Right so afther a fair few years off shooting I gave in to my childish niggles and bought myself a walther cp88, and on its second outing in my super giddyness on the 6th or 7 mag refill I noticed the rear sight had fallen off! (dont ask my how I never noticed unless it fell off as I put it down) so I decided that that was enough for the day and went on the search for the sight, it didnt turn up but I did find it a few weeks later on the floor and wondering what it was decided it was rubbish I then chucked it in the bin! now I have twigged it was my missing sight and I had binned it

So does anyone know if I can get another or a better one or I have seen a fair bit about red dot sights which sound funky but are they worth it for a back garden fun gunner?
