Permanently attached mod on LBP legality

[TattooedGun]

If one were to buy a long barrelled pistol, then get a RFD with sufficient skill and license (if necessary) to shorten the barrel and permanently attach a moderator to it to get it to the 300mm minimum length. Would it be legal?
What are the options of attachment in this situation? Welding? Pins? Screws? What constitutes permanent attachment?

Just curious...

Difficult part is attaching the mod before the barrel is cut down under 12" which will make it "Once S5 always S5"

Lantac have done similar with their Sub Raven.

Disassamble the gun, so it is always an S.1 gun undergoing "maintenance" - same as stripping down a 12" barrel 10/22, a gun which is much shorter than 600mm without the stock.

Blind headed pins/adhesive and welding only - anything that doesn't need a hacksaw/angle grinder to remove will be deemed as removable.

Could there be a problem with the fact that the mod is not rifled?

It's been done with Buckmark LBPs, just trying to find pictures.

IIRC a court case about back boring pistol barrels to create an integral moderator was won by the defendant. I think I read the details on the Jackson rifles website - I'll check when I get the chance.

Edit (2): The Court case was in regarding back boring a 10/22 rifle and if it should have gone back for proofing. The case was abandoned after technical evidence was submitted - http://www.reflexsuppressors.co.uk/ last paragrapgh

There is no issue with the lack of rifling in the 'barrel' the important part is that is is not less than 300,0mm from bolt face to end of barrel. To permanently attach I would suggest screwed and silver soldered would suffice as would welding, screwing and gluing might not be quite as effective as the moderator body could be removed with a heat gun, then again it could also be removed with a hacksaw...

In theory to keep completely within the law you would need to take a barrel blank, permanently attach a moderator to one end and then thread it to fit the firearm which might prove to be a PITA. There is an obvious alternative...

If I recall the K22 comes with an optional integral suppressor, believe Caledonia call it the K22 Whisper

Ahh, thanks for the advice guys...

Late night, "cant sleep" thread for the win!

Okay, so we can get permanently suppressed LBP's... we can have revolvers in pistol calibres....

What about a permanently suppressed 1911 in .45 ACP with some sort of single round magazine so it can only be fired single-shot...?

I know people can have modified glock magazines on humane dispatch Glocks that then become single shot... what about us Section 1 folk...?

It would be legal the only problem is deactivating the blowback. I think the only solution would be to interrupt the cycle like the SGC 9LR, but in a 911 format. I believe someone is developing lever release LBP in 9mm and .45 but I haven't heard anything in maybe a year.

Yes but it's a 12" barrel that is ported/drilled.

Will not be nearly as effective as a pistol length (4"-5") barrel with suppressor which will keep the velocity down.
