I'm new to the Forum and was wondering if you could recommend a trigger spring conversion/mod for the Sigma 9mm that would decrease the "pull" resistance and lighten it up a bit similar to the Glock? Other than the trigger, I've been very pleased with the performance of the Sigma handgun. However, the heavy trigger pull after repeated shooting tends to cause fatigue and effect accuracy while on the range. Thanks.

I removed the pigtail spring from my trigger and that lightened it a bit. You can polish/smooth up the sear or whatever you call it in a striker fired gun. Anyways, that will smooth the trigger but will not reduce the weight much. Some have suggested using a reduced weight striker spring but I don't want to chance a light strike with my gun. At the end of the day it's a long trigger, much like a DA revolver, and not much you can do about it besides buying a Glock :-) Search on Youtube for Sigma trigger and there are a few videos showing how to smooth eht trigger a bit.

First, go to the Sigma & SD Thread

Smith & Wesson Sigma & SD Pistols

Then read post 13 of this thread: (I wrote it)

I completely changed the trigger pull and feel without removing or replacing any springs.

Happy shooting!

PS: You'll find a lot more about the Sigma trigger on the Sigma & SD thread than the Smithing thread.

I bought my 9ve used a couple months ago and have about 600 rounds through it. I bought a lightened trigger spring from this guy- SIGMA Trigger Fix DIY Spring Mod SW40VE SW9VE Smith & Wesson Walk through Beginners - YouTube wanting to try it out. I'm not new to smithing, but it's been a while. I can't even get that first pin out to release the sear block. Could this have damaged by a previous owner? Any tips?
