Ruger P89 guide rod / spring assembly

[Whirlwind06]

I'm looking at replacing the guide rod and recoil spring on my well used P89. Brownells has 2 assembly's:

V22000100 780-001-107 Guide Rod/Recoil Spring Assembly

and

V02000100 780-001-055 Guide Rod/Recoil Spring Assembly, w/o Tip

Just not sure which one to get.
