Holosun 507K meltin for Sig 226R

Hello, I want to put a Holosun 507 K mounted ahead and as low as possible on a 2008 Sig P226R . I want to use the supplied recoil pegs, not eliminate them or grind things down from a Shield pattern. I also see no need for a complete refinish of the slide as it is stainless . Who does fast turnaround and if I send the 507K will fit it and make sure it is close to centered ? Thank you for people who have done it and are happy.
I came very close to purchasing the Meprolite Micro RDS "bullseye" system with a new set of tritiums and the rear sight with the QD mount ramp, but have no great reviews for the Meprolight Micro red dot and don't think I can handle changing sights myself, besides a good melt is lower and on the ones I have you can barely see the factory sight on a low mount 507K so can use them in a pinch .
