All very interesting and helpful.

Those Williams peep sights look superb but, I fear, are not available in the UK excepting at high prices.

Personally, I find shooting with peep sights (diopters included) is much more rewarding than with ordinary open sights or telescopic sights. I am potentially looking for something for my Walther LGV.

What do others experience with regard to recoil creep? Is this a problem, I wonder?
