I think this beetle is a Pterostichus, but there are a few which look much the same.

Pterostichus melanarius I found on a site in the UK, thinking good, got it.

Looking at the other look-alikes I can eliminate some maybe because of the basic body colour, some being more brownish black or matt black, but there are still some it could be. It's quite a large beetle, the violet glow doesn't necessarily place it as Carabus violaceus purpurascens, the colour on that looks to be on the edges assuming that is a true likeness.

Any ideas?
