Bought a used P220 in 45acp recently and have two questions...

1.Main spring weight on the factory guns?
(Not sure whats in it right now, but DA seems heavier than my M11a1).

2.Sight numbers on the factory guns?
(Currently has a set of worn-out Trijicons marked "8" and "8" on it.
I thought P220's typically had a 6/8 combination coming from factory.)

Thanks for any & all input.

Above serial number 219166: 24 pounds
Cant say for certain on sight numbers.

Trijicon's site says 6 and 8. I've had a lot of P220s, have always used this combo and they've all been super accurate.
