Hi Everyone

New to forum, and just purchased a New Sigma 40 @ Cabelas for $285. Could not pass up on this gun for this price.

Took to range and it fired flawlessly , shot 100 rounds Federal 180g FMJ. Really like the feel of the gun and the way it fired.
I shoot revolvers , this is my first modern day Semi Auto. My only other semi auto is a Ortgies 7,65 Browning made between 1922-1925. This being said, with all the complaining about the trigger on web, trigger feels just fine to me.

My only question about gun is if it has a firing pin block of any kind in case its dropped or banged really hard ? It is safe to carry cocked I assume. The only way for a discharge is to pull the trigger similar to a modern revolver ?

My Ortgies is a striker fired as well , but is designed in a way that the striker is under tension at all times with no block , if it is dropped or banged really hard it may Discharge. This of course is an old design. Thank You .

It has two safeties to keep it from firing if dropped: The articulated trigger (not enough mass in the lower portion to "pull" the trigger if dropped), and a firing pin block (the button on the bottom of the slide) which blocks the striker unless the trigger is pulled.

No way to "cock" it. The sigma has a double action only mechanism, the striker is "cocked" by pressing the trigger.

Basically very similar to a DA revolver, That's great to know. This is one reason I have always carried a revolver.

This is what gives it A long supposedly hard trigger pull. I like it even more Now. Thanks Marlin 357.

The more you shoot it, the more you'll like it!

Sigma don't fire unless trigger is pulled/sigma fires everytime trigger is pulled!

Welcome to the forum!

Welcome. I bought a Sigma 40VE about a year ago. I am very happy with it. I have never had a jam or fail to fire. It fires anything I buy. I am a revolver guy too and my Sigma is the closest to my revolvers. You will enjoy owning one.
Regards,
Howard

Welcome! I've got the 9mm version. Paid a bit more than you did, though.

Dang it.

Welcome..... I have the .40 Sigma. Best damn gun I have ever owned. I carry it everyday as my CC gun.

I liked it too until i tried an SD40.I now own an SD40.But the Sigma was a good gun.

I bought mine two years ago. Took it to the country shot four rounds. Took it home cleaned it and qualified for CHL the next weekend.
I like the feel of the 40 over the nine. Great pistol would recomend to everyone.

Thanks for all the info. I have another stupid question.

I use Hoppes #9 to clean all my guns which are Blued or Matte Stainless steel. Works well and never had a problem using.

While cleaning My New Sigma, I realized , this stuff may not be safe for Polymer ? Kerosine melts some plastics, I only used on slide and Barrel , wiped metal parts within polymer housing lightly with Q Tips getting very little on Polymer.

On another forum, a lot of folks said they use Hoppes #9 on their Polymer guns, with no problems. So I came up with the brilliant idea to email S&W about the Polymer used in manufacturer of the Sigma and use of Hoppes #9. Their reply , #9 may harm the finish on the slide and mentioned nothing about Polymer.

Now I have scrubbed My Stainless Revolvers With #9 and have never noticed any harm to finish.

What do you guy's use to clean your Sigma's Thank You

I usually use Hoppes solvent in the barrel and slide interior, and CLP elsewhere. I don't concern myself with the poly, light wipe down with an oil rag.. FWIW

I did a lot of research before purchasing a conceal carry pistol, and this is the one I settled on.

One of the reasons I decided on the Sigma was the fact that the firing pin is not under tension when I am carrying. At first I thought "No safety! Are they nuts?" but I eventually figured out from reading various forums that it has the same kind of safety a revolver does...the firing pin is at rest unless the trigger is being pulled. Because of this, there is no way it can "accidentally" go off and put a new vent hole through my hip as I carry it...a feature that has always seemed important to me.

Just in case you have not picked up on this, the main complaint about the Sigma is the trigger pull. People go on about it like it requires forearms like hams to pull. The truth is that the heavy trigger pull is (in my estimation) EXACTLY like a revolver trigger pull when the hammer is not cocked back...because it is doing the same thing. When you pull the trigger on a revolver, you are both cocking it (during trigger travel) and then releasing the hammer at the end of the pull. The Sigma is doing the exact same thing, except it uses a firing pin instead of a hammer. As you pull the trigger back, you are storing energy in the firing pin spring for the release, then at the end of the pull, the pin is released and the stored energy drives the pin into the firing cap of the round, making it go "bang!".

Because of this, there is no way to fire a Sigma by dropping it or accidentally tapping the trigger when you were sure the safety was on but it wasn't. It ALWAYS requires a full trigger pull for each and every shot. The added feature of the articulated trigger adds an additional level of safety which blocks the cocking mechanism if the pull is only on one section of the trigger, as it would be if the trigger got snagged on something as you were drawing it.

I think this is the key to making peace with your Sigma: don't compare the trigger weight to a Glock, (which is cocked for the first shot and automatically resets the firing pin for the rest of the shots), compare it to a revolver. If you can fire a revolver from a non-cocked position, you can fire a Sigma. I have fired my classic S&W Regulation Police .32 revolver and the Sigma .40 right after each other, and the trigger pull is almost identical. I have also let a middle-aged woman and a sixteen year old girl fire it and they were able to fire it with no trouble. Yes, it did require a little strain from the teenager which would probably affect her aim, so this is no more suitable for her than a large revolver would be. But the point is, she could fire it.

Personally, I consider this "double action only" construction to be a much better safety feature than any safety lock on a double-single action handgun.

Bottom line: I would rather it have a trigger pull like a revolver than rely on a tiny piece of metal holding back a spring-loaded pin to keep me from blowing my right leg off.

I agree with you (M@ROb). I like the trigger, was shooting again last weekend . I shoot and carry a 357 Revolver ,This is my main carry. I have practiced shooting double action with this revolver for years. I agree, I do not see the Sigma trigger as a flaw.

The fact that the gun is as safe as a revolver, makes it so much better !!! I will feel safe carrying, which was not my original intent. The more info. I get about this gun, the more I like it.

This gun was pretty much an impulse buy for me, received cabelas ad, did some quick research, stopped at Cabelas on the way to rifle range next day. Liked the feel, liked the look, really liked the price ($285). So far this gun has turned out to be perfect for me. Easy to field strip and clean Too.

I have put 250 rounds thru so far, and 50 were that Russian Tulla stuff, shoots flawless so far.

I too just purchased a sig 40 and i am pleased with it although would like to take the trigger pull to 5-6 lbs. will S&W do this or does this have to be done elsewhere and does it void warranty?
Anyone have any ideas, I read one guy sent his back to S&W and they fixed it. No details on what they did though.

Read my post #16 on this thread for a detailed description of a trigger fix that keeps all parts intact.

Kudos on your purchase....I've had mine for about 2 months, no complaints after 3 range visits, and I even smile when all the BS flies on the other forums when they repeatedly put it down....

I enjoy reading the pros and cons of this forum on the Sigma. I have a Sigma SW40C (made in 1995) that I bought in 2000. It was an "experienced" law enforcement gun used by a sheriffs department in southern IL. It has given great service over the years. Qualified for my CHL with it. I take it to the range about every couple of months and dry fire it regularly. Wouldn't trade it, (don't believe in getting rid of guns just accumulating them). Just my opinion.
