ALO11

Johnbu, you mentioned something that caught my interest - #7 in your list. I run a long slide spring. But I would imagine a lot of tangfo owners run a long slide spring as that is what Henning sells. I have an 8lb long slide spring so in a regular length slide should equate to a 10lb, or at least that's what is said on the website. I would imagine anyone running springs from Henning is running a long slide spring.

Reaper1, which spring did you get and where did you get it for the lighter extractor spring? I posted about the very same issues (you actually referred to my thread in one post and it sounds like we also both shared in the frustration that we paid a lot of money for a gun and basically have to gunsmith it to run reliabily. I was about to give up and switch to CZ...that's a risky thing to say on this forum haha). I also came to the same conclusion and mentioned in one of my posts I thought it seemed like it was either the extractor or too tight of a extractor spring. I ordered a new one though and changed it out, but that didn't help, so I went the route of buying stronger mag springs -basically to force the round into position when the mag is almost empty (2nd to last or last round). This seemed to have solved the problem but it's a band-aid IMO. I have to buy a stronger mag spring and change it out for every mag I buy. I didn't know they sold lighter extractor springs. Also I know I know, a lot of people will say my breechface needs to be polished more, but I have and I don't feel any burrs.

So here's the update on the FTF's. Sorry it took a while, been dealing with the aftermath of the flooding here in Louisiana. I put the extra power mag springs in and broke down the slide center ribs front edge by radiusing and polishing it. So far I've only been able to do one range trip so I'm not yet calling it complete success, but it's definitely promising. I fired 250 rounds through the gun using all 3 mags with no feed problems. I started with the mag that was giving me constant FTF's and put just under 100 rounds just through that mag. I would only load 6-7 rounds in each mag to give the gun more opportunities to have the problem as most of the feed issues were on the last or 2nd to last round. I was firing American Eagle 124 and 147 gr. With only 250 through it I'm hesitant to say my issue is resolved but by far this is the longest streak with no issues the gun has had.

YVK, the pictures above may not be the best but most of the time the round seems like it starts to go in the chamber, and the round does not go all the way up on the breech face under the extractor. I actually can bump the back of the slide and make it chamber correctly. That's why I originally thought maybe it was my extractor and bought another, but what are the odds of both extractors being bad, low I would hope, or else we need to start questioning tanfos manufacturing and quality assurance. I have previously polished the breechface (not necessarily mirror shine) but can't see or feel any burs on it.

I'll go ahead and give polishing the center rib, breaking the rib edge, and getting the extra power mag springs a try. Which extra power wolf mag springs did you get, the +5% or +10%? I do have to say though, I would have thought a stronger mag spring would make the round underneath slide out more as the round above is chambered due to being pushed against each other more and therefore higher friction, but hey at this point I will try anything to get this gun reliably functional. I'll report back after I get everything implemented and have a range day under my belt. Please keep the experiences and suggestions coming people. Thanks!

What sort of things would I notice if its what you mentioned? What made it obvious to you that it was a defective mag catch and a mag seating problem? My mags seem like they go in just fine, and release fine.

Only thing I have to add, is that I use blue magic too, and it's the sh*t. So is the intention to actually remove metal and radius the front rib edge so it is more rounded than square?

I already polished the breech face and rib somewhat, but could probably do a better job. Are you basically trying to chamfer the rib edge so it isn't square? How tight does your case fit under the extractor? For both my extractors it takes a little force to get the rim to slide under the extractor and I can shake the slide vigorously and the bullet still won't fall out, hence why I originally thought maybe the extractor was too tight and bought another one, but the new one was the same. I will say, if this is indeed the problem, you would think for a gun that cost this much you wouldn't have to "gunsmith" it to run correctly.

Let me start off by saying, new to the forum and sorry post is so long, trying to provide supporting info. I have read a couple of threads on this topic but none of them seem to have any real resolution, and I'm starting to get discouraged with my fairly new purchase... Here are all components in my stock II 9mm before people ask: - Wolf long slide 8lb recoil spring (so as I understand it in a stock II that has regular slide length it's the equivalent to a 10lb recoil spring) - Wolf reduced firing pin spring - Henning gen 5 firing pin - EGD extreme light hammer spring - CGW reduced firing pin spring for trigger plunger spring - CGW reduced sear spring - I have done polishing on the components (trigger bar, plunger, hammer sides, breechface, a little on sear, center rib on slide) but haven't gotten crazy with this as it's not that big of a deal to me to chase the lightest possible trigger pull With all the gun internal facts out of the way, here is what is getting me down and frustrated with the gun. I am having failure to feed problems and can't figure out how to resolve them. Usually happens on 2nd to last round in mag, sometimes on last round. My gun is fairly new, probably 1k-1.5k rounds through it. Has been happening since the beginning I believe (I installed lighter recoil and hammer spring shortly after I got it, and only had one range visit with stock spring so I don't remember if it had FTF issues with stock spring or not, but to me with everything I've read and people I've spoken with, the gun should run fine with the equivalent of a 10lb recoil spring so that shouldn't be the issue). I thought it may be the extractor so I bought a new one from EG's website. That didn't solve it. I didn't change extractor spring because I would think symptoms of worn out extractor spring would be failure to eject not feed (atleast in my mind). Thought may be stock mag, bought 2 other EAA mags from patriot defense, fails to feed with each one. One so much more frequent than the others and I noticed the follower can be angled up when the "nose" is pressed on unlike the other ones making you think a double feed could be likely (pic attached). Polished breechface to make sure there are no burs catching preventing rim from going under extractor. I've tried several brands of ammo, happens to each, some more than others. I've cleaned extractor removing any carbon buildup often. I can't isolate the problem, so this becoming a very frustrating issue. I love the way the gun shoots but the reliability problems are getting me discouraged with the purchase, I haven't even brought it to a match yet because of them. It's getting very costly to troubleshoot because each time I try something I have to run at a minimum 100 rounds though the gun to get an idea if it worked, that with a range fee each time is racking up money. Please help out someone who is new to tanfos! Is there a gunsmith or someone who is known in the tanfo community/industry who is a guru and works on these? I just want it resolved and shooting reliably so I can actually use it do what I purchased it for. As soon as I figure out how I'll attach some pics (doing this from phone right now)

Hoping for help with ongoing failure to feed problem with tanfo 9mm stock II
