^^^ What ssb said.
The Keeper was a front runner in the ability to make minor tweaks and adjustments for preferred position. I think originally that likely justified a lot of the price, but with the rise in features of the other manufacturers the keeper may be falling behind.
I don't think the sight coverage thing is necessarily a fair docking in general as the item is a full custom so the customer ordering would specify the sights or size of the guard. Though it is an important thing to note for secondary market purchases for sure.
