In this case "WC" means "Wilson Combat," not "water closet."

I bought a Beretta Brigadier used maybe 15 years ago. For those who don't know, the Brigadier model is for those who find the regular M9/92FS to be just too delicate and gossamer for them. The Brigadier has a heavy slude, metal trigger, and a steel guide rod. Also, the sights are dovetailed.

Mine came with AWB-era 10-round magazines, so unless the previous owner added them later, the gun was made between 1994 and 2004. I've shot it a lot. I don't know about the previous owner. So, it seemed a bit snappy to me despite the 37 oz. (2.3 lbs., 1060 g) weight. So, I wondered if the recoil spring was wearing out. I also had a chance to compare the trigger pull with that on the CZ 75 P-01, and in comparison, the Beretta trigger just sucked on toast. It was heavy, even in S/A, and there was a lot of slop in the take up.

ORDERING

Sooo, I ordered the "duty" replacement springs kit from WC. The "competition" package said it wasn't good for +P, and I didn't want to stipulate to that ahead of time. So, the kit comes with the following springs:
recoil,
firing pin,
ejector,
hammer (a choice of two),
trigger.

The kit was listed at $25.95. Seems reasonable. In addition to that, I was charged the following:
shipping and handling $11.51 (Really? It costs twelve bucks to put a spring kit in an envelope and to mail it?)
sales and use (6.75%) $1.76 (Is that a tax?)
shipping (6.75%) $0.77 (Shipping, again? and since when is shipping a percentage of the price?)
tax. $ 2.53 (WTF?! Didn't we already do that?)
So, paraphrasing Bob Barker, the actual retail price was $39.99. It really looks to me like WC just wanted to charge $35 plus postage and tax without saying they were.

INSTALLATION

So, the springs arrived really quickly. I really only needed the recoil and hammer springs, but, like an idiot, I installed them all. The firing pin spring was the most gigantic pain in me *cough!* what now? Anyway, there are so many tiny springs, pins, and plungers in and around that slide-mounted safety. Wow. I'm an only an amateur gunsmith, so it took me a long time. I used the lighter of the two hammer springs.

Before reassembly, I polished all the moving parts with Flintz and a Dremmel buffing wheel. Then I regreased the interior moving parts with Gun Slick, a grease with graphite particles.

Reassembling the gun finished with re-installation of the inexpensive, but very grippy, hard rubber panels. So, Beretta uses reasonably wide screw heads with cartoonishly small Allen key holes, which I managed to round over on one of the screws. I have ordered some Beretta slotted screws. Frankly, I think all machine screws should be slotted, and one should use a hollow-ground screwdriver to install or to remove them.

RANGE TIME

I brought five 15-round Beretta magazines loaded with 115 grain (7.5g) FMJ CCI Blazer, brass casing cartridges. They were completely reliable. As usual, the gun was more accurate than I was. The recoil seemed a lighter than usual, so maybe the the factory spring was worn.

As usual, I shot at 6" (150mm) circular targets at 10 yards (9.144 m). D/A was still pretty stiff, though maybe not as much as before. The S/A felt lighter and generally better. It still had all the take-up slop that it had before. So, yeah, it's definitively an improvement, but the CZ P01 still has a better trigger.

There is some more you can do. Most of what Wilson Combat does to the Beretta 92, was taught to them by Ernest Langdon. Langdon runs Langdon Tech.

Langdon designed a trigger bar for Wilson which dropped the necessary hammer spring strength necessary for ignition by increasing the arc of hammer movement during double action cocking. The stock Beretta hammer spring is 20 pounds. Beretta's weakest hammer spring strength is 16 pounds, the "D" spring. With the increased hammer arc trigger bar, I have gone to as light as 12 pound hammer springs with 100% ignition. This reduction in hammer spring strength drops the double action trigger pull from about 12 pounds to about 7 pounds.

Langdon designed another trigger bar for his own company, which does the above, plus shortens the reset. He also has drop-in parts which give most of the benefit of a trigger job, called a "'Trigger Job in a Bag." I have had Langdon do several trigger jobs, plus dropped in several TJIAB. Magic.
