Just a quick heads up i went into a local maoplins yesterday for non shooting reasons. Whilst mooching i came across a large impact resistant case. It is superb for 50 quid reduced to 40! It is sold as waterproof but has a purge valve so must be airtight as well.inside its about 5 inch thick and has a thick and thin layer of pyramid foam as well as 2 layers of normal foam which have precut blocks to pull out. It will hold 4 cp99 size pustols plus some gas and pellets etc. Perfect for us!!!!!!!!!!
