    SIGMA SW9VE Safety Question

    My everyday carry weapon is a S&W Sigma 9mm. This gun has been loyal to me, and I love it. I only have one concern, carrying it chambered. Now it has a tough trigger pull and my Fobus paddle covers the trigger. But reading online, considering there is no manual safety for this weapon, I am trying to get a detailed explanation of the safety features internally that keep this gun from firing unless the trigger is pulled. If I remove the magazine and pull the trigger back (looking in the magazine slot) there is a rail that rides with the trigger and depresses a small circle button on the slide. Is that a passive safety feature to block the firing pin from dropping without the trigger being pulled? If not what safety is there? I would like to know more on this topic to feel comfortable that this semi auto weapon will not one day decide that the grocery store needs a hole it the floor. Can anyone assist with this information?

    I am assuming that little round metal button blocks the firing pin internally, and that is the passive safety feature other than a 2 part trigger, which is honestly not very reliable.

    Everywhere I find online just says there are internal safety's to avoid this. Not that I dont trust that explaination, I want to know details to put me and my feets safety at ease.

    BTW, SW SIGMA... love it!

    okay after much research I may have answered my question, the firing pin safety in this animated demo of the functionality of the glock, is what i was referring to, it appears this button that is hit by the trigger is a safety feature to block the firing pin until the actual trigger pull. So i can rest asured it wont blow a hole in my foot or the stores floor without a physical pull on the trigger. Considering the SIGMA is almost an exct replication of the glock, I am thinking this is the built in feature.

    another thing to note is I can rest assured, that even though this pistol has the firing pin safety plunge it does not put any pressure on the firing pin until the trigger is pulled. The firing pin rests comfortably waiting to be primed until the trigger is squeezed, which explains the long and hard trigger pull, like a revolver. BEcause it is basically the same exact firing sequence as a revolver.

    Add this information for those SIGMA owners looking for it as well. Good to know I am safe!

    I have this gun. It is a glock in most ways as glock is paid $17 a unit by S&W after a judge said it was a glock. I call it a SWock.lol It goes bang every time and you can hit what you are shooting at if you take your time and pull the trigger slow. It is good for paper and a trainer. This is not a carry gun as i found out the hard way and a few of my friends (LEO) have told me as well. Most ever gun made today has a trigger block if not a safety as well. What they all don't have is a quick reset, clean trigger that any shooter knows equals lead on target. You do what you think is best but anybody will tell you nothing stops a threat or wins a battle like lead on target. If you know you can get a clean controlled trigger pull with a SW9VE in a real world need to use it, it will not be the carry gun of choice as you will know better by then. Good luck and good shooting.

    Well there's a glowing endorsement. I have owned glocks for years. Sigma's are clones, the only issue I have with them is the trigger & the circular guard. When or if S&W ever revises these, I will own Sigma's.

    I'm pretty sure they just use whatever ISAF buys them, but I didn't like the trigger on the sigma.

    not sure why it wouldnt be a carry gun, i am usd to the trigger pull, and it is reliable as can be. Only thing that I would like out of a carry weapon is a little bit smaller frame, but other than that, I love my sigma. I am one of the few that have lightened the trigger pull a bit though, not as much as I could, but it has been lightened some. I just thought that after all of the research, I would share the safety features in detail in case someone else wanted to know. Any other reason I am missing for it not to be a carry weapon?

    As long as you can make them count & put them on target under stress with it, who cares what you carry? Hi-Point, Sigma, M&P, Sig, Wilson custom combat pistol, or for that matter a flint lock.

    Lightened the trigger pull ????? Now that has done two things. One, This has made it a little better as the trigger pull is to long and hard to be counted on in SD to keep on target. Two you have just removed some of the only safety this gun has and that is not good. Your question about safety has new meaning. The more you shoot and get to know guns the more this will come to light for you. I own this gun and will only use it at the range and in the kayak. (it shoots underwater) This gun under high stress use, shoots 2 to 3 feet low as you are not keeping on target but taking in the action of what is around you and the rounds get pull down by working the trigger fast on a long pull. It has been seen on dash cams as LEO bouncing rounds off the pavement in a firefight. It happened to me and any speed or target shooter will not be caught using one so why would you in SD? In self defense use, the trigger break, being on target and getting the shot on the BG happens about three times faster than the sigma can be pulled. but you do what you think best.

    Nahh its still a pretty tough trigger, I dont want a hair trigger sitting on a pistol that is going +1 on my hip. It is barely any lighter honestly and still the classic sigma feel. Just not as grainy. I have put hundreds of rounds through this gun as well. so maybe that is the real reason why it feels a bit lighter to me, it really has no effect on my shooting. The factory springs are still in place minus the one pigtail spring that was put behind the trigger mechanism specifially to add just a hair of pressure to the pull. The differene is honestly hardly noticeable. Both of the other trigger assembly springs are factory, and the correct pressure. Maybe lightened isnt the correct wording, not so grainy. I spoke with a few local gunsmiths and I done research on the pigtail spring and it does put the griny feeling into the trigger, and it also causes a wear grove in the polymer right below the springs "end". This grove would continue to grow if it were installed.

    The pistol has not lost any reliablility due to this, and may have lost a slight pull on it, but it is smoother.

    I thought about having it re-installed, but the pressure isnt too much difference, i just dont feel like I am pulling my trigger through sand.

    As for the safety of it going bang due to a hair trigger, not a concern at all, I was just wondering about the pressure on the firing pin and the firing pin safety plunger... i wouldnt own a gun I didnt trust I would be able to defend myself with if need be. Thank you for your input though :-) Maybe different people are more efficient with different guns than others...

    I am very efficient with my sigma and hit very well with it and like it.. Please take the time to see what is said. I love my bolt action long gun and can hit an apple @ 600 yards all day long with it but do not want it in a close up and personal firefight. Being efficient and being effective are two different things. When you become efficient with a few more hand gun platforms you might see where the sigma has a disadvantage as a carry as i have and some LEO's that have carried this gun as well. Good shooting to you, I'm out.

    my 1911 has about a hair trigger and i have no problem carrying it on me every day as long as it stays in the holster it doesnt really matter what the trigger pull is - now the main reason i woulndt want a hair trigger on my sigma- yes i have one too is there are no mechanical safteys where the 1911 has 2

    now if my sigma had a hair trigger it wouldnt be so nice for carry - i have never carried it but may some day

    I found multiple mechanical safety's on the SIGMA earlier in the thread.... but something still just doesnt make me feel right about the light pull, that and i am used to this one now, dont really want to make much change at the moment.. i seen a buddy's glock last night, he went and had a ghost trigger installed... talk about a light and hair trigger.. but nice!

    I just read my post, it seems like I am being a jerk when I rad it, i wasnt trying to be, just woke up and had a direct choice of words, sorry for coming off that way. The lack of external safety's would make someone a bit weary though :-), until i learned how the firing pin works
