All this talk about fixing the trigger has got me working on one of mine.

Every so often my No.4 Mk.1T would "single-stage" and so today I took a look at the trigger guard fixing. Sure enough with the front screw tight I got a single stage practically every time. Loosen it off and it goes back to the correct operation.

Now before I take it all to bits and do the counting the turns on the front trigger guard screw exercise, the symptoms look to me as though the bush is too short rather than too long. So finally to my question: if the bush is too long, it is OK to shim it out by the judicious use of washers?

I know that I should really fit a new bush and adjust it properly but, like our Marine friend, I'd like to save some time (procuring one) and money.
