Hold on guy's .... I'm not suggesting that any trigger alteration is superior to a full blown professional trigger replacement.
It's not even close. I am saying, that with a little creativity you can make considerable improvement's to any existing trigger design.
My old Springfield 1922 M2 or a new Bergara B14R. They are all simple mechanisms that involve springs and levers.
This actually started on another thread.... It was suggested to me that I could ad a #4-40 set screw to the B14R trigger to limit it's sear
engagement and that was the perfect solution. I tried to politely say that they were missing the boat on a lot of opportunities and
and I was looking to capitalize on some really tricked out options to enhance the Bergara 700 style trigger. One guy came out and said the #4-40 was perfect !! I tried to explain to him that I saw a plethora of opportunities beyond a heavy, short sear engagement.
I also mentioned that the set screw they use should have a oval tip and a nylon locking element. There is a distance between the trigger
and the housing and a short set screw could simply fall inside the trigger unit. That would mean grinding the seven rivets off to clear the problem.
My first attempt at altering the trigger weight was to ad a 6-32 spring plunger. It pushes the upper portion of the trigger in a clockwise
direction against the factory spring. That does two things. First, the body of the plunger limits the sear engagement just like a set screw does. Second, it's spring loaded nose will counter balance against the factory torsion spring. So according to the factory published weights, the trigger spring exerts a value of 3 pounds and three ounces, a total of 51 ounces. My added plunger exerts a force of 40 ounces in a direction opposite of the factory spring. So the net result is 11 ounces that your finger needs to over come. That neglects friction and blah, blah, blah..... and blah!
I have skipped a lot of details, ratios and coefficients of friction and dumbed it down to the point of being inaccurate simply to convey a concept. The bottom line today, with my first attempt, without grinding the 7 rivets off to get inside the trigger, my
pull weight is 11 ounces. Oddly, the trigger feels like my six once Annie but it still measures 11 ounces on the scale.
That makes it 21.5% of the factory pull weight. To me, that's a good start and it's a fun puzzle for me to work on.
I will refine it more tomorrow just because I can. I feel compelled to find it's limits prior to cracking her open.
I want to avoid that because the average person wont want to do that. What I have done thus far has been: Easy Peasy!
If you had the 6-32 tap the entire alteration would cost you $6.00 plus shipping from McMaster-Carr.
One of my more bizarre ideas is to incorporate magnets to do my dirty work !!
To me, this is simply another exercise in mental gymnastics and I do it simply as a challenge and for the fun of it.
I pass the information on to the SH group for people that lack the cash to burn. On that note... If you haven't paid $50.00 for
your gun to be lot tested, your wasting your time. My Vudoo will shoot .34" ctc groups with good ammo and .875" ctc groups
with the wrong Center X ammo.
Is the trigger worth replacing??? I will shoot it and decide tomorrow. Personally, I doubt my B14R would be my first choice for BR
matches anyway. My Annie 54 Super Match would be a much better choice and she is a stock gun. I feel like the Bergara is a very nice
rifle given it's price point of $950.00 It's unlikely I will change much of her factory configuration. I'm thinking she will remain my
Factory Class gun.
As a side bar.... I just bought a Springfield 1922 M2. Someone parkerized the devil out of every component to the point of it being monochromatic. . I was able to find a perfect arsenal refurb and duplicate it's appearance. She looks great now!! I also found that
their are hundreds of M1 magazines but none for the M2 and they are not interchangeable. I bought a M1 magazine with hopes that I
could make it work with some small alterations.
Upon receipt of the M1 magazine bought on evil bay, I have compared it to my M2 magazine and I fail to see why it wont work in my gun.
On 10/28/2021, I will put here back together and confirm that the new M1 mag will work in my M2 rifle. My gun has a SN of 2259B. The "B" indicates that all of the arsenal modifications and upgrades have been done.
Hopefully I will be able to let you know that the mag works and you may not need to spend $175.00 on a M2 magazine if and when they become available.
