I headed out late so I only managed to visit three gun stores, one in Vernon, two in Kelowna.
DEL SELIN
Very busy and crowded. I was helped by a gentleman called Ed, who showed me several rifles and guns. Their selection is excellent. Pricing is fair. Ed was very nice and welcoming, other employees in the store seemed slightly more curt towards their customers, but nothing unacceptable. They were very busy, but Ed managed to spend 45 minutes showing me firearms. Of course I was upfront that a sale wouldn't happen today and invited him to serve customers anytime a new one would approach the counter. My impression was good and I will definitely shop there in the future. I'm not a fan of how crowded it was, but it's a price to pay for the selection available. Definitely my favorite selection wise.
WEBER & MAKIN
I was the only customer here and was able to spend a good half an hour handling rifles and handguns. Chris (Weber) was very friendly, knowledgeable, and welcoming despite my lack of RPAL. The selection is OK, obviously not as good as Del Selin. But it's a clean little shop that doesn't make you feel crowded. It's also way less busy so the shopping experience feels a lot more relaxed and less rushed. Price wise, I'm not sure how it compares to Del Selin, but I have seen decent prices on a couple of items for which I knew the street price. I was offered to buy and have the items held by them until a valid PAL is produced. My favorite from a customer service standpoint.
GROUSE RIVER
Surprisingly, even Grouse River, a big outdoor store, let me handle a few firearms without RPAL. The guy at the counter was nice and didn't mind my predicament. He also offered the possibility of buying and then collecting once the PAL arrives. Prices are on the higher end side but they also have some firearms that neither of the other two had in stock (e.g., Browning Buckmark). The interaction was a lot shorter than the other two stores and there was a lot less of "hey check this one out" volunteering by the clerk. That said, they had some nice used items and I have no complaints. Should I want a firearm that they have in stock, I won't have a problem buying it here.
So to answer my own question, window shopping seems to be OK in my area.
