Advice on improving the trigger for my P2000SK .40 DA/SA by replacing the hammer spring with Wolff Hammer Spring HK USP Full Size and Compact 12 lb Reduced Power. Will it fit? Any improvement?

I also have a USPC DA/SA .45, any improvement for this one changing the spring.

The USP/C hammer spring is longer than the P2KSK spring so likely you will gain nothing and might even run into reliability problems since you might be over compressing the spring and may even bottom out.

I'm far from an expert, but those were my initial thoughts on this as well. Why in the world would the spring for a compact sized pistol fit into a sub-compact sized one?
