Have now removed the cheepo spring washer from the trigger pin and shimmed the free play out with plastic shims. Polished the sear and trigger contact points and changed the spring with a lighter one of the same size and hey ho, now have a much improved trigger. (80 per cent better.) Probably not as good as the after market units but acceptible and cost me nowt. If anyone is doing theirs watch out for the tiny ball and spring that run on the safety on/off bar, fiddly bloody thing when it falls out!!! If you fit a lighter spring make sure its still strong enough to hold the seer in place when loaded. You dont want it going off willy nilly when not expected! Tim
