Dave,

Of the five (5) Rowan Engineering Extra set-back trigger blades I have in my HW springers, none has been any more 'wobbly' than the standard HW trigger blade.

In fact, as the pin is a much closer fit in the Rowan blades, they 'wobble' less.

If needed, you can use some M2 washers either side of the blade to take up any slack.

Have fun & a good Sunday

Best regards

Russ
