Update! Phase 2: trigger & spring kit installed
Well....the parts arrived and so we got the show on the road.
Contenders installed in phase 2 of the upgrade: Trigger spring kit from Wesbaun as suggested, and the Boudica trigger from Galloway Precision.
This may sound shallow/superficial, but the Boudica trigger looks the business more than the DA revolver-style shaped OEM unit; it slightly redeems the SW40VE from ugly status; and at first after the install & reassembly in checking functionality I was rather ambivalent with the initial results perceived. Yes it mitigated the over-travel and lessened pre-travel....but...well....was hoping for more. Seemed to get a bit better after 10 cycles. So I slept on it, and then performed some repetitive cycling over the next few days. Somewhere around the 30th cycling things started getting interesting.
I'm happy to report that since a number of cycles with the upgraded pieces (oh I'd say 40 or so) using snap caps; it has improved tremendously. I've no scale so I'm guessing it's in the 5-6+ pound range. IMO it's likely perfect for its intended use as a nightstand/property/truck implement.
There is zero compromise in safety, IMO from the OEM trigger. The welcome decrease in pre-travel is not only noticeable, but the pull is pretty smooth..... now the trigger firms up just a bit after the initial say 1-2 mm of pull and pulls smooth all the way through the break, and stops just afterwards with NO over-travel. Reset is gently tactile with a slightly perceived audible 'tick'. The trigger will likely improve a bit more with more use.
The SW40VE is my first striker-fired sidearm, and perhaps not my last. Admittedly a luddite, I'm somewhat warming up to what's possible with these.
Thank you for the collective advice here, as I believe this has made the most out of this sidearm. No it will never have say, a SA XD-M Elite (or better) trigger, but I'm a happy camper for what I have invested in this little project. Now I need to get out and shoot this thing and put the snap caps away.
