The stripped slide goes for $260 on their web site ($170 for a similar slide at Lone Wolf, but this one is advertised as being much more better

). It is not relieved for the red dot sight they use and still bare stainless.
The red dot model they use goes for $604 on their site.
A stainless threaded barrel with thread protector, both black oxide treated, at Lone Wolf is $155.
Lightning Strike Titanium striker and striker safety from Lone Wolf along with other misc. slide parts, $250.
Relieve slide for red dot.... $100?
Cerecote slide $150?

So, that price is not out of reason, if that is something you want. Also, from the advertisement, I suspect the parts I listed might be of lesser quality than those hyped in the ad.
