I think the situation was more of a "poorly repaired components" mess.....

...but
here's the story that you might be thinking of....

...and yes

, Grant's a CGN'er !.....
Funny that story is not the Compleat story on that gun and its the only picture thats been around for years of a MKVI blowin up.
The Story i read on what really happened was the load that blew that gun up was some hot factory ammo or hot reload, i dont remember the exact round that caused that but it was some hotter than normal round.
It got in the gun by mistake.
it was only one round that was not supose to be used in the gun.
Standard factory 45 Acp is shot in MKVI webleys all the time with no problems.
Tho its good advise to reload it down some thats not whats happening in the real world.
That picture of that one blowin up gun has been around for along time.
With all the webleys shaved to 45 Acp sold up here in Canada i have not heard of one been blowin up by anyone yet.
I have a MKI** keeper, thats a MKI** with a MKV Barrel and cylinder installed by the webley factory in 1914 i shoot factory 45 acp in it all the time.
No signs of any latch screw bending even no presure problems either, easy extraction to.
The gun is as tight as new with 100s of rounds both reloads and factory thru it! so its not true at all that all factory ammo will blow up guns.
So dont let the picture of that webley blowin up scare you to much.
Its still best advise to reload down abit tho.
just remember one hot load can blow up any gun if it gets in the chamber by mistake.
I think people are carefull what there shooting in there guns up here.
Also the design of the gun or model and its strengths must be taken into account.
Some guns are just alot stronger than others. Does it have a more modern cylinder/parts ect ect
