Great product, ambiguous description - Heckler & Koch VP9 Long Slide Optics Ready Complete Slide Kit

My slide kit arrived today in the original HK box. It's HK, so of course it's a quality product. The ordering process was straightforward, the price was fair, and the free shipping was within the 5-10 day predicted timeframe (with a faster paid option available if desired). I'm dropping a star for two reasons: 1) The description on the website is ambiguous. The HK box is labeled "Kit, Slide Conversion, VP9L OR, Comp" but the website calls it "HK VP9 Optic Ready Slide Black Steel With Tall Sights and Cover." While the photo shows the full kit (slide, cover, barrel, and recoil spring) nowhere in the. description is it stated clearly that this is indeed the full kit. That matters because at least one other vendor is breaking these up and selling the individual components. I ordered based on an an acquaintance assuring me that he received the full kit but a little more clarity would be nice. There's also one minor mistake, the slide cut is HK's standard optics mount which takes any of a series of adapter plates; it's not a "RMR mount" as stated in the description, the RMR mount is plate #2 and ordered separately. The only optic that currently mounts without a plate is the Holosun SCS-VP9. Finally, 2) as someone who lives in a PO Box town, I really wish everyone would be clear early in the ordering process about shipping methods, I need to enter the shipping address slightly differently depending whether it's ground carrier or USPS. I literally didn't know whether this would hit my front porch or my mailbox til it arrived this morning. These are all minor quibbles thus I'm still giving it four stars. Please take these comments as suggestions to make a generally good process even better.
