SRT install: New hammer not required, apparently. What would you polish, while it's apart?

Hey all-

I am helping my neighbor install a Short Reset Trigger kit into his stainless slide .40 cal P226. I have the Sig Armorer DVD and basic armorer skills.
My question is: A new hammer may not be required but how recommended is it? What should we inspect to decide if it is warranted? If it is warranted, will a good condition used hammer be okay or should we just go straight to a brand new one?

Thanks in advance for the advice.

Edit: No new hammer. Got it.
What surfaces are safe to polish for a smoother trigger pull? I will be using Q-tips and Jewelers rouge so I don't alter any geometry between engagement surfaces. I just want to make things slick before lubing and reassembling.

It is probably not essential, but many here may recommend it. Round count is a consideration. There was a recent post where I recommened the OP install a new hammer with the SRT sear because the gun was 30 years old.

Can't think of a reason you'd need to unless there is physical damage or excessive wear.

If replacing the hammer is the way to go, be sure to check for variations made during production so you would be sure to get the same style hammer that came off if it.

This line of thinking is based on some assumptions, and therefore risky, but I must believe that if replacing the hammer along with the SRT kit was important for any significant reason, including safety, the hammer would be provided, or at least there would be prominent warnings about the need to do so.

The traditional advice was to replace both hammer and sear of DA/SA guns at the same time if one was changed, but the reason for even that was never clear to me. And even having pondered the question for years, no good explanation has ever occurred to me.

If you don't own it already, I would highly recommend picking up this DVD set: https://opspectraining.com/pro...auer-armorers-video/

It's been a while since I last watched it, so I can't give you a direct answer from memory, but among many, many other things in the video, Bruce goes over where it makes sense to polish components and where to leave them alone. It's a great resource all around!

Because the engagement surfaces of the hammer and sear have "worn in" together over time?
