M44 US doesn't stay cocked



Log in to see fewer ads
I have several M44's that I bought from CMP long ago as incomplete rifles and I'm now taking a look at them. I have one that doesn't stay on cock as I close the bolt. Does that indicate I need a new trigger?

On another one, the bolt slides all the way out of the receiver without holding the trigger back. Is that also a trigger issue? There is no spring tension on the trigger when the bolt is closed.and not cocked. This one does stay cocked and will fire.

Sounds like you are missing the spring and plunger from the trigger. That is the only thing that puts pressure on the trigger to reset it, I canít remember, but I donít recall the 44 trainer having the secondary adjustment.

Look a few post down, John has some pictures of the trigger assembly.

Look at this exploded view https://www.rimfirecentral.com/forum....php?p=6069441. Scroll down to 44US> Item number R149 and R 150 are what we think you are missing. Hopefully someone has not tried to lighten the trigger pull by removing metal?

Took it apart for a look and I am indeed missing the plunger, the spring seems to still be in the recess but I'll see if Havlin's has both tomorrow, thanks for the quick help guys!

Someone may have tried to lighten the trigger pull or it could have just disappeared when disassembled. It is pretty small! Good luck .

You can make 1 if you have a hand drill, drill press, bench grinder . You need to determine what size the hole is and use a drill bit the same or close to size. Cut off a 1/4 inch section of the shank. Its tough not really hard. make 1 ended domed and the other square. Do not lose the small piece. LOL

General comment for the DIY folks.

If Havlin's do not have the plunger, take the trigger to the hardware store and buy a piece of music wire / piano wire that fits the hole (might be 3/32"). Cut about a 1/4" length, deburr, then lightly round and polish one end (top) and flatten (spring) the other.

I will eventually disassemble my spare trigger to make accurate measurements - something i should have done that the first time around.

A couple of notes:

Have an open work area and magnets.

Music wire and broken drill bits are wonderful materials. I have used music wire for a missing trigger pin, and to make springs. Once you buy a bundle (it's inexpensive), you have a lasting supply.

Keep some 18 - 22 ga copper wire and metal twists from bread loaves, etc. to hold parts together temporarily.

Take pictures, measure parts, take notes.

I use key pins from old home door locks, they are the correct size and are already beveled on one. As already mentioned, a nail will work. Chuck it up in a drill and round one end and then cut to length.

Check to see if the trigger is hanging up on the shrunken plastic trigger guard. That occurred on my CMP 44US. A replacement guard from Havlin's fit perfectly and solved the problem.
