The reg I used was a CP Reg, so the grip frame was off at the time of testing.
I don't think a video would pick up the audio, but I'll give it a try
I'm just getting a feeling of been let down a bit, when I first got it, the ASA had to be re-threaded as it didn't go far enough, seems like the process started early and finished early.
Then when I got it back, there was an issue with the bolt, there was a warped raised section that kept catching and splitting orings, so had to get the bolt replaced. Now there isn't really any where in the UK to get it properly looked at by a competent tech.
