I'm still reading up in my spare time, but I've caught passing mention of safety concerns regarding these revolvers, but no mention of SPECIFIC concerns. Any help there would definitely be appreciated.
The only safety concerns I know of are not with the No. 2 Mk. 1 or No. 2 Mk. 1*, but rather with the No. 2 Mk. 1**. The Mk. 1** was introduced in 1942 as a wartime expediency and was basically a Mk. 1* which was further simplified by omitting the hammer stop. This means that were the gun dropped on the hammer while fully loaded with six rounds, there is a possibility that it could accidentally fire. After the war, the vast majority of Mk. 1** revolvers were recalled and retrofitted to the safer Mk. 1* configuration.
