trigger sumps and 4" klir

[natgun1]

anyone have any ideas on how to modify a trigger 34 sump to fit one of these klir filters. with only a 3 3/8" opening above there oval filter sock hole feeling a little left out.

From looking, I think even widening the opening wont work, as the filter chamber is only 4" across.

Filter chamber in my Trugger Emerald 39 is 4.75 inches.
