Seen a few webleys with filed foresights.
My Webley mk 1 does not shoot where I aim, and the sight is only adjustable for elevation.
What is the accepted method of windage adjustment on these pistols? Barrel bending?

Good deals with these members
Hello,
Certainly not barrel bending. A limited amount of windage adjustment is possible by enlarging or elongating the rear sight blade retaining screw slot with a small round needle file sufficiently to provide some lateral movement in the direction required. Reproduction blades are readily available should you not want to modify an original item. Remember to move the rear sight blade in the direction you want the group to go.

PS Ignore the daft comments from those such as I.J. below who will never appreciate these fine examples of British engineering.

Generally, I aim off. It's quite a nice skill to explore.
Nod to the Wobbly-haters: if I want real precision, I tend to use a pistol with a better, adjustable, rear sight.
Gentle sight filing is good. (Patronisingly, echoing my (awful, hated) technical education teacher at school, never forget that that you can remove metal, but not put it back on.)
Have you tried different pellets? Different ammo can shoot to different places horizontally, not just vertically.
Aiming off, could be OK, but its not for me... Different pellets have been tried, and they don't change point of impact enough.
I'm still leaning towards gentle bending, as that is reversible, which filing is not.
The barrel is already bent from aggressive cocking by previous owners, so its needs some bending anyway.
Hmm.
Getting a separate blade is perhaps the best option, anyone have an idea where they can be sourced?
Hi,
Further bending the barrel will only destroy the accuracy of the pistol. Like you, I'm not q big fan of aiming off, so I would gently straighten the barrel and then ensure that I could achieve reasonable groups at your chosen range before determining the direction and extent of any sight adjustments.
Replacement rear sight blades sometimes appear on that well known internet auction site or can be sourced from any of the three suppliers listed below in the UK.

If you do decide to purchase a replacement rear sight blade, make sure you specify the exact model ie pre or post war.

Is the trigger pull heavy? this can produce a marked lateral innacuracy.......

The barrel crown can also significanlty affect POI..
how far out is your gun shooting ? Also what is the power output ?
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
Mr Gen is absolutely correct with his reference to a hard trigger possibly being the problem as It's very easy to pull shots off to one side if this is the case. I's important to ensure that the trigger blade is moved directly to the rear with consistent pressure until the shot breaks followed by the holding of the pistol on aim for a further 2 -3 secs (follow through)
Iv'e found that correct attention to follow through has provided the biggest contribution to accuracy especially when shooting spring powered air pistols with the bonus of being easy to learn as you need only remember to keep the pistol on aim for a few seconds after the shot is released.

Wouldn't be hard to make another rear sight with the extra slot if you've got a hacksaw and a file
Not trying to start a debate, but I have to disagree, barrel bending has to be extreme before it affects accuracy ;-)
The gun is grouping quite okay for a spring air pistol as it is, with a slight upwards bend.
Thanks for the links to parts suppliers!
It has a fairly good trigger for a spring pistol.
And I'm fairly certain its not me jerking the trigger ;-)
Should perhaps put it over the chrono again, I have forgotten how fast it shoots. But it has a fresh spring and piston seal, thanks to a very generous member on here, and I have been satisfied with its performance after the spring and seal change.
It shoots about 6-7cm to the left at 10 meters if I remember correctly.
How come I didn't think of that myself??? Must be cause I am lazy. But that seems like the best suggestion so far!
