Title: Witness Hunter issue smoked out
Post by: Intercooler on January 14 2014 07:19:27 PM MST
  My last shooting session I put it to the Hunter and encountered a problem almost at the very end. The slide wouldn't lock back at all and the trigger wasn't resetting. I haven't been able to duplicate the trigger issue at home but tonight I looked at the slide issue.

Through trials tonight I found it.

I pulled the Hunter stop

Hunter and Limited stops

  The Hunter stop looks a little weathered but swapping them did nothing. The slide still wouldn't lock back! I tried another K10 magazine and back to normal. At that point I looked inside to see what was going on as I pulled the slide back. What I saw was the pin being pushed out some allowing the stop to not catch. That and just not enough tension on the stop from the follower to engage it! It looks like something caused wear or movement in the follower and a nice ridge on the side. That part may be related to my stop being wore a bit and I'm asking the gurus now.

In all the magazines I have looked at to date the slide stop just doesn't extend in far enough for my liking. If nobody out there sells an extended version I will ask Henning if he can do one. The short term fix is order a bag of K10 followers.

Unacceptable!

The Limited is the same  :( All of them will be!

I sent Henning a note about making a stop. He is in Shot Show right now, but might still respond. If he isn't interested I may talk to my Smith to see if he can modify my four. They can even be a little longer and we could file them back for a custom fit. Allow about .005" of clearance to the step and you are golden!

You may want to have a few extra of those, give EAA a call see if the will send you one.  It doesn't hurt to ask about replacement of a worn part.  They may take care of you.

Here is mine. It looks like your Slide stop is bent away from the frame, also.
But it dos look like you could add a 1/16th or so to the slide stop.

On the trigger reset issue.  Have you tried duplicating it with these steps:

empty the gun and prep for dry fire (safety first)
dry fire, keeping the trigger depressed.
rack the slide (don't cock the hammer manually, let the slide do it)
release the trigger for reset.

My experience with my Match has been that when I adjust the take up screw right to the limit, after a couple hours crud will build up in the trigger assembly and eventually I have this issue.  Cocking the hammer by thumb doesn't reveal the issue as I pull the hammer further back than it gets moved by the slide.

As far as the magazines, you may just have to look at followers as a part that wears and needs replaced.  What is the round count on the magazines in question?

I think it's crud from the last session. It didn't do it last night.

The magazine is a recent buy. Possibly 200 rounds on it.

$36 for a new slide stop and $5/ea follower.

  Henning responded with a maybe. That's encouraging since the last time it was the same deal with the flat bottom firing pin blocks. Now I have them in all four!
Title: Re: Witness Hunter issue smoked out

Yeah...Only 200 rounds on it is not something that should fail.  I was expecting 10K rounds being a reasonable service cycle for a plastic follower.

   Like was mentioned it looked like my slide stop was bent some. It could have happened when the whole mess started. My info from EAA showed the parts didn't ship until Friday, but I have Chronograph testing to do today. I decided to put a new K10 mag in and work the slide stop.

    I put the round end in the vice and gave the slide stop end one whack with a dead-blow plastic hammer. It bent it back just enough to be a couple of thousands from frame contact:

   I took a triangular file and deepened the trench some for more positive engagement of the retaining spring that holds the stop in as well:

  It feels tight, no malfunctions and I'm ready to roll!

  Flawless today! The stop didn't budge, no mag issue and the slide locked back on every empty magazine. I think the stop on the way will be a spare.

I wonder how they are being bent?

  I have a theory on what happened here. I think the slide stop moved out a little and caught the follower upon travelling backwards on the outside edge. The day this happened, I shot a bunch of high end stuff! Deepening that groove will allow the spring to sit deeper in the stop metal and not move. In looking at the stop the way it comes from the factory the groove doesn't seem real deep and especially for high impulse stuff. I ran all those big rounds today and it didn't budge.

On my new Hunter, I can't push the stop out, without ether taping on it with something
like a hammer or pushing it up against something hard.
Since yours was used when you got yours,  how easy has it been before this too remove it?
Title: Re: Witness Hunter issue smoked out

   It was getting easier each shooting session. I just tried pushing it out and couldn't do it with my fingers. Next cleaning it will have to be tapped out again. I popped the magazine with the tore up follower and it works flawlessly now. I think making that trench a little deeper just helps things, especially as wear starts to occur. The next shooting session I think I will touch up the edge of the hurt follower with sandpaper and give it a go rather than changing to new.

   The ladies and EAA generally flat out suck!

I asked for "Black" "K10" followers and this is what showed up >:D

These shouldn't be on my dime to send back. I don't even think the reds will work with my K10's!
Title: Re: Witness Hunter issue smoked out

Classic EAA. They won't give me a paid label with RMA #. On top of that they charged me $10 for a $5.15 USPS shipper and had the weight on the invoice marked 4 lbs. Yea... Okay!

    I seriously need to find another source for all Tanfoglio parts.

You know, I think I read about where those long guides on the red followers, were cut shorter to alleviate some issues of feeding.  They are long, when the magazines are fully loaded, they tend to be distorted at the very bottom and that increased drag as the follower is trying to slide up the inside of the magazine.  That extra drag caused misfed ammo and in some instances it bound up/stuck inside the magazine, with the cartridges loose inside.

Good luck IC  ???

You should have heard the BS lines she gave.

- Our policy not to give a printed label
- We don't have a way to give you a printed label
- We are at the mercy of our supplier on what parts get sent
- The $10 included a tracker
- I checked with service and they said the reds "should" work


If you know anything about any of the above... Hogwash!

  I sent it back on my dime. In the future I will go to great lengths and possibly even used to avoid them!

   At any rate, it's a $16 loss for nothing. To top it all off I looked at the replacement slide stop and it's a dull finish unlike the Hunter slide stop. Many of the replacement parts aren't as expected it seems.

Keep the red followers and tell them to send you the correct ones.

On their dime.  ;)

  I would love to do that, but she told me they have only heard of the black followers... None in stock. That's when she said they only get what the supplier sends. I'm going to look up North to Canada next time I need something.

Paid the Piper... EAA got it right the second time.

Well crap!

These are not replacements for the K10's as can be seen. What to do?????

You can see my damaged K10, which doesn't function correctly in the pistols versus what they sent. If it functions okay it doesn't have the huge pad underneath and may hold 15 instead of 14. Still not right! Let me go grab 15 and see!

Title: Re: Witness Hunter issue smoked out
Post by: Intercooler on April 21 2014 05:50:08 PM MDT
Nope! Still 14 which must be based on the follower overall length. The center portion must just be a location, anchor for the spring in the K10.
