MikieM Posted August 19, 2017 Share Posted August 19, 2017 (edited) A good friend of mine has a Tanfo Stock II with all the parts necessary for a good trigger, and like many here he uses Winchester primers but has to take what he gets as far as seating depth goes. To help with the problem he removed some material from the BOLO to gain a bit more arc in his hammer, as per a recent thread outlining how the job could be done. He says he removed .006 from the BOLO. So here's the deal. At the match today he had at least five failures of the trigger to reset during SA fire. Could he have removed too much? And, if so, what might be the remedy? Thanks, Mike. Edited August 19, 2017 by MikieM Link to comment Share on other sites More sharing options...
Nathanb Posted August 19, 2017 Share Posted August 19, 2017 Could he have? yes how do you fix new bolo Link to comment Share on other sites More sharing options...
SoCalShooter69 Posted August 20, 2017 Share Posted August 20, 2017 (edited) Where specifically did he remove material from? SA reset comes from the amount of the curve on the disco. So I'll need a little more information to diagnoses the issue. Is his sear spring bent? Was his gun really dirty? There are a bunch of things that can cause a failure to reset in SA... Removing .006 off the nose won't effect SA with the bolo. Edited August 20, 2017 by SoCalShooter69 Link to comment Share on other sites More sharing options...
MikieM Posted August 20, 2017 Author Share Posted August 20, 2017 Oh, did I mention he was left-handed, and when he bought the gun he moved the mag release from the left side to the right side. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted August 20, 2017 Share Posted August 20, 2017 And is he running the factory plunger spring, uncut? Link to comment Share on other sites More sharing options...

noshootmagnet Posted August 21, 2017 Share Posted August 21, 2017 I'm Mikiem's friend. The problem occurs on the last round of the mag. When the last round is stripped from the mag, the trigger doesn't reset. Hit the mag release and it will reset. As mike said, I am left handed and switched the mag release to be lefty friendly.

So basically this has/had absolutely nothing to do with the bolo, but we're blaming the bolo in post 1. Switch the mag release back, my man!

johnbu Posted August 21, 2017 Share Posted August 21, 2017 (edited) "Switched mag release. ONLY occurs on last round." Sounds like the height the mag is held is off a bit or it's being pushed off to the side and is rubbing on the trigger bar. If a mag is contacting the trigger bar, you need to find out where / why and correct it. The last round has the weakest spring force and that is a clue. I would PULL the mag down and PUSH up while cycling. (Snap caps or at the range!). If that causes other than last round fail or fixes it, then adjust the mag hold accordingly.

On a feeding problem, that the shooter switched the mag release?!!! How is that even remotely related to the trigger system, let alone the bolo? I got a good laugh out of this thread. Enos forum will blame the bolo for anything. Lol Link to comment Share on other sites More sharing options...

No where did I say he had feeding problems, did I? He has trigger reset problems. Don't point out my failures when, obviously, you have several of your own. Bad manners being chief among them.

Here's how the OP should have gone: I have a buddy that is having reset issues (list symptoms). He is left handed and switched the mag release. He switched the mag release back to how it's supposed to be intalled, originally, and the problem goes away. Can the mag release be switched or modified?

SouperMan Posted August 21, 2017 Share Posted August 21, 2017 I wonder if the set screw for the trigger overtravel has worn down a bit that it's not allowing for a reset with the magazine pushing up on the trigger bar. Link to comment Share on other sites More sharing options...

If I'm not mistaken the over-travel screw was removed. Right now I'm leaning towards the notion that a magazine is bearing against the trigger stirrup. Won't know for a while.

Becuase while he's knowledgeable and helpful much of the time, whenever someone criticizes his babies, ARy/SoCal goes into full on "momma bear" mode and only sees red. Let us know if flipping the mag catch helps things. Then measure that sucker on both sides and see if it's holding the magazine up higher. For the record... I'm a lefty with the Titan/Bolo/sexysear combination, and my gun didn't have any issues with a flipped mag catch.

B21 Posted August 22, 2017 Share Posted August 22, 2017 I'm a lefty and have some mag problems with the mag catch flipped. Mine wont reset in double action on a empty mag, does it on about 50 % of my mags. Doesn't really matter so I just gave up on worrying about it. Never had any issues with it not resetting in single action. I'd be willing to bet it's holding the mag up a little high? Link to comment Share on other sites More sharing options...
MikieM Posted September 5, 2017 Author Share Posted September 5, 2017 (edited) As it turns out (sounds like the name of a soap opera on TV) the mag release was the problem, after being switched from the left side to the right side. The release is (was) evidently holding the magazines off-center enough to where they impinged upon the trigger stirrup enough to cause a failure to reset. Quality control at Tanfoglio is highly suspect. Edited September 5, 2017 by MikieM Link to comment Share on other sites More sharing options...

Are you sure it's not the mag having the slots slightly different on each side? Link to comment Share on other sites More sharing options...

We thought of that (among other considerations), but all 6 mags checked out to be dimension-ally correct. The test was simple enough. With the old mag release reinstalled (as per a right-handed shooter) everything worked fine again. When switched back to a south-paw configuration the problem came back. A new mag release from PD, installed for a left-handed shooter, has worked fine thus far. Link to comment Share on other sites More sharing options...
