Improve DA pull on Beretta 92FS

Thanks for that trigger job link.

I thought the general rule of thumb is to not clip coils, but I guess there are exceptions.

I've had a hard time clipping coils myself. Perhaps I don't have the correct tool. Suggestions?

If I'm going to have him replace the mainspring I might as well, according to your suggestion, have him clip the coils as well as part of the process.

So, your advise is to go with the Beretta D and not the Wolff, and this is because you have personal experience with the Beretta D and not the Wolff 16# hammer spring?

Prompt reply appreciated!

I usually use a jeweller's file for that.

Exactly. When working up these mods, you need to know the free height as well as spring rate. It's also better if someone has gone and boogered one up to find the limit. I've done both with the D spring, but not the Wolff. :o
 
Thank you very kindly.

If I decide to go ahead with this, I have the double-whammy - grip screw/bushing problem with the grip, and the actual replacement of the mainspring.

If I do go forward, this will be left to my gunsmith.

Where can I get the actual Beretta spring?

I have this guy's url:

Do you know of others?

Thanks,
 
Marrying the trigger is also called boosting..
you are essentially removing any type of burrs on the sear and the hammer hooks. as long as the hammer hooks are excessively deep..it does a good job in single action..

this will do nothing for the double action pull..as the hammer will not ride on the sear for its release..

to lighten or smooth out the DA pull..the lighter D spring is the easiest way to go.
more can be done..but entail polishing of the internals, trigger, trigger bar, hammer etc. also you can try modifying hammer springs..lengths and widths..

but some knowledge of the internal workings of your gun is a must.

not unheard of to get a completely reliable DA pull 6# or under 4.5 with specific primers.
 
brent,
No biggie. The D spring needs to be ordered directly from Beretta.Your gunsmith should be able to get it for you.
Or you could order it from BerettaUSA. Part # UD99001.
 
The link brent posted is an excellent site and you should book mark it. I have done lots of business with the guy on the site and he is top notch.

Also, the Wolff spring is ok and will get you by (I keep one in my spare parts kit), but go with a 'd' spring.

Just a reminder:
The 'poorboy' trigger job may be something worth doing in and of itself, but the first point won't address the DA pull of a Beretta and the second part is impossible to employ on a Beretta. And even if it were it wouldn't be worth doing.

The DA trigger on the Beretta is like trying to squeeze a bag full of gravel. :o The biggest offenders are
#1 the mainspring
#2 friction throughout the innards (trigger bar, sear axis, hammer trunnion, hammer strut)
#3 the sear spring
#4 the pin block return spring

A decent 92/96 trigger job will address the SA pull in the course of remedying the DA pull.

From Olhasso website:

"HS-001- 92/96 "D" hammer spring -- This is Beretta Part number C99001 and is a true D spring. The part that BUSA is currently selling as a D spring is indeed part number C90047 which is in fact a standard F model spring".

Any comments?
 
brent,
If BUSA is stocking incorrect springs, this is the first I'm hearing of it.
You can verify a D spring by length.
Free height of a D spring is 2.4", whereas an F spring is 2.67".
HTHs!
 
This is just another PITA, which makes three PITA's.

One is grip screw/bushing problem with the newer Taurii PT92, second is replacing the hammer spring on that gun (with its internal lock and other idiosyncracies), and now this... :barf: :D
 
brent,
Doesn't really matter where you get your D spring so long as it's a D spring. Go ahead and get one from Olhasso, just measure it before you clip it.
