Convert P220 DAK to SA/DA
Although the earliest P220s didn’t incorporate it, you should have a hammer reset spring.
The purpose of that spring is to pull the hammer back from contact with the firing pin if the hammer is “thumbed down” rather than lowered with the decocker. The lack of that spring was supposedly the reason a police officer was killed by his dropped P220 many years ago.

If the decocker is used as it should be, the reset spring serves no purpose and is unnecessary, but I suppose there might be some sort of liability thing if someone else used the gun and didn’t decock it properly on a chambered round.

One other thing I’ll mention about the P220 hammer reset spring is that it’s the only SIG pistol part I’ve personally seen fail more than once. For some reason they are more prone to breaking than any other part in my experience: get a couple of spares.
