Hey all. I've got a P2000 in .357 Sig that also has a 40 barrel. I've noticed that a certain part of the lockup on the guide rod is wearing sort of in a nasty way. The barrel is perfect, nothing on the barrel wearing on the guide rod. I feel like I need to replace the guide rod to prevent wear on the barrel, even though the round count is only a couple hundred rounds.
I understand that the .357 Sig and 40 are pretty powerful cartridges but I still feel like it's sorta premature. It's either normal, or premature.
Has anyone else seem wear like this?
No. That wear pattern doesn't look right at all. I have a P2000 I use with a .357sig conversion barrel. 1500 rounds in .357sig and 500 rounds in the .40. The finish is only worn in that area (no material wear like yours).
That looks almost like it was rubbed on asphalt. Or rubbed on concrete. That is very strange! All my HK pistols have a very smooth wear to the guide rod, only a little of the finish is gone in the area of the picture you attached.
Sounds like I probably need to replace the guide rod before shooting it anymore then huh? I don't want to damage the barrels. I have over half a dozen HK pistols and this is the only one showing this wear, and it has one of the fewest round counts.

There are other same posts on this, P30 IIRC.
My P2000/9 just hit 700 yesterday, and just the finish (not metal) on that lug is wearing. The same with my other HK’s, finish yes but have no metal wearing on the lug either.
At 200 rds shoot it some more, it could be normal. A pistol action is the sum of all parts, a ballet of mating parts each with its own tolerance – tolerance stacking. There’s no wear on the barrel because it’s harder, as an HK should be.
Lube at that point… it’s gone/diminished at the first slide cycle.
Consult with HK first, then post back their response.
