Webley omega triggers

[mrgeoff]

I have a pair of webley omega.
They have 2 different thickness of trigger blades, and each has a different pull weight, due to the geometry of the adjustment screw in the blade.

Is this intentional, or just batch variation?


Thanks!

Ps, anyone want to swap a LH omega stock, for one of my RH?

Bought my Omega new when they first came out, sometime not much later they produced a new trigger blade and the "Darning Needle" spring guide to replace the metal guide which the very early guns where fitted with, bought both and retro fitted them

Not sure about the thickness I understood it was the let off angle that changed.

I am also tearing my hair out with an Omega trigger. Its an English version having the name etc ''rolled'' into the metal, not transfers as per foreign made versions.
It had been ''tuned'' and the trigger is so light it borders on dangerous. I have replaced the mangled wire trigger spring with a factory one. The rocker arm and front sear and its spring all seem ok. However the trigger has a hole drilled in it and a tiny coil spring fitted into it at the foremost point where the rear sear lower leg reaches out over the trigger. The trigger adjusting screw has been cut off so that it no longer protrudes beyond the trigger and so is doing nothing. Thanks to members info on here, I've managed to fit a correct length adjusting screw, this gives a two stage trigger with the little spring, but the actual let off pressure and travel is so light and tiny the gun will self discharge if the barrel is closed a little too harshly. Can anyone confirm if the trigger should have the little coil spring fitted [ its not on any parts diagram anywhere], without this spring the trigger only sits rearwards by virtue of its own spring and the safety catch won't operate. If I remove the little spring, should I get a two stage trigger by virtue of the trigger adj. screws contact with the rear sear??. Does any one have any idea as to how much the actual contact face that the front sear sits on, protrudes in front of the upper [vertical] face that end of the front sear stops against. Complicated and awkward descriptions, sorry its not the easiest of conditions to describe. I'd really like to have the gun working safely, but detailed info seems pretty sparse, parts are available, but costly. I'm thinking the ''tuner'' has maybe reduced the overlap of sears by removing metal from the contact face on the rear sear and added the spring and cut down the adj. screw to give a different trigger action. ??
Any help greatly appreciated, and a thanks for help already given.

Trouble is that there aren't enough Omega triggers around for there to be a pool of experts, and I'm certainly not one. I've never dismantled mine as there are no clear instructions on re-assembly available - I'll do it one day, but only when necessary.

I'll use Chambers part numbers. If you think that the primary (SR018) and secondary(SR020) sears look OK and unmolested, that's good. If they've been ground, filed or even polished, possibly bad. A photo of your trigger blade would be very helpful - there's no coil spring involved in it anywhere. If someone's played about with the trigger blade, get rid of it quick and just replace the whole thing. Since the trigger blade is made from a sort of pot-metal alloy, it will have no bearing surfaces other than the head of the adjuster screw, so don't underestimate the importance of the screw - it's an integral part of the trigger, rather than just an adjuster.

I wouldn't really call the Omega trigger two stage, to me it has no discernible stages - tbh I don't like it much, it's smooth and consistent, but vague. There's nothing that lets you know it's about to fire.

As before, any photos you can post will help solve this.

Ok, thanks. The bigger trigger is on the slightly earlier model with the steel tube spring guide.

They must have done some improvements on the slightly later omega, improving its feel and lowering its weight

Cheers!

There were definitely two versions of the trigger.

They are mentioned in Chris Thrales’ book, where he says that the Eclipse u/l (introduced in 1988) used the “perfected unit as had been used on later versions of the Omega”. Which suggests that the later trigger came in no later than 1988 (Omegas were made 1984-1994).

As I recall the modified trigger was available, direct from Webley,around a year after the rifle was introduced, I believe the "Nylon Darning Needle" spring guide should have been fitted from the start but a steel guide was fitted due to supply problems.
I had a clear out a few years back and give the purchase paper work from Webley to Chris Thrale otherwise I would have been able to confirm dates.

Still have and shoot my Omega very nice gun

Well done - with you and Donald, we now have two experts

[thisisdonald]

Lol.. no expert here mate, but I appreciate the sentiment! I'm just a tinkerer like most, but learned a long time ago to take photys!
Glad you got it back together and working safely.

[abellringer]

Thanks but like Donald, not really an expert, just a nosy enthusiast haha; but I do like to keep guns and shooters going as much and as long as possible. Have to say this forum is great for doing just that, always people willing to help, advice for one person often benefits many others and I'm glad I'm part of that.
Again I have to say many thanks for the help given, gun now working fine, parts a bit pricey though, but you can't do without them.
If anyone needs help on this trigger I think we have sorted most of the problems and the one I had was certainly not standard, but as this was my first Omega, I was certainly confused by the layout and it just goes to show not all tuned guns are better than standard ones; and I have to say it's a bit worrying that a supposedly improved gun was in fact so dangerous. Also it showed up several variations of trigger assy's. which is always a help to first time service / repair enthusiasts.
Big pat on the back guys.
So have a Merry Xmas and Good New Year everyone; and lets continue 2019 as we end 2018
