Members should note the following clarification received from the Home Office 

"The .320 British (also known as the .320 revolver C.F., short or long) (W&M) is listed in Appendix 5 of the Home Office guidance.  However, the .32 Short Colt is not listed and should not be considered as an obsolete calibre"

Any member with a doubt about a specific item should contact a section 5 dealer for urgent advice and clarification"
