MCarbo Sig 365 Flat Trigger upgrade and Spring kit issues

[Spartan]

Installed these today, the Mcarbo lighter spring kits and Mcarbo flat trigger upgrade in my 365XL.
I notice a small positive difference in the reset.
Otherwise I do not notice any difference at all.
I work in a gun store, and have been comparing a flat triggered 365 XL and the difference is negligible. Definitely not justifying the expense of the kit prices.
Am I doing something wrong?
Should I be doing something different?

I am confused... my stock 365 has an excellent trigger. Why does a 365 need an upgrade?

Because…
Mcarbo makes one…

I understand this logic.

Ive been wondering about the spring kit myself. I don't think the stock trigger is great but i also need to break it in some more.
