Mi Garand Trigger Mech Parts that interchange with M14 Trigger Mech's

Questions on this come up often enough I thought it may be a good idea to start a thread on it. We have to break this down into a few sections.

Parts that directly interchange with no special fitting required.

1. Hammer.
2. Hammer Pin.
3. Trigger Pin.
4. Hammer Spring.
5. Hammer Spring Housing.
6. LATE WWII or later Hammer Spring Plunger that does not have the early Garand "ears" or "wings" on the sides.
7. Safety. Now the early Garand "flat top" safety will directly interchange and work, but they crack easier than the Mid WWII ones that are curved on the tops. So I suggest you leave the "flat topped/early" Safeties to collectors.
8. Trigger Assembly. Of course these don't have the wider sear that M14 trigger assemblies have, but if you don't have a legal FA capable M14, you don't need or even want the wider M14 sear. We cut/grind down ALL M14 sears to the width of M1 Garand sears for NM rifles. I do it on ALL M14 trigger assemblies I install in Semi Auto only commercial M14 rifles as well.

Part/s that fit after modifying the M14 trigger housing.

1. Early Garand Hammer Spring Plunger WITH the "ears" or "wings" on the side. I PREFER to use these in NM M14's and even have one in my "Walter Mitty" or SHTF rifle. HOWEVER, you have to cut/grind a half circle clearance cut on the right side of the M14 trigger housing so the ear on that side does not hit the M14 trigger housing.

I found that out over 25 years ago when I wanted to put an early Garand hammer spring plunger WITH ears on it in a Match rifle. The "ears" keep the hammer spring plunger nose more centered in the notch of hammer and it can't move side to side as much. That means the pressure is more consistant and gives you a more consistant trigger pull.

Now we almost never put them in the NM M14 rifles we built for the Marine Corps BUT the reason was they were no longer in the supply system (we thought) and no one knew about them. I "took a chance" some MIGHT still be in the Supply System under the older M1 Garand NSN, when I was stationed in California in the late 80's. I ordered 10 of them and got 6 with "ears," so I put them in our NM M14's after modifying the housings. Not long afterwards enough parts came back from Korea on the civilian market, that I went out and bought enough for the rest of our NM M14's.

Funny thing was I have actually seen these plungers WITH ears and the M14 trigger housings modified for them in REAL M14's that Law Enforcement Agencies have received from Homeland Security.

Parts that DO NOT interchange between M1 and M14 trigger mechs.
1. Trigger Housings.
2. Trigger guards.
3. Safety spring or Clip Ejector on the Garand.
4. You SHOULD NEVER put an UNMODIFIED M14 trigger assembly into a Garand Trigger mechanism even though it will go in without any fitting. Garand stocks do not have the little vertical clearance groove just ahead of the rear bedding surface for the rear end of the trigger housing. That groove is meant so the wider M14 sear does not rub in the stock and cause the rifle to double, triple or go full auto.

Of course you CAN cut that vertical clearance groove in an M1 Garand stock, identical to the one on an M14 stock, but WHY do it? Just cut/grind the wider M14 sear down to M1 Sear width and then you CAN use the M14 trigger assembly in an M1 trigger mechanism, should you wish to do it.

M1 triggers?

Gus, As you know the M1 triggers are a little different than the M14 triggers in that they offer a more complete housing for the pin., this is not always true but most of the M1 triggers have a complete hole. i prefer the M1 trigger for this reason it adds a more stable platform than the partial pin passage in the M14 triggers.

What are your thoughts on this?

Also, I need a new M1 recoil spring, I read you have some for sale, please supply details...

Best regards,,, Art

Thanks from Bamban

Great point about the M1 trigger assemblies that have metal completely surrounding the hole for the trigger pin. That helps especially a NM trigger job last longer and I prefer to use them for that purpose. Late M1 and all M14 trigger assemblies don't have metal all around the hole for the trigger pin and they have a tendency to "chisel into" the trigger pin and wear it out faster.

I'm out of stock on Garand Op Rod springs right now and have to order some in the next couple weeks along with 79 other things I'm trying to remember. Grin. I suggest you order it from where I buy them at Orion 7 at the link below:

Now I have heard several arguments over this one.

Garand Clip Ejector Spring

I had someone tell me they cut off the part that ejects the M1 clip to make M14 safety springs. Mostly with ones that won't eject enblocs any longer.

Is this a good idea?

Please understand I've never done that because both on Active Duty we got the correct parts and for many years real M14 safety springs were cheap on the open market that I laid a good stock in for private use. Also, the M14 safety springs rarely wear out or break.

It MIGHT work, but it may not. I really don't know. Personally, I would put the correct parts in each trigger housing.

The original ones do a lot.





It used to also be fashionable to break the ends of the safety off so that you could safe the rifle uncocked. I don't recommend doing that however.

Thanks from Diablo Gato

Is that from trying to force it with the hammer decocked?

I asked because I think I read somewhere that the Spring field armory did just that when designing the M14 rifle in the various T versions. And that they literally took the M1 clip drawing and erased the clip ejector end to make the M14 part. I know I have seen someone do it to replace a broken SAI part.

When you put the garand part and the M14 part next to each other they are exactly the same except for the M1 clip ejector.

It's certainly easier then filing the auto tabs off M14 triggers.

It should also be noted that the M1 Garand Winter Safety is interchangeable.

GREAT PICTURES and thanks for adding them.

These flat top safeties cracked and broke there so often that Springfield changed to the round top safeties in Mid WWII, but Winchester was allowed to make the earlier/weaker ones throughout WWII production. After WWII, all new safeties made by the SA, IHC and HRA HAD to be the round top safeties as well as all contractor made safeties made as replacement parts and that included through the M14 production.

I did not see a lot of cracked or broken M1 or M14 round top safeties on active duty, BUT these rifles were originally required to go through 3rd Echelon/Ordnance Gage Inspections on an annual basis. So they could have been replaced a year or two before I inspected the rifles. We did not see many cracked or broken round topped safeties on NM rifles and we kept a gun book detailing what maintenance was done on them for years.

I have seen more cracked or broken round topped safeties on the Garands that came back from Korea, BUT we have to remember the Koreans were wise enough to sell us their WORST condition Garands FIRST. Many of those rifles were used in WWII and inspected/repaired/rebuilt before they went to Korea for the Korean War. Many of those Garands had seen more use than any other Garand most of us are ever likely to see and the preventative and corrective maintenance does not seem to have been as important to them.

FUNNY thing is I've seen a VERY SMALL number of safeties that were cracked or even broken off on DCM Garands and Homeland Security M14's. SOME of these were actually parkerized OVER the cracks or broken tip areas. That's a HUMOUNGOUS OOOOPPPPPSSSSS on the part of the refinishers and final Inspectors, but like any human endeavor, nobody is perfect.
