Acting as Rangemaster the other day, one shooter had a Sigma .40 that was giving a consistently light primer strike that resulted in many failures to fire.
One local range has a Sigma that evidently fired unlocked and did a self-destruct number.
1. Are these pistols safe to use as a self defense weapon? 2. How would one go about correcting a light firing pin strike? 3. Has anyone else had experiences with a Sigma similar to the above?

Hello, Mr. Lawson. First, I've never owned a Sigma and am not familar with them other than having seen about 6 or so come through CHL classes I teach. Not one worked through a full magazine w/o either failure to fire, failure to feed or failure to extract.

I've read that this has since been corrected, but have not kept up too much with it as I simply don't trust Sigmas.

The ONLY Sigma pistols that I've seen work have been the little .380s and I think they have a rather limited lifetime; I'm not positive on that last point.

Others may have positive experiences with Sigmas, but I can honestly say that I've never seen the full-size version work.

Best.

Hi John
I have worked on a lot of SIGMA Pistols.
When I did see a light primer strike it was usually because some one installed a weak striker spring or a spring that lost its tension.
I think if you remove the striker assembly make sure the tunnel it is in is clean and free of brass particles and install a new factory standard striker spring, that will help.
As for it not going into battery check all the lock up area to see if something has been peened or damaged causing an obstruction.
Getting back to the striker assembly check the plastic cups for wear or if they have deteriorated.

Regards
Teddy

I carry a SW40GVE every day and run about 150-200 rounds through a month. I have had a couple of FTF issues but nothing chronic. I very much enjoy the weapon but I would like to do a trigger job on it seeing as it has a very heavy pull. Other than that great defensive weapon and every day carry.

Although that might be because I have one of the newer ones that they have fixed most of the issues that plagued the first generations of sigmas.

Did you notice how old this thread is? Camp died a few years ago. Lawson would be over 80 if he's still alive. Jacobson I don't know; haven't read anything by him in years.

Well sorry to hear about Camp. Trying to keep tabs on my own carry weapon and the sentiment surrounding it. Who knows maybe because of you and I this thread will be resurrected lol

Ugh, I sure hope not. Too much of that goes on here already. If this place had some moderation/administration they'd cut back how far in time one can go via the search engine, and maybe archive these ancient threads.

I'm glad we can still get to the old threads as some contain useful info. Just wish newbies would pay more attention to what they're doing.

I second that. I've come to a point where I laugh about old threads being resurrected, but I have found pertinent info on a lot of forums that was very old. Especially in the world of firearms. There are some guns that don't change a lot, and some problems that don't go away. Eventually, someone new will happen upon one of these "older" variants and face an issue that had been addressed some time ago. Too, they may not know about an older recall or similar issue if the previous owner hadn't done it and there's nothing recent floating around about it.

On the subject... I bought a Sigma 40 back in 98 and it worked 100%. It did indeed have a heavy trigger pull, but it worked great. My younger brother bought a 9mm version and it too has worked like a champ. WIth old 10rd mags and newer mags that I think are 15rd. His gun was also a late 90's pistol though.

I've had 2 students come through with the "New" S&W SD and they have also worked 100% but have some slight improvements. A slightly lighter trigger, tritium front sight(Though both are steel), a rail that was also on the later generation Sigmas (Like our's), and the melonite over stainless finish(Which was also available on late 90's and later Sigmas)....

Gotta be honest though... Asking about a Sigma on a Pistolsmithing forum is just asking for trouble. This is a group of folks who tend to like the finer makes and models of ALL classes of pistols. The sigma may work, but that is just the most basic, mandatory characteristic of a group like this. The refinements are what this crow is after... Unless I'm the only one with that perspective.
