Jericho 941FS shooting WAY high

[hq]

I've had the pistol in question for a few years and shot it occasionally. I've known the sights are off vertically, ie. the rear sight is much too high and they're fixed so there's nothing that can be done about it short of filing it down. Which is quite impractical considering the luminous dots on it. Today I finally analyzed it properly and yes, it shoots no less than 4" high at 10 yards and 10" at 25 yards.

Unacceptable.

I'm not really a fan of Meprolight sights except on carry guns, which the Jericho rarely is for me, and even though adjustability would be a (minor) plus, I'd prefer low profile fixed sights. Considerably lower than the current high front / even higher rear on the gun. Are there any ready made solutions available?

Use the Brownell's Sight Correction Calculator to determine how much one of the sights must be changed.

it seems you really want LOW PROFILE sights, why not just install a non-tritium REAR SIGHT which is lower (and much less expensive). Brownells can probably help there, too. In many light conditions, just seeing the front dot is what's really critical.

+1 on the Brownell's calculator.

Thanks for the link. I already had calculated it manually, coming up with a figure of 1.35mm (.053") lower rear sight. Or ideally a complete, ready to fit matching pair that's close enough to actual POI. To illustrate the issue, here's a picture of my Jericho - the sights look (and are) ridiculously mismatched, accentuated by the semi-compact short slide. I got it from a police auction so there's no warranty or return policy even if I had noticed the magnitude of the problem earlier.

I already checked Brownell's and they have nothing to offer. Neither do most major US and international retailers and ordering directly from Meprolight Israel is the only option I've found so far. Slightly more target oriented sights would be preferable.

If you can't do it -- I know I couldn't get the specs right -- you can have a gunsmith measure the dovetail of the rear sight.

Once you have the measurements, I'm pretty sure Brownells will have something that will work (based on measurements, not the 941 designation.) They have literally hundreds of different sights in their catalog. I'm know that is the case with non-Tritium sights, but it may be possible with tritium sights, too.

That rear sight really does look like a step ladder!

What if you turn the rear sight around and reinstall. You could file it down with out worrying about the dots because they are facing forward. Here is a good way to file down the rear sight. Take a piece of glass say 1 foot by 1 foot. Tape some emory cloth to the glass. Now turn the gun upside down and plane the rear sight on the emory cloth while the front sight is just on the glass. You take off a little at a time and it will remove metal cleanly from the sight. It will .come out square this way. Just scrape the paint out of the dots and cold blue.

The sights are night sights. That's why I suggested getting a non-Tritium rear sight from Brownells. A tritium front sight may be enough.

 

[railroader]

Walt he said they were luminous dots so I assumed they were painted like CZ sights that glow from charging the paint with light. Maybe a witness sight is the same dovetail cut. and he could find a shorter sight. Since the OP is from Finland I'm not sure what his options are for parts.

 

[Walt Sherrill]

I never saw anyone do luminous dots except CZ, and those light sensitive dots, to borrow a phrase from V.P. "Cactus" Jack Garner, are "not worth a bucket of warm pi$$." (They only work for a while, when CHARGED, and to charge them you can screw up your own night vision.)

I, perhaps incorrectly, interpreted the OP's comments about Meprolights to mean they were installed (apparently inproperly) on his 941. There are a lot of images of Jericho 941s on the 'net, and while all of them seem to have really HIGH rear sights, the ones in the OP's photos above seem UNUSUALLY TALL Examples. See what I mean? :

What you recommend would work, but would really still make the gun look like it was walking around in very high heels.

The original poster could also just DEEPEN the notch at the rear and paint over the dots (luminous or tritium) and stop there. (If they're not tritium, he could, after deepening the notch, grind away on the top of the rear sight, too.)

If the gun were mine, I'd push out the rear sight, measure the dovetail (by measuring the sight's base rather than messing with trying to measure the dovetail, measure the angle, etc.) and contact Brownells -- and get a new rear sight that was a bit lower. (The OP knows how much lower it needs to be.)


If the original poster hasn't really done the full calculations which takes into consideration the distance to the target and sight radius. Doing the actual calculations based on where the bullets are hitting is really a good thing. But he'd need to shoot from a rest (bag of rice, etc., with hands resting on the bag while slowly pulling the trigger.

MidwayUSA has a great parts catalog, too... and he might try contacting MidwayUSA, too.

(Having a gunsmith do all of this would take longer, but there's be no problem with doing it wrong on the OP's dollar.)

So... to sum up this, modifying the original rear sight might be an option but considering that it would mean grinding it down more than two thirds of the notch depth (!!!) and having to file/machine what essentially is a new notch, it doesn't sound tempting. A generic replacement rear sight sounds like a good idea; according to factory specs the dovetail is supposed to be 9.50mm (.374") but I measured it at 8.65mm (.340") so I'm a bit confused. New Jericho has a 12.0mm dovetail. Maybe I'll just hand it over to my gunsmith and let him sort it out.

From what I have read supposedly the older jericho has the same sight cut as a witness pistol. How tall is the sight in your gun? I have a witness rear sight that is .340" wide at the base and .362" tall that I'm not using. Here is what the sight looks like. http://smg.photobucket.com/user/larryf1952/media/Guns and Targets/EAAWitness.jpg.html
