Vid's Sigma 9mm, Pigs ear to a silk purse

I will say again Awesome videos. I dont know about shortening any springs or replacing with lighter ones. I am a pretty good revolver shooter and I like the heavy trigger in a carry gun. I know all about keeping your finger out of the trigger and all the rest but .. shirts get caught in there and what have you. To each his own

Now back to the video. I unloaded my gun and slowly pulled the trigger. Oh man what a sound! Crunch aint the word. I should also tell you that the only hand guns I have ever taken all the way down have been 1911's. I am by no means a gunsmith.

So I take it down to its little parts and first thing is the sear running in the channel feels like metal against sandpaper when you manipulate it with your fingers. Nasty catch in spots feel. Little fine emery board and it was solved .. now on to the trigger. Took out the pigtail spring and as he stated it was already eating through the plastic housing..

Warning .. after putting the gun back together th trigger did not feel one tiny bit lighter so pulling out that little spring is a preference. I figure if I don't need an extra part might as well not have it and I left it out when I reassembled.

The thing that was killing the trigger feel was the inside of that "s" like piece. this thing look like it had been cut using an angry beaver on a stick. the striations were incredible and deep. Striations doesn't seem like a good enough description. They were grooves!

As it dragged across the plastic it was amazing how bad it had been machined.

Took progressively finer emery boards to it. The grooves were so bad this took about an hour. I didn't want to remove to much material and the grooves were really deep. After I got it to where I wanted it I used a dremel with some rouge.

While the task took some time .. it really was very easy for anyone to do if they are the least bit handy. I was having trouble before keeping that front sight from moving before doing this and now it doesnt budge.

So if the only thing that bothers you is the crunchy trigger just do it yourself and dont bother being without your gun for a week.

I took out my pigtail spring as well. It lightened up my trigger. My accuracy was greatly improved being able to hit 3 out of 5 bullseyes at 21 feet. I will dissamble my trigger once again to remove these groves. The trigger is a small amount gritty. The trigger pull will still be heavy enough for daily carry. The safety mechanism still stands as to not worry about accidentally discharging the firearm. I'm really tired of hearing the horror stories about modified weapons and court. If your justified, your justified. If your not, your not. I'm going to make my gun be all that it can be, just like the army!
 
I'm liking my Sigma more and more. :) I am not a target shooter. Makes me madder than hell. But I can plink with the best of them. and my Sigma has turned into a wonderful plinker.

I took the Sigma out the other day with my new to me CZ-52. The CZ was a blast to shoot. Will be a war machine when I get it reworked. Hope to be ordering parts and finish for it real soon.

I had a blast with the Sigma. Once again I could not do paper justice be it 7, 10, 15 or 25 yards. Frustrated I went into plinking mode at this outdoor range. There was a gent. shooting a Sigma .40, and he was pretty good on paper with it. I let him shoot my 9mm and he fell in love. I had enough of my small tools in my range bag to do a quick job on his pistol. Just a fast clean up. He was a very happy camper!

We were the only people at the range that day so in plinking mode I started tagging small rocks, bouncing debris down range. Once wormed up I started putting pop cans out about 10 yards. I would pop them up in the air. Wait for them to fall below the berm then tag them again driving them down range. Best I could do was two air shots. Always missed on the third attempt.

There is soooo much to like about this pistol. What baffles me so much is the sorry attention to very basic detail and machine setup / production. The grooves on the cam side of the sear are insane! Any machine operator work there salt would refuse to run such sorry production. Same applies to the sear holder. There is no call for such sorry production. I come from a tool and die family. Spent my youth running production, die setup and other facets of the trade.

Really saddens my heart to see just how bad most American production is now days. Work ethic is in the tank, bean counters have screwed things up really bad. And most of our engineering talent is very sub-par. I see this every single day in my work life in the pump, boiler and chiller world. Also in the automotive, motorcycle and other production areas.

I went to buy a new motorcycle last year. Hell yeah! I'm going to go get me a new Harley. No,, not so fast cowboy. The welds on every bike I looked at were as bad if not worse than those done by Honda, Yamaha and others in the late 50's through the 60's. Weld splatter left on swing arms and just painted over. Chrome that would not polish to a nice luster and paint so orange peeled it made a golf ball look good. Yamaha got my money!

Same with cars. If it's not built in Japan. It's not in my driveway. I gave up on GM and Mopar years ago. I've even given up on Honda's and Toyota's built in America. There J-Vin cousins are far better cars. It shows,,, they are built by people that care. The product is better in every way! Less rattles and squeaks, far better fitment of parts and panels, better paint. It's unreal when you really start to look and live with them.

I'm sorry for the rant folks. I've been very upset with the over all lack of quality concerning our work ethic and production for years. And it even shows up in something as bone idle simple as a trigger sear. Really is a shame. :(

Not to be "That Guy", but what do you expect for $300 ?

If all those things you mentioned were taken care of at the factory, it would probably add $150-200 to the price tag.

Well you are that guy. lolololololol

What do you not understand about sub-par 3rd world class production? From a so called leader,,, not.

Have you ever setup a CNC Machine, water or abrasiveness cutting and finishing machine? Or ran punch press production or done die work? The diff. between junk and good concerning the sear and other parts in a Sigma is about 15 sec's production time per 100 lot if the program and correct cutting tools are used. The only fool that thinks the pistol done right in this 3rd world mode is the greedy and those that don't care. There was a time in America when this kind of work would have ruined a country of our status. Well I be damned it is ruining our country. Look no farther than GM, Ford, Mopar, Nasa, ITT and other producers.

Now does this mean it is worthy or should be built as good as a custom pistol? No of course not. But just look at the machine work! It's 3rd world crap!

And lets face it. Firearms tech has advance about as fast and as much as the development of the hammer. The only thing left to do with production tech is to make them faster, better and cheaper. If computers followed development and production like a firearms path. We would still be using a slide-rule and paper. And in current America half the slide-rules would be built wrong to start with.

Why don't you call smith and tell them that one of thier best selling pistols does not meet your approval and that they should take better pride in their work concerning the trigger group. If the trigger is that bad, just don't buy one.

I think you need to ditch the rose tinted glasses and take a hard look at the american "quality" you remember.

I have called them to let them know how bad the machining is concerning a few parts in a other wise good pistol. I also thanked them for at least making the parts of concern in a way they could be finished.

No rose colored glass's here my good person. I work with USA produced products every day in a industry that has advance at about the same pace as the firearms industry. I rep ITT Bell & Gossett Pumps and other ITT company's like Hoffman, McDonald Miller and other US major's in the Hvac, process and steam game. Quality has done nothing but gone down hill.

I think I'm going to go shoot my wonderful reworked Sigma today. And make some fire balls and put some bullets down range at 1700 fps with my CZ-52. :) Then do some work on my loading bench.
 
Just got back from the range and very happy. Removed the pigtail spring, big improvement. Trigger pull is better but still need to do alittle more polishing. Thanks for the great Vids.
 
enjoyed the videos...I am a revolver user but am looking into getting into a 9mm semi...your videos were helpful.....I am a novice
 
ok so i tore my sw40ve down and removed the pigtail spring. i felt a slight difference in the trigger pull. i checked the sear and didnt find any grooves anywhere. but i am not the first owner of this weapon so that issue may have already been taken care of. i did have one small wrinkle though. when i was re assembling the two stacked springs on the sear the longer inner spring shot off into oblivion. i broke out the surefire and searched the carpet but the spring is still MIA. i put the weapon back together and dry fired a few times. i notice a discernible difference in the trigger pull but it seemed to be functioning normally. my question is do i need to be worried about that missing spring or will it be ok without it? thanks in advance.

Removing the sear spring(s) causes the sear to reset slower, which may cause reset failure (think single shot) and the hotter the ammo, the more likely the failure.
The gun should not be relied on for defense until repaired.
No amount of testing with low-power range ammo wil reveal the problem, which is most likely to occur with hot defense ammo.
 
great. so anybody know where i can get another one of those springs? all i need is the inner one. the outer (shorter) one is still there.
 
ok one more question. anybody know what that spring is called? brownells has like 20+ listings of springs for my sigma. thanks for the help OKFC. your a life saver!
 
I've never done any smithing.....but plan to polish the trigger parts as outline on this thread. Will emery boards be all I need? And which emery boards? Thanks
