Not really, the 1377 is a knock open valve, not a blow off valve - such as the one in the Sharp Innova - so it doesn't put any extra strain on the trigger when you sort the power out.
Some people put a heavier hammer spring in which does spoil the trigger, but since the standard hammer spring is strong enough to dump all the air in one go there is no need whatsoever to do it.
I did a thread on here a few years ago on how to restore the new Gen III guns to their proper power potential - basically it just involves blocking a bleed hole and taking the TP out slightly and that's it. No need for flat top pistons, hammer springs or any other nonsense.
