i can get a p30 for about 1016 with no night sights with a frame that wont rust . or i can get a sig p229 nitron finish with night sights for 832.
i hear you have to grease the daylights out of the sig to make sure it functions properly and that just a few drops will take care of the hk. so if someone could tell me that has dealt with either of these guns the truth about these issues that would be great. i also heard that the sigs will get surface rust fairly easy. i just hate to spend 184 more dollars and then still have to buy night sights to go on the hk which will be another hundred bucks. advice needed. thank you all

I have a similar setup of what you're considering with a P2000 (the P2000 was the precursor to the P30), and a P229ST (stainless steel frame).

Your P229 under consideration has an aluminum alloy frame and stainless steel slide, so those components should not have rust issues. Sig rails need more lubrication than the HK.

Sigs need lube, but heavy amounts of grease will make it less reliable, not more.
I treat my Sigs like any other full length rail gun (1911, BHP, CZ...), a light coat of light grease on the rails is plenty. I paint (short, stiff artist brush) Slide Glide Lite on the rails so thin you can't see the color of it, that's plenty.
Oil is fine too with Sigs, you just have to replace it more often.
I've had two failure over the years with Sigs, one I took a used German P226 that I just bought to the range and had a few failures to feed from the slide short stroking. the gun had no lube, probably from sitting on the dealer's shelf so long. After proper cleaning and lubing, I never had another problem with that gun.
The other was with a different P226 where I used heavy lithium grease from the hardware store and applied it too heavily. Too much, too heavy.
Both failures were in very cold weather, probably a contributing factor.
I've never owned a P30, but all the USP's I've owned were lightly oiled and never had a failure of any kind.
