Welcome to the (pre) Club.
I fell into mine by accident via a relationship with the factory. Went intending on a 226 Elite 9mm, but they were out, and just walking in with a stack of boxes of MK25's that were still factory warm, so.......
I l o v e it! You will too, absolutely no doubt. I got lucky again and got one with chrome barrel. The tech said expect 8000 rounds with that barrel, and reminded me I was a lucky boy to get one (twice).
This thing is dead on accurate, looks and feels like a GUN (read steel slide, aluminum lower), and the sights are just so freakin awesome. This pistol is not going anywhere and my son will get it when I'm dust.
Balistol CLP for me, tw25b grease on the rails and other rubby bits each range trip is all the babying it is going to get. This will be what my instructor who is SF's calls a "working gun". His 2022 didn't look out of the box or a safe, and looked worked in a good way if you know what I mean.
Do yourself a favor right now: order the .22LR conversion kit, 1 or 2 extra mags, and the sigpower.com mag upgrade kit. Those will likely take awhile to show at your door too. Then you'll have option to plink/practice at 7-11 cents per round vs 27-42+ per with the 9mm, and you will always have something in hand to go play.
Happy dreams (if you are not having them already) until you get it in you hands!
