Umarex SA10 at 3000-3500 rounds

I've kept all the used cartridges to estimate total shots fired, I'm at 50 so 3000-3200 rounds.
I'm using a small drop of silicone oil on the cartridge, silicone grease for the slide, and a gun cloth for the exterior cleaning.

I've used cyanoacrylate to fix a small plastic corner of the barrel mount some months ago.

Anything else I should do to keep care of that pistol? Gun seems fine, at least I hope to use it for long...
