I have tried everywhere else including Midway and Ithaca with no success so I thought I would put this out here. I am looking for a Modified and an Improved Cylinder choke tube for a 20 gauge Ithaca 37 barrel made in King Ferry. I have been told that the King Ferry chokes and the current Sandusky Ohio tubes use different threads. Any help would be appreciated. Thanks.

Do you want flush tubes or extended?

Did you try these guys?

Sometimes it helps if you just call them. Pretty sure the tubes themselves are standard Tru-Loc tubes for the 20 gauge guns.

It makes no difference. I just want a Modified and an Improved Cylinder.

I tried them. They are out of stock. Closed today but I will call Monday unless I find some by then. I just picked this little 37 up yesterday practically for a song with no extra chokes other than the full in it.

If you have tighter tubes, is a latch ditch option?Could you have those honed out to meet your needs? I've never heard of it being done, but I don't see why not.

Oh wow, Perry! An Ithaca Model 37! That was my first shotgun I bought when I was 16. I still have it. It's a 20 gauge with a solid rib. I had it reblued years ago and it is a fantastic gun. It has a full choke and I always shot it very well. I got a lot of squirrels, quail and rabbits with it. You might want to try it with the full choke. It might work better than you imagine. Good luck with it. You got a great gun.

You would be removing metal on the opposite side of the choke tube threads. There isn’t much there to begin with. That doesn’t seem like a good idea.

A set of tubes will turn up. They aren’t moon rocks.

How does it end up being any different than an original IC or C choke tube? The threads are the same regardless.

I would expect the factory work would be perfect, much better results than would be possible by running a hone to remove material. The inside of choke tubes never look like they have been honed. You aren’t going to get those results with a brake hone and a 3/8ths drill.

It would still be easier to install the correct choke tubes.

If you strike out try my buddies at Comp-N-Choke in Sylvania, GA. Ask for Jake, and tell him Stan Hillis suggested you call. Jake and his wife go to church with me.

They make all their tubes right there in-house. Unless it's a very, very rare bird they will have them in stock. They're all extended style, however. Very high quality.

Thanks to all. I have never heard of honing a removable choke tube Brent and it just doesn't seem like the metal is there to prevent the hone going into the threads. Stanton, I did a search on the Comp-N-Choke site and turned up no listings at all for Ithaca chokes of any description, but I will call them on Monday. I have not yet contacted Briley but I am not aware of them furnishing choke tubes for existing factory choke borings, but I will ask. Anyway, like I believe Ted says, something will turn up. And for what I gave for this delightful little 20 gauge pump I can always keep it with the existing full choke tube for pheasant. Hey, I hunted quail for years with my Ithaca 12 gauge Deerslayer before I came back to double guns, so anything is possible!!

Oftentimes a manufacturer will use a thread system of another maker. Jake will be able to tell you if this is the case with the Ithaca you have.

If I see Jake at church this morning I'll mention it to him.

Good luck!

My Kings Ferry Ithaca’s use Winchokes, but my guns are/were 12 gauges. I ordered my extra chokes from Trulock.
I believe the kings ferry 20 gauges still used Tru-choke threads/chokes.
These are available from Trulock as well.

The Sandusky guns use invector plus threads but the bores on the Sandusky guns are not overbored like Browning inventor plus barrels.

I remember that gun! Glad you figured out what chokes it takes, I think I screwed a modified in when I got it, and never looked back.

I went to the TruLok website and found the choke tube interchange chart and the Kings Ferry guns do in fact use the Tru Lok Tru Choke standard pattern in the 20 gauge guns. Thanks for the TruLok reminder. I just placed my order for the two that I need. Thanks to all for the help.

Perfect!

Now, we need 20 pages of biting commentary on what to lube them with when you get them.

Good luck,

This has apparently been solved, but just for the record...

Briley can 'open up' any screw in choke you might send them. They did it for me on one of their VERY thin wall tubes without breaking a sweat. This was the kind that have the threaded area elongated because the tube is so thin and the threads so shallow. It's a square thread (Acme) and they need all the threads they can get for a Winchester Model 50 barrel. My tube was a IM, and I had it taken all the way out to cylinder. Easy for that shop. They charged me $40 at the time which was less than an extra tube.

Briley also sells chokes for what appears to be any and all factory makes and styles.

It's a machine shop that specializes in choke tubes and I just bet they could make you anything you can draw or duplicate anything you send them.

CompNChoke makes and sells tubes as open as -.005". That's negative five thousandths, meaning that it is five thousandths more open than true cylinder. They're thin, and can be damaged by a fall or a hard lick, but if someone wants one they're available.

Beretta tubes marked 'skeet' have been like that at least since 1997 when I bought my first Beretta with 'Mobil Chokes'. They measure about 5 thou over bore. Those tubes are threaded on the muzzle end too for whatever reason, and they had problems early on with steel shot expanding the choked area into the threads making the tubes near impossible to remove. I broke a Brownell's stuck choke tool removing a M and a IM from an early 686 after the owner had fired a few hundred rounds of steel. The thread damage was limited to the last couple threads so the barrels were still serviceable. Beretta changed to a tougher stainless for their tubes and the steel approved ones are now marked 'SP'.

Brownell's refunded the tool. They made no comment, but I would have liked to have heard what they said when they got the thing back.

My Briley thin wall, steel proofed tubes are a different shade of grey than the stainless tighter chokes. I have wondered if they might be titanium. They must be 30 yrs old now, or more.

If you leave the choke tube in long enough, and fire enough rounds through it, it eventually becomes a fixed choke.

Thanks SGJ. I have learned something today. I was not aware that Briley sold chokes like you say. I only thought they threaded barrels and inserted their tubes in them. Anyway, I have a couple of TruChokes on the way so I seem to be fixed now for this little pump gun. Thanks to all for the assistance and the knowledge.

Titanium is significantly less dense than steel. A blind fool could easily tell the difference.

OK, nevermind... we understand your confusion.

I used EAA Baikal-Remington chokes (Trulock thread) from CDNN in my 20ga King Ferry Ultrafeatherlight. They list IC, Skeet and Modified at $3.99 each.

$3.99????? Damn!! I wish I had seen this before I ordered them from Trulok at $26.99 each.

I'd be willing to bet you will be happier with the Trulok chokes.

Nothing good sells for $3.99 anymore.

Best,
Ted

Prolly get a Pabst tall boy and a Slim Jim for that.

Actually it's a keen to buying Smjör butter at Whole Foods Market for $3.69.

Wow! You got off cheap. I paid around $125.00 last fall for a set of Briley extended skeet chokes from Joel Etchen's for my 20 gauge 687 lll. I know. I know, people. But, I could not find them anywhere else. And besides- when it comes to guns, isn't it true that money is no object? 🙂------GO HOOSIERS!!
