Today I received a 3.5 lb. reduced power striker spring for my
S & W 9VE Sigma 9mm, which was ordered from Wolf. The package is marked "WARNING FOR COMPETITION USE ONLY MAY REDUCE RELIABILITY". I installed the spring, and noticed a significant inprovement in the trigger pull. I have not yet fired the gun, but will do so tomorrow. Can anyone, who has installed one of the reduced power springs in a Sigma, tell me if they have had a problem with reliability ? Or anyone else with comments. Maby I should just put the original spring back in, and trade it in for a Glock. I wanted a Glock 19 when I bought this gun, but was concerned with the extremely light trigger pull on it, for concealed carry. I have heard of too many accidental shootings because of the Glocks trigger. The trigger on this one is about right, with the reduced spring.
Thanks,

Hi,

I just received my sping as you did. Exactly where does the spring go? The spring that i recieved does not look like anything in the gun. Thanks.
 
G,
You can see if there is going to be a reliability problem by observing the difference in primer strikes from before and after the change. The reliability aspect is going to be whether this light striker spring gives you light strikes.

The Glock uses a similar trigger system, but with the addition of a little spring that helps you pull the trigger. If you replace that fragile spring with a New York trigger it will raise the trigger pull a bit and make the sear more positive. It also prevents the most common failure in Glocks: the trigger spring snapping.


Sigma,
The striker spring goes inside the slide. The plate on the back of the slide is the accessway.
 
Picture available

I just received my new SW9VE and I have ordered the 3.5# Wolf striker spring. It is not crystal clear to me what the rear slide cover plate retains. I am familar with the Glock but the rear of the Sigma slide is much different.

Can anyone provide a picture or drawing of the dissasembly process?

Rather than, due to inexperience, believing stories of "extremely light" trigger pulls on Glocks, why not just avail yourself of a factory stock Glock and a trigger pull gauge and give 'er a pull? Stock Glocks with the 5# connector and "standard" trigger spring generally pull @ around 6#. Does that sound "extremely light?" ;)
 
No, 6 pounds sounds just like many stock single action triggers, like that of a basic 1911.

Extremely light for a safetyless DA, though.
 
I think unintentional discharges from Glocks could stem from having no safety that actually locks the trigger/striker. If you have it in Condition One, shove it into a holster and something small gets in the way, it could very well press the trigger. On guns with a locking safety this danger is reduced.

If too light a trigger on a Glock bothers you, there's always the 8# NYPD trigger set!
 
Strange followup comments

I have the desired SW9VE dissassembly information now. Not sure how my question set off the three subsequent light trigger and Glock comments but, oh well....

I the Wolf 3.5# Striker Spring comment was the catalyst, well that spring reduces the SW9VEtrigger pull into the 6 pound range, I am told.
 
I think folks who think that a 6# trigger is "extremely light" need to get out more. :p A 6# trigger on a 1911 is considered to be a pretty crappy trigger.
 
I have had the 3.5 on my SW40E for a while now.

I have noticed a few (maybe 1 or 2 per 100) light strikes using blazers aluminum 165 grainers.

Not bad... don't know if it's the ammo or the spring.

Takedown just like the glock.
Best, Coop
