Here is a picture i found when moving threads the other day, showing the relocation of the 52C trigger pivot pin. I have not done this with a Winchester trigger but i tried the mod with my Kimber 82G. The Kimber pull went front 2 pounds to 6oz on my Lyman digital guage... but i did get a bit of creep with the Kimber.
TAKE IT FOR WHAT IT IS WORTH.... joe:)

Canjar

Good evening, If your trigger is an LP-52, I have the paper work from Canjar, I just can't lay my hands on it at this moment, but when I do, I'll have to find someone to help me get it on these pages. The LP, has a thin wire that runs top to bottom in that thin groove, on the right side. That wire when pushed upwards, from inside the trigger guard, lowers the sear or, if the trigger is held back, holds the sear down, allowing the bolt to be removed. Is that wire there? I'll effort getting the Canjar instructions put into a form that I can post here. Cheers Charles

Joe,

Its not my pic. I was only making a comment on pin placement.
I think Karl has been at it for a very long time and I would sure credit him. The basic idea can be used on some other triggers. I was surprised with the "B" trigger conversion.
Its hard to adjust the introduced creep out. This is a four lever trigger and sear engagement is two levers away and once adjusted properly no adjustment to it will effect the trigger movement. The gain in movement is all in the pin placement. When the trigger was designed it basically had no movement (Micro-Motion) and was for the 3 pound rule. To alter the pin placement will alter *** but you give up slight creep because now you must move it a slightly longer amount to get it to do the same thing.

In a simple two lever trigger creep is easily adjusted out with sear engagement (Rem 40X trigger) multi levers are a horse of another color.

In an original Kenyon trigger (Not a modified Win) its of 3 lever design with the break engagement surface on the trigger lever itself and the middle lever and is adjustable.

Actually all the Canjars for the 52-C have that release wire loop. No need to remove action from stock if its there. As Charles mentioned it is a wire loop hanging down inside the trigger guard up close to the stock in front of the trigger. If its not there one will have to be made.

trigger

Yes, the factory did make a change to the design of what Winchester calls the trigger lever. Its the long middle lever through the middle of the housing and not the lever on the trigger as the name implies.
Originally it was pivot pinned up where the trigger finger makes contact.
Winchester discontinued that pivot point and dropped a leg down in front of the trigger proper and pinned the pivot at the lower end of the trigger housing.
This change gave the formally straight shaped lever a somewhat "L" shape. There are no drawing of the later design that I'm aware of.
This change can be noted from a pic of the outside and placement of the pin. The trigger above is a "C" style.

Here are some pics that might help show the difference between the C & D trigger assemblies. I have marked the housings with either a C or D&E to differentiate the 2 units. Look closely and you will see the area circled in silver that show the different pivot point between the revised levers. The "X" shows where it is missing on the C model. Also note a couple of other changes, the slot at the front of housing is a different size for the different triggers. It was widened on the D revision. I have marked the slot with arrows on each side. Last change is the engagement screw design which was changed at the onset of the D model as well. It went from a spring loaded (anti vibration) assembly to a simple screw. Apparently the performance of the former it not measure up to its cost.

I came to this thread looking for disassembly and reassembly tips and was surprised to see that the trigger in my repro-52 is different from everything else here. My rifle is a Winchester and the stock does NOT have the Monte Carlo hump (which I think is rather unattractive), so I guess it is a 52B. Is that correct? The serial on my rifle is 10NR802XXX, if that is any help to anyone.

The "ISU" trigger was just a Kenyon with an adjustable trigger shoe which moved fore and aft, and had a straight post in lieu of the curved non-adjustable shoe as was installed on all the conventional Kenyon triggers at that time. Later Karl would make his trigger in either configuration requested by customer. Kenyon triggers were an option on the 52D & E model Internationals. He also sold hundreds of the same trigger on an aftermarket basis. All of his triggers which he manufactured were stamped "Kenyon" on the side plate of the housing. He also modified hundreds of factory 52 Micromotion triggers to lower the pull wt. These were typically not marked, but can be identified by the extra pivot holes he put in the them for the lever pivots. Many other gunsmiths still perform the same modification.
If you would post a picture of your triggers, I'm sure we can I.D. them. If you cannot post, just email a picture direct to me at seewinr@aol.com, and I will try to help you out.

RiverRider,
As I understand it, the 52 repro's made in Japan are basically a copy of the Winchester 52C MicroMotion triggers but are not an exact duplicate. The first generation Japanese M52 repro's were the "Browning M52s". Their stock, too, was modeled after the Winchester 52C, with the Monte Carlo.
The second & third generation Japanese M52 repro's were sold as "Winchester M52Bs"; their stock was modeled after the Winchester 52B though they use the same MicroMotion-based action.

Trigger thread

Today I just picked up an early 52, 1928 build date. Any info on the triggers on them? It feels like a crisp, but 5 LB pull. I have not had time to look at it yet. I would like to get the pull down.

I like Joe did the trigger pivot pin mod on my Kimber, it is about 2 oz, but now has creep.

My C & D feels great, I would like to redo the trigger on this early 52 also.

I have one not listed here

I have a Pre-A 52 with a trigger I don't see here. The engraving is almost illegible. Reads "Ha** Arms - Pat App For - Cleveland." The trigger guard has a small cut out in the center to allow the trigger to be pulled down/forward to release the bolt.

My 52 is SN 35510. Marksman stock. No sights, but with and extremely well-made custom scope mount base that does not require D&T of the receiver. Action is steel/pillar bedded with the original factory barrel set back, match (jam) chamber cut, and barrel recrowned. It is in immaculate condition.

I'm working on photos. I'd LOVE some input.
