    Hey Guy's, I was wondering what the trigger pull be on a trap gun should be and if there is anyone adjusting triggers on the browning Cynergy? Thanks Brett

    I couldn't find a gunsmith that would work on mine.
    Browning wouldn't touch it either. Trigger pull was about six
    pounds and creepy. Ended up getting rid of it.

    I am posting what I downloaded off of TS.com a little over 2 years ago regarding Cynergy trigger adjustments. If you take your time and read the instructions it is real easy. I did my 20 ga field gun and it has an acceptable trigger pull now.

    Reducing Trigger Pull on Browning Cnyergy
    I have been getting many emails regarding this artical so I thought I'd re-post it.
    If you do the following procedure you will do it at your own risk. You may void your warranty. Browning Arms does not want you doing this. If you are not comfortable performing this kind of work, or don’’t understand these instructions DO NOT PROCEED. Take it to a gunsmith.
    You will need some tools. The tools needed are a dial caliper, small assortment of brass drifts, smooth face 6-8”” file, Med and fine indiana stone and a 4 or 6 oz ball peen hammer. All measurements are in inches.
    Adjusting the trigger pull on a Browning Cynergy is not difficult if you take your time and follow these instructions. The Cynergy, that I purchased, came with a trigger pull of 4.75 lbs and lots of ““trigger creep””. For me that is way too heavy. I prefer a 3 lb pull.
    Don’t bother calling Browning for help. They won’’t tell you anything. I called 10 gun shops around the country, some were Browning authorized repair facilities, and no one seemed to know or wouldn’’t tell me how to reduce trigger pull. One gunsmith said he files the sears down, however the sears don't last long. That is not the way to reduce the trigger pull.
    Prior to starting check the current trigger pull. Check each trigger at least 3 times. Write down your findings. Both triggers should be the same. If not no problem you will be able to adjust later. To start with remove the recoil pad and butt stock. As of this writing, there seems to be 3 configurations of recoil pads. My recoil pad had the traditional #2 phillips head screws top and bottom. Prior to inserting the screwdriver put a little 3 in one oil on the tip and shank of the screwdriver. This will prevent tearing the recoil pad. Once the pad is removed remove the butt stock. My Cynergy came with a long allen wrench to remove the socket head screw located in the butt. Make sure the break open tang is in the closed position. This will save your stock upon removal of the butt stock.
    Once the butt stock is removed take a good look at the internal mechanism. You will notice it is different than most trigger mechanisms. Pay close attention to where and how the sear engages the firing spring. This will be the spring with the castle nuts and a cotter pin. First you want to start by removing the sears. The sears are held in place by a pin with an e-clip on the right side of the receiver. The pin goes through both sears. On the opposite side of the e-clip is a head to hold the pin in place. Remove the e-clip. Be careful. This little clip will shoot across the room when removing it. Try and hold your hand over the side the clip is coming off to prevent loosing it.
    Once the clip is removed use a brass punch and drive the pin out. The pin is knurled under the head side to keep it from moving. This will require a little force to drive the pin out. A 4 ounce hammer should work fine. The sears rest against the firing pin, which are spring loaded. When you drive the pin out the brass driver will hold the sears in place. Once the pin is removed the sears will be resting on the brass driving punch. Slowly remove the brass driver. Now the sears are free to come out with a little jiggle. I will remove the one on the left side first. Mark-it and then remove the other sear and mark it so you know which side they came out of.
    Once the sears are out now is a good time to start working on them. Start with the first one you removed. If you have excessive trigger creep, as mine did, now is the time to improve it . Using a dial caliper take a measurement from the back side of the sear, on the flat, to the tip of the sear. It should measure .035 +/-. Mine was .044. using a ““smooth”” file remove the excess from the sear. Keep the sear face square to the file. Only make 2 passes and then re-check the thickness and squareness to the file.
    If you get a little off here it can be corrected. Make sure where you filed is even across the face of the sear. If not adjust your file cut to square it up. With 2 passes on the file you should have removed about .001-.002 depending on the condition of your file and amount of pressure you applied. Always keep your file clean of chips. If you removed .002 on your first 2 file cuts and everything is pretty square continue filing.
    You may want to make 4 passes then re-check measurements. Keep filing until you reach a thickness of .026. When you reach .026 stop filing and start honing with a stone. I uses a course stone to bring sear down to .025. When I have reached .025 I then hone with a medium stone. (medium stone being 220 grit). I medium stone until I reach .024. That is where I stop. I could have gone a little further maybe down to .020.
    Next I medium stone the part of the sear that rests against the ball end of the firing pin. Holding the sear square to the medium stone hone until the face is slick and shinny. I’’m not sure this part is necessary , but it can’’t hurt. The 1st sear is now finished. Repeat this process on the other sear. Remember take your time. Don’’t get in a hurry. If in doubt re assemble and test fire or at least dry fire with a snap-cap. If you reassemble and test with a trigger pull gauge you will notice your trigger pull has been reduced by approximately ½ lb. To Reduce the Pull of the Trigger
    Remove the pin that holds the firing pins. This pin is located below in about the middle of the receiver, just forward of the upper part of the trigger sears. The one pin holds both sears. Again you want to drive the pin out with a brass drift. The firing pins are spring loaded. As you drive the pin out apply pressure on the ball end, of the firing pin. The ball rests against the sears. This will keep the firing pin from shooting across the room and keep the holding pin from galling the firing pin while removing. Take note on how the firing pins are installed. The firing pins have a relief cut in where the pin goes through. This relief holds the firing pins in place. Once the pin is out the firing pins should slide right out. With the firing pins out you may need to place the receiver in an up right position to remove the firing pin springs. Measure the springs with a dial caliper for length. You will not get an accurate measurement but close enough. Close the calipers until they just touch the springs. Try not to compress the spring, however, you will compress the spring a little maybe .001 - .005. I doubt this slight compression will make a difference in trigger pull.
    I cut my springs off to a length of .840. This gave me a 3 lb trigger pull. Over time this will lighten up a bit. Maybe to a point that I will need to replace the springs to maintain a 3 lb trigger pull. I would suggest cutting the springs to .940 length. Then completely reassemble and test.
    I cut both springs to the same length. By making your first cut on the springs at .940 +/- and reassembling you will be able to tell is one spring needs to be cut a little shorter to match the other spring. Some prefer a harder trigger pull on the second shot. It’’s up to you and your preference. My guess is a .940 spring length will equal to a 3 ½ lb trigger pull.
    If you cut the springs a little short, a quick fix would be to shim with small washers, or turn some shims down on a lathe to thickness to obtain the desired trigger pull.
    When reinstalling the firing pins make sure to pay attention to the slot in the firing pin that the holding pin goes through. You will need to compress the firing pins to allow the holding pin to drive back in. Failure to do this will result in damage to the firing pins.
    As stated above my Cynergy is now set to a 3 lb trigger pull. I left the slightest amount of trigger creep for safety and wear reasons.
    On May 24, 2009 I tested the trigger modifications. I am happy to report all is fine. The lighter trigger pull feels a lot better to me.
    Update: It has been several months since I have performed this and all is well. No problems. The trigger pull is still at 3 pounds.

    Interesting statement made about Browning not wanting to work on the trigger. My Cynergy Classic Trap had a hard trigger on the bottom barrel (9 lbs). I sent it back to Browning with a written explanation and what I wanted for the trigger pulls (3.25 lbs). Although they kept it for 5 months, when it came back they had changed out everything on both triggers set the bottom barrel trigger to 3.3 and the top to 3.25. As many Cynergy owners know the first few thousand were rushed to the market and thrown together very poorly. Many had trigger problems, I believe mine was part of this group. Although Browning will never admit it; I think they feel obligated to those that step up and demand they be fixed. I must add that I asked them to fix it under warranty against defects, they said no but only charged me $165.00 including shipping from Missouri. That's my story and I'm sticking to it.

    I wrote the article regarding the browning trigger pull. If you have any questions email me and I will help you. Email me before you start. It's fairly easy and all the steps don't have to be performed.
