I recentley picked up a new Beretta M9 and wanted to swap out the mainspring in order to lighten the trigger pulls.

Should I go with the "D" spring or a 1911 spring, and if the 1911 then what #?

Thanks.

Go with the D spring (18#).You can pick one up, and spare parts, from Wolff HERE. Remember, your wanting the 18#. I'd advise against using the 1911 spring; there have been instances that point to increased frame/hammer assembly wear. FWIW

Always always always always go with the factory spring over one that "matches"!

A 92 is too good of a gun to do this to & you may very well need a reliable ignition that a factory spring is much much better capable of delivering, IMO.

the factory weight spring is in there for a reason-I saw a bunch of my friends change mainsprings in 92's and yes the trigger pull is lighter but they often fail to go bang as a result- the answer to a heavy trigger is to shoot 1000 rounds with the gun and get used to it

The D spring (18lbs.) is a factory spring for Beretta. It comes in all their D models (DA only pistols) so should work 100%. There should be no misfires unless using ultrahard primers. Now with 16lbs. springs you may start getting light hits.

What about 17lb springs?

Just thought I should add what I just found. There is some discussion at Beretta.net and apparently the actual factory "D" spring is a 16LB one and not 18LB.

Take it for what its worth...

I've put Beretta Factory "D" springs inside my 92FS and my Cougar 8000F. I've had no issues with either. Both had noticably reduced trigger weights. My only complaint is that the DA trigger pulls are very long. Oh well, at least it isn't as heavy!

I'd keep the factory springs.

Yeah, that's my exprience. No noticable difference with the 18 lbs. Wolf. From what I've read that was the weight to go with but it seems that's not so. Some suggest the D spring is actually somewhere in between the 16 and 18 lbs Wolfs, being closer to the 16 lbs. I'm going to just get a factory D spring.
