Seized firearms and their ballistic ratings in London since 2020

Freedom of information request reference no: 01.FOI.24.041148

I note you seek access to the following information:

Please provide details on the most common type of firearm and its ballistic rating for seized firearms in London since 2020- please also include blank firing weapons that have been converted.

CLARIFICATION -
My question regarding the firearm relates to a real firearm or a converted blank firing weapon such as a Readily Convertible Imitation Firearm and not a gas or air powered device

Ballistic rating in my question refers to the calibre of bullet, shot or other missile discharged (or could potentially be discharged in the case of a readily converted imitation firearm) from the most common type of firearm

Further reference can be found here in Page 8 Section 1 for your reference to Ballistics, Calibre, firearms etc
