Sigma Malfunction
I purchased a Sigma 9mm earlier this year. Cleaned it, put 250 rounds through it and then put it away. Several months later (yesterday), I took it to the range once more. I was shooting WWW and the trigger pull became more difficult with each round. At round six, the trigger pull was so heany that the gun did not discharge.
I swapped out magazines and the process repeated itself --trigger pull became heavier with each round until the gun did not discharge. At home, I field stripped the gun, blew it out with my air compressor, sprayed it down with Breakfree CLP and let it sit overnight,
Today, I wiped it down, reassembled the gun and took it to the range. It operated flawlessly. Later, I called S&W customer service and asked them as to what could have been the cause of yesterday's malfunction. He would not even venture a guess. He just said that if it happens again, I should return the gun to S&W for evaluation.
Do you have an idea as to what may have caused yesterday's malfunction?I used to be indecisive. Now I'm not sure.

I have a sigma 40S&W. I haven't had this problem but I have heard that the sigmas don't like alot of oil. In the manual it only calls for 4 drops. Maybe carbon buildup if you had to much oil on it. Just my guess

Dirty. Hose it out with Ronsonal Lighter fluid.
Go shooting.

Re: Sigma Malfunction
I'd look in the striker channel for debris.
You'll have to take the rear cover off the back of the slide, then remove the striker. A q-tip should get in there just fine.

Re: Sigma Malfunction
I hsve no idea as to what it could have been but, I have 1 question :
1) Do you use this gun as a self protection gun either cc or a bedroom gun, or is it only a range gun?
If it was me I would get rid of it if you lost any faith in the gun. I had a problem with a colt mustang pocketlight I was cc and it failed at the range. I will say this, colt customer service was wonderfull and the gun was repaired in 3 days but, I lost faith in the gun and traded it in 2 days later. I am not saying that colt would fail again but, I lost faith in it........Joe

Re: Sigma Malfunction
Not Suprised. I worked in retail selling firearms until not to long ago and had tons of problems with the Sigmas. Even owned one myself for about a month before I ditched it. Spend the extra $$ and purchase an M&P if you want a S&W. I know a lot of people buy the Sigma's because they are relatively cheap, but you get what you pay for.

Re: Sigma Malfunction
I have a sigma. It was ok when i bought it used then it started to jam quite a bit. I think i was using too much oil when cleaning it. I now rarely clean it and it has since stopped jamming. I use it in IDPA and it has not jammed once in competition. My two cents get a glock.... The price is never right.
PS - before i get burned for not cleaning it I am trying to shoot it into the ground so to speak to justify getting a glock. The trouble is it hasnt quit yet.

Re: Sigma Malfunction
I bought one in 40 S&W and while it worked it had a lousy trigger pull and was inaccurate, dumped it quickly. I have been burned by S&W over the years several times and now would only by older used revolvers made by them no pistols ever again or for that matter a new gun. I have always tried to buy American but will not be shafted by anyone.
