I installed a D spring I bought from Beretta #EU00043 in my 92fs. On the website it is listed as a part for the 92, Cougar and PX4. The resulting trigger pull is very light (or maybe just compared to a standard 92). I know that’s the desired result but the pistol is ccw use so reliable ignition is my primary concern. Is this the correct part ie the spring found in M9A3s and Brig Tacs?
