Hmmm, newby on the board starts out with snarky comments and tells other members to go elsewhere. Classy way to introduce yourself. Edit - NOT!
I've never been to Rainier but have been to every where else mentioned. Quantico is large with lots of stuff and is right near Tactical Tailor for your pack and pouch needs. They don't seem very friendly if you don't look LEO or mil even if you are former or reserves. May just have been that my wife was with when we went as we were headed to Seattle. Surplus Arms and Ammo used to be right there but I believe that location is only ammo now and they moved their FFL and I have not been in their new location. The old location had a ton of ammo on Costco style racks, a fair number of firearms..this was mid panic and as they were moving shop but they always seem to have plenty. Scopes,mounts,etc but not much for holsters and zero for carriers/pouches/etc.
The Albany US Tactical shop is small with lots of office space in the back. The owner (son of owner?) is very nice and I see them at the Oregon knife show and and also stop by their shop every year. They haven't had a lot of firearms related things when I have been in there but do have a small section. Similar ratio of firearms to other gear as Quantico, just a very small shop. I think they do a lot of online sales and LEO and custom firearms built in the back rather than focusing on regular retail customers.
Blackwater is mostly firearms. Very large store but not packed like other places. They had an airsoft section that I believe is now gone. Last time I was in they were drywalling so things may have changed with more gear and things in addition to their large black rifle selection.
Owner is very nice and helpful and my experiences there are much different than what other people have posted. I'm in Salem weekly so try and stop in regularly to atleast look around.
Curts has lots of black rifles, suppressors, magazines, tools, and the largest Magpul selection I have ever seen. They always seem to be busy. A few belts maybe and Magpul slings but not much for soft gear. Prices seem to be very good for a brick and mortar and without some work searching, generally beat online prices for Magpul items. Small shop, with lots of magpul and guns.
Threat Dynamics has a 2 lane range and a simulator range. Almost nothing for sale except a handful of pistols and some random surplus things. Mostly just shirts with their logo. This is a range primarily and not a retail shop. Has a large selection of rental pistols to try out. I believe they are the only indoor shotgun and rifle range in the area. I've never been on
their range and only downstairs in their shop area so don't know details.
None of these stands out as the best. They are all very good, each with slightly different inventory. We are lucky to have so many good shops and the best one is the one closest to
you where you can develop a relationship with the owners and support your local gun shop.
Not sure how that rates as "tactical"...
