Glad you liked it Bob,spares are not a problem,and I have already sourced spare breech seals from Solware.It is very unlikely for the seal to drop out and I never have had it happen,in saying that someone had messed with it without askingOne night and had managed to lose both seals.Looks I quite like the "industrial" look and the trigger is very nice(not much if any difference from many of the top end pcp pistols).it may not be the prettiest pistol out there but it does what it says on the tin to coin a phrase.
