Range Officer hits Disconnector with slide. Suits pending.

Post by Jack H on Sat Sep 17, 2016 3:25 pm

Just noticed on new RO that slide distinctly bumps disconnector going forward.  I know one solution is the groove/ramp on the slide bottom.  Or should the disconnector be fit better?  The trigger pull/let-off of this RO is excellent off the shelf.  I hate to mess that up. 

I do have a new KC teardrop kit, but that is intended for a different gun. 

So can we fit the disconnector (at the top) without changing the trigger pull?
Will one of you hot pistolsmiths groove the slide off the gun?

Looked a little more at the gun.  The disconnector by itself in the frame pushes down rather hard and feels dry in movement. 

Perhaps a 10 mile trip to Roddy is in order


My other, first bought, RO had a crummy trigger.  I did put a KC Ax trigger in it described on another post.  But I later discovered flash at the mag release rubbing the trigger.  Until I cleared that off the frame even the Ax trigger was not so good.  Now it is most excellent.  I'll say again, roll or crisp to me does not matter.  It's the quality and my liking that counts.

My RO's have the same disconnect bump, though it is less noticeable with lots of rounds through it.  Both my RO's have the KC Ax kits in them, only solution would be to machine the Marvel ramp into the slide?

The Marvel disconnector cut only works for loading the first round from the magazine. All successive shots would not be an issue because the disconnect stays down until you let off the trigger and it reset. So I'm not completely a big fan of that cut even though I do it sometimes. A small radius on the front of the breech face and slightly radius in the top of the disconnector can alleviate the bump. I get the same Ransom rest results either way.

Interesting.  Working the subject RO slide by hand, the disconnector bump seems to be a harder bump with the trigger held back.  Significantly less hard with the trigger not pressed.

Try having pistol in battery. Pull trigger and hold to rear. Don't let off trigger. Hand cycle the slide. Ride it forward dlowly and should have almost zero bump. If corner of breech/disco rail is square could be issue. Also when you pull slide back with trigger held to rear look how high disconnector is in frame. Should be low.

Disconnector does not fall far with trigger pulled.  The slide then hits halfway up the disconnector's slope.  Pushing it down the rest of the way is rather hard (with trigger pulled). 

Just took off slide.  Something definitely interferes with the disconnector falling all way down with the trigger pulled.

Are you pulling trigger and letting hammer drop, then pulling slide to rear (while holding trigger back whole time) and then looking at disconnector? Then when riding slide forward does breech corner hit disconnector?

Yes.  Hammer down, hold trigger, work slide, move slide forward it hits disconnector which does not go down.  It's a solid hit.  Can be forced through though.  When all assembled the RO spring (original) does go through the bump. 

Let up on trigger, interference at disconnector is much less.

Definitely holding trigger back causes the disconnector to not fall or be pushed down easily.


Still the trigger let off is excellent.  If it were not for that I would s-can the whole trigger and put in the KC kit.  That might be a good trial.

Roddy, Roddy, wherefore art thou?

Roddy is in Sherwood shooting the Regionals today. I should have been standing right beside him but Life got in the way. Crying or Very sad

On my RO, I removed the disconnector and VERY lightly sanded and polished it around the tip where it fits through the frame.  I used the same fine sandpaper rolled up tightly to make a couple of passes through the hole in the frame.  No re-shaping, just to deburr and smooth out any roughness.  

I also discovered a rather nasty burr on the disconnector paddle that was scratching the trigger frame, so those areas were honed flat as well. 

I also filed a long bevel on the front facing side of the disconnector near the squarish cutout area.  I remember reading there can be issues of the disconnector protruding into the magazine well and hitting the magazine.  Mine protruded slightly, so I filed it lightly.  I wonder if you have checked to see if your problem occurs only with a magazine in the pistol.  You can see this angle cut on aftermarket disconnectors, but not the stock RO.

Lastly, I slightly honed/polished the disconnector and radiused/polished the spring where they contact each other on the disco.

This simple set of touch-ups fixed my disconnector issues.

I am not sure if yours is just in need of touching up or something more serious.  My disconnector action was a bit gritty and rough, but it did not a have any type of hard bind in it.

The RO has decent trigger for a production gun, with the application of some knowledge, skills, and tools (a Brownell's catalog and VISA), the stock trigger group parts can be tuned up with decent results.  I even managed to get a "That's a nice trigger job.  You did that?" Smile

I am smart enough to hand it over to the experts at a certain point as well.  The more I learn, the more I realize  I don't know and choose safety over savings, to my wife's dismay and KC Crawford's benefit.
