms of ww2. A marvelous little weapon with no muzzle climb and that is surprisingly ergonomic (relative to it being an angry pipe smg) my only complaint with it are its sights, but otherwise if I was room clearing in France, facing a wave attack at point blank range in Korea or in a denser jungle with sub 150 yard engagements, I can think of few weapons I’d rather have had at the time. It’s a wonderfully crude little weapon!

How many rounds went through them on an average before the spring broke?

didnt make enough money for the beltway parasites lol. first time i held one it was carried by a japanese gsdf tanker in 1983 when we went over there after the russians shot down that korean 747. steve mcqueen. three mags taped in twos.

I like 45 bore i hve this old gun

you forgot the M2

Each tank M48 crews and M 50A1 Ontos crew had M3A1 issued per vhicle, the short coming was the #$#&#$ magazine springs, you had to holes the gun upside_down too keep it feeding rounds!!!

Is there any way I can buy one of these?

Cheap, easy to produce, loose clearances for field use.

And now our forces are wetting thier toes with the APC9k =)

Who's the guy in the video?

Like to have one

okeh

That gun is such a POS

Ugliest stupidest looking gun eever made..
