After speaking with one of the popular builders I have found that there is rotational play in my extractor. I have an egw hd and I use to have a aftec, I did not replace the fps when I put the new extractor In, this was 2 years ago.i have ordered a new fps it should be here next week I'll try that and see what happens. Shot the gun today using brass, no malfunctions and won HOA.

Magnetism? Are you picking up the nas3 cases with a magnet?
The cases I've been shooting are all brand new cases never loaded never been near a magnet in my possession.

The comment about changing extractor tolerance is a solution.
What happens if increasing coal? Is the barrel throated enough to accomodate a longer length? This may be an alternative solution.
Are you sure those cases are 'proper spec'? The rim and all.
Lastly, your extractor has little to do with the breechface concentricity to firing pin centerline. If the barrel is square to the breechface and the firing pin is centered, the extractor will 'flex' as designed.
Cases are in spec and very consistent across multiple cases. Unlike brass which has variance from manufacturer to manufacturer. Nas3 seem to be in the middle of the numbers if measured for the same part on brass variance.
Barrel can accept a longer oal. I've gone up to 1.181 with brass before. Have not tried with the nas3 cases.

What is the issue with heavier extractor tension?
Sounds like maybe there are other things at hand. Perhaps the centerline of extractor channel to firing pin channel are not in spec? If this measurement is off.. you are right, different tensions are needed. Alongside potentially other accomodations. If the tension needs to be that low, your extractor centerline may be a bit closer to the firing pin centerline than specification calls for. Is the extractor catching the rim at an odd angle? Perhaps polishing it with some fine stones will help.
I am not sure how I feel about those steel and aluminum cases..
Man, I would personally spend the bucks and run 38super/9x23 with starline brass. All that noise.. seems like a lot could go wrong with a bimetal case.
Could not a person electroless nickel coat their brass if they wanted that 'extra lubricity'? Either way, I thought the trend on nickeled casings was implied for carry ammunition to resist rusting and draging in magazine.
Nickeled tubes and well polished brass ought set you straight there. Even a well polished steel tube with some turtlewax buffed inside/outside.
You will need to investigate more to be certain of the issue.
In closing, I thought steel casings did not seal the chamber as well. Resulting in a more dirty firearm and less muzzle velocity.
Best luck, keep us posted.

I can't remember exactly what the issue was when I had too much extractor tension but I know when I got it to 18oz it ran like a champ. All my struck primers all appear to be dead center. No issues at all running brass. It seems the nas3 are more slippery than brass so they are being pushed further in the mag. And too far forward to catch under the extractor. Extractor and bottom edge of the breach face are recently polished and free of burs or dings.

Extractor tension seems light to me. 1.125 is 18 oz I set mine at 28 to 30 oz. weigend recommends setting to 25 to 28 oz
I've tried heavier this has been what has worked best with my normal brass cases just trying to figure out how to get these nas3 to work. I've always seen people say around 18-22oz but hey no two open guns are anywhere close to the same lol

Have you tried the rounds in other open guns?
I have not but I know a few open shooters that use these cases and have no issues.

I've searched and talked to a few people and can't figure out a reason for this issue. so occasionally with multiple 140s and 170s the round will chamber but the extractor will not be over the rim of the case, so the gun is out of battery. all of my mags are around .345 rear -.355 front. extractor is set at 1.125lbs of resistance, when I originally had the issue the resistance was at 1lb. the weirdest part of this it only happens with the shell shock nas3 cases. If i use brass cased ammo no issues. my rounds do tend to sit forward in the mag after cycling through. 9 major rn at 1.161 oal. been running this oal for 2 years. now just starting to have this issue when I tried to switch to the nas3 cases. I watched a video from atlas saying if the rounds are being pushed forward in the mag, then to radius and polish the bottom of the breach face. I did this and see no change. I am at a loss as what to try next. all 170s have new springs, 140s still have old springs but im having issues with all the mags.

Yeah I've read through a lot in this forum and there are so many conflicting opinions and experiences that its hard to really judge what is really common issues or special things to watch for with 9mm open. At matches I see more people having issues with 9mm open or open guns in general than any other division, ive been shooting limited a little this year and over about 3k rounds ive had absolutely zero issues and i dont go crazy with mag tunning and it doesnt need much maintenance. I know open is a different animal but im just looking for opinions on 9mm on reliability and things to watch for.
I've been running 9 major for the better part of the year. I've had zero issues, I run an offset cmore to avoid the potential ejection issues. Plus the dot is closer to the slide and feels more natural to me.

I have read a lot of guys spray the comp with Dillon case lube between stages. I haven't seen anyone do this but ive tried rem oil and either I'm not consistent enough with it or it just doesn't help, cause I still get carbon build up in the comp.

Very cool ,I wish more companies would offer a mount with thrumb rest. Im not a fan on how much the thumb rest can stick out from the side of the gun.

I'm getting good results out of the comp that is on the gun in this pic.
The comp next to it is untested. I'm thinking of trying a design with more top ports with a V shape to the holes to direct gas to the right and left at about 30 degrees.
That is awesome. I want one.
-
That blows, but atleast you have a diy remedy for it. I hould do the same. have you contacted the manufacture to see if they will warranty it?
-
Awesome thanks so much.
-
exactly what i was looking for. Thanks
-
Interesting do you have a link? I've always been a flat face trigger kind of guy but I'd like to get one to try it out.

Double alpha alpha x holster. Pricy but d#$n the thing is nice.
-
My vote is for the dpp. Have one on my co gun. I love it. I want one for all my rmr style optics I use.
-
Yes it is. I've shot stages where it was a single steel at 25 yards....I missed my first shot lol
-
When I first started I was always trying to rush to put the gun up, I thought it made me look cool, lol I now make sure the RO can clearly see the chamber is empty and I slowly give commands to shooters to make sure I don't miss anything.

Is there a formula or system to use with a specific weight recoil spring and the firing pin spring. Should I use the firing pin spring that comes with a recoil spring or is there a better system. Trying out different recoil spring weights should I swap the firing pin spring at the same time? Does the main spring come into play with this as well? Still very new to 1911/2011 firearms.
-
I would contact the manufacturer of the slide and try to get a better idea on actually specs before your order. And I have a scheumann for my 38sc and a kkm in 9mm haven't shot the kkm yet but I have heard great things.
-
Great tips.
-
Glad to see you got a fix for your problem did you change the spring as well?

New open gun will arrive next Friday. It's a true 5in barrel,(4.6 +.4 threads) binary eng 3 port com. I am switching up from my current open gun that has a 5.4in with binary 3 port comp. I'm loading 9.6 of no7 with a 124 fmj. I get roughly a 176pf. I'm curious how much I need to change my load for the new gun. I'll be using major pistol from shooters world. No popple holes in either. Both are 9 major. I know I need 9.8 of major pistol to get a similar load to what I have now. Curious to see what you all are using. For mid length open guns.
