Making the Beretta 92 Trigger Better – Simple Upgrades

Those who have served and carried an M9 often pick up the weapon outside of the service. Like many of my brethren, I am one of those who did perhaps for the nostalgia or familiarity with the weapon. Frankly, I like the M9, slide mounted safety be danged.

But, one is not limited to keeping their M9 factory-new. With the platform being over 25 years old, various upgrades exist that make the weapon better for self-defense. Even recently, Wilson Combat has released new products and full special edition of the handgun.  Those primary upgrades being a different trigger and hammer springs.

While Beretta (sadly) does not make the 92″D” (double action only) version any more, its legacy lives on in the form of the “D” hammer spring. The spring (typically rated around 18 pounds) combined with a new trigger spring, can go a long way to reducing the trigger pull of the M9. Double action drops from above 10 lbs to around 8 lbs, and the single action is noticeably lighter typically around 4 lbs. The Yankee Marshall shows the difference in a factory gun.

Combatting trigger spring breakage is Wolff Gunsprings, with their Wolff Trigger Conversion Unit, which changes the trigger spring into a coiled unit. It has a more stable stacking ratio, reducing the total pull, especially on the double-action pull.

For those wanting to get a bit more advanced, Wilson Combat has released a new trigger bar as part of their Ultimate Action Tune Kit. The bar reduce over-travel through the use of a boss on the bar. It requires minor gunsmithing to set the boss protrusion, but those with some time and a file will find it easy. While I have not tried one personally, one is on the way to see what can be done!

Bottom line, the Beretta 92 series does not need to stay stock. Many improvements have been released in the last decades and even the last few years to keep the platform going strong.

    When this article popped up, my first thought was that TYM recently did a video on upgrading his 92 trigger. Still needs moar decocker or he won’t carry it, though.

        Not that there’s anything wrong with that!;-)

        Now we’re not here to judge…

  • The D Spring is the #1 Upgrade. That one thing right there makes a huge difference, it’s easy to install, and fast… and it’s only a few bucks. If you have a 92 – Do it.
    Everything else will smooth up with actual use just fine.

    Nathan S,

    You mentioned that you have one of Wilson Combats Ultimate action tune kits on order, and intended to install the contained trigger bar into your Beretta pistol. I was wondering if you could document or possibly film the steps you go through when you begin filing down the transfer bar surfaces. I recently purchased the kit myself for my daily carry, but was discouraged when for the life of me I could not find any suitable guides showing EXACTLY which surface needed what attention. In addition to the lack luster instructions provided, I found multiple stories of people who had purchased the same kit and had improperly filed the transfer bar, causing them to ruin the part. I would be GREATLY appreciative if you could go into some detail regarding your install.

      A file is the wrong tool — a file is for reshaping by removing visible amounts of materials. What you should be using is a polishing stone. Then polish any and all contact surfaces. You can polish either the WC or OEM trigger bar to smooth the trigger action.

      Although you can just wait for break in thru extensive use, you can also polish many of the moving surfaces in the 92 trigger and hammer areas to significantly improve the action. Mostly takes patience.

    I wish I could get rid of all the D springs we have in our armory but unfortunately Uncle Sam doesn’t like to give back what the tax payers already paid for.

    Hello all. Long-time reader on TFB, but this is my first post/comment.

    I can be the first to say that the Beretta 92 upgrades sold by Wilson Combat are top-notch.
    I ordered and installed their low-profile safety lever, steel trigger, steel guide rod, G10 ultra-slim grips, and extractor spring, trigger return spring, and recoil spring, all chrome silicon.

    The feel of the pistol is much better than stock. The steel trigger improves the single action pull immensely. And the fluted steel guide rod inspires more confidence than the stock polymer one. If anyone is on the fence about Wilson’s parts, don’t be!

    A word of warning for the wolff trigger replacement mechanism. For at least the piece I got, there was an imperfection in part of the mechanism. The plunger bar which the spring wraps around, what holds it in place is a crimp on the non spring end. Sometimes this crimp is imperfect and if the plunger bar is rotated around in just the right way the crimp catches on the side of the housing. This will -dramatically- increase your trigger pull weight. I didn’t figure it out until I read up on other people’s experience with this. After this happened several times at the range, I got rid of the wolff trigger spring and replaced with back with the stock trigger spring.

      I just use Wilson’s chrome silicon spring. It’s not perfect, but I’m more confident that it won’t just snap on me mid-range session.

  • Matt

    Point of contention, the Wolff TCU is really not helpful for trigger pull. Since it’s just not that hard to swap the factory spring out if it breaks, I’d say just stick with the factory trigger return spring.

    Trimming the D spring is cheap way of lightening the trigger pull a few pounds. Just be careful not to trim too much because you’ll have light primer strikes.

    • Steve_7

      Trimming springs is usually not a good idea, I find it works better if you weaken the spring slightly. But the spring on a drill bit, spin it and then remove some metal using a sharpening stone or similar. Keeps the same OAL.
