minimag classic double shooting

[ldemiliani]

Hi,

i have troubles with my minimag.
it is double shooting, that is, one shot when pulling the trigger, and another when releasing.

i have checked the on off assembly, for double activations, and it works fine. no leaking down the barrel and no laqn sprinkler. i have modified the length of the trigger rod to shrten the gap between the trigger and the tip of the rod, to see if probably the sear wasn't depresseing completely the on off assembly, but it didn't work
perhaps a wrong choice of PT spacer is the cause of this?
i have been told that a worn or bad bolt spring can also be causing this.

let me know what you think,

thanks.

Is it possible that the sear is worn enough to allow the bolt to slip past it a second time?

Check for bolt and sear wear.

yep, i also tought of that, but is it is almost new (6 months use) i didn't give serious tought to it.
i will try though, since everything else has failed.
another thing, have you seen new level 7 valves working without PT spacers?
i remember once seeing one without it. i will take mine off and see if it works.
