    Don't ask them about a "trigger mod" or they will get all huffy with you and won't do a thing for you.However, if you complain that the trigger pull is gritty and 'catches' as you pull the trigger, they'll have you send it in and when it comes back to you it will be all slicked up.

    One note, the newest ones have the pins "peened" in the sear assembly to make it very difficult to take it apart and clean up, probably a liability CYA by S&W.

    For those low shooters, here is a shot of my 40VE with the Glock HiViz sight installed. Raises your POI about 2" at 25 yards.

    Thanks for the additional info mogunner.
    I have a low shooter, but it has nothing to do with the sights, it's the hard trigger.

    I have two Sigmas, and have done the trigger mod on both of them, I would consider them to one of the best point and shoot guns for the mony on the market. They will shoot anything that I throw at them, and do it with consistancy.

    I had an SW40F and I really liked the gun...except I hated the damn trigger. I wish I had found this prior to getting rid of it.

    Same here.. my Sigma shot flawlessly and dead on! I loved it but my finger didn't. After 7 shots, I was done for the day!

    I found this trigger kit for the Sigma at Apex Tactical and was wondering if anyone here has tried it.
    They have a video on how to install the kit which looks straight forward. I would think for $20 bucks you can't go wrong, and could always revert back to the original springs if need be.

    I just installed the kit in my Sigma VE9 tonight, so hopefully I will be able to get to the range this weekend to test it out. I notice a significant difference when dry firing. It took me a couple of hours to get everything done. I had a little trouble getting the stricker block spring out, but other than that work on the slide was for the most part easy. The trigger return spring was easy to take apart, but putting everything back together was a real bare. It took me 1-1/2 hours. I think the main problem was my eyes, and the lack of good light. Not an easy task when you where bifocals. If you have good young eyes it shold be easy.

    That's pretty cool, actually coming from the tech. Tells me they know a lot of people are going to do what it takes to modify that trigger. I figure that os exacly what I would do, put in the original springs.
