Beretta 92FS - What is a "D" spring?

I keep hearing about a "D" spring what is it? what does it do? How will it affect the trigger pull? Is it worth it? Any info is greatly appreciated. Thanks

The 'D' Spring you are hearing about is the mainspring from the D model. It is a DAO (double action only) model. I hear that some people are using this spring in the DA/SA models to lighten the trigger pull. I like the trigger on my FS Compact just fine. Plus they are kind of a PITA to change, so I would just leave it alone...

They are actually easy to change. It's a five minute job tops, and the majority of the time is probably spent removing and replacing the grips.

The D spring will take about 4 lbs or so off the trigger pull in double action.

the spring costs only $4 and literaly takes few minuted to change; trust me it's very easy and well worth it.

instant trigger job!

How will it affect the trigger pull on the single action mode? I hardly use the double action mode. Thanks

It's a slighter reduction on the single action.about 1-2lbs maybe.

The spring is in the handle. Remove the grips, use a punch to push out a pin, pull out the punch, the lanyard loop hole pops out *under pressure* to reveal the spring. The spring is over a metal rod. Take out the spring, slide the new D spring over the rod, put the lanyard loop back in, line up the holes, push the lanyard loop down against a table or something sturdy until it compresses the D spring enough for you to push the pin back in. Put the grips back on. Done.

Here is what I used to help me do mine. Wonderful diagrams:

I know nothing about guns, probably use the wrong terminology, but it was easy to do. This was on a 92FS.

When you order the spring make sure to get one that is #18. There are other varieties of springs for sale that go lower. Stock spring is #20.

I read this somewhere in this forum, it's a direct cut n paste from a word document:
---------------------------------------
Statistics of three springs:

92FS--Trigger pull factory spring = DA 11.8lb
SA = 5.55lb

Trigger pull with "D" spring DA = 8.10lb
SA = 4.00lb

Trigger pull with "Comp" spring DA =8.0
SA = 3.8
----------------------------------------

I've heard people say not to use the competition springs for defense guns.

yes, the comp spring may not have the force to detonate all primers reliably IIRC only the federal primers should be used.

david olhasso sells them; do a search on a google his site will come up

Yeah Dave has them and the extended mag release "Inox" style. These are two must have items for a beretta 92 or 96. Midway also sells a wolf D spring as well, same quality and works just as well. This is the first thing I replaced on my new 92FS. My 96 Brigadier already came with a great trigger pull and I had a custom smith do a lot of competition style work on it which included the competition style spring. When using a comp spring I have found that Winchester, Federal and Remington (and a few select Hornady loads) will fire. The CCI and assorted others will not work. If you hand load this is not a problem, but if this is your carry pistol and you dont reload I would just stick with a D spring.
