I have a mark 2 Premier in 1.77 calibre. It's in mint condition and has had very little use. The only issue I have is that the trigger edges are sharp which makes it uncomfortable to shoot. I could easily fit my Beeman trigger shoe but I like to keep it on my Webley Vulcan. Has anyone else got a Premier with a trigger with sharp edges? Always best to remove the trigger to work on it but I guess it could be improved with it in situ and using fine sand paper to smooth the edges. However, would this cause corrosion?
