So today on my lunch break for the heck of it I decide to go to Discount Gun Sales LLC in Tukwila 'cause I like looking at guns and just picked up my uber awesome Glock 20SF last night and was hoping maybe they had some 10mm defensive loads. I walk in and ask the guy (didn't catch his name but the young clean cut looking asian guy) if they have any 10mm ammo. He says yes and hands me some bag (not even in a box) of 10mm plinking ammo for $34 a box, and even before I can say I'm looking for defensive loads or I don't want what he has or that it's kinda steep for what it is.....he goes into a lecture about how "10mm is an extinct round and a novelty" and "so is .357 Sig". He they tells me that "a .40 S&W +p will do the same thing as a 10mm" and that "9mm +p will do what a .357 Sig will do". Now I don't own a .357 Sig so I'm not to up on it's ballistics, but I want this guy to show me a .40 S&W +p round that will push a 200gr Wide Flat Nose Gas Check Hardcase bullet 1300fps with 750 foot pounds of energy, or 135gr. Nosler Jacketed Hollow Point 1600fps with 767 foot pounds of energy. Too really top it off (now that he'd lost a sale in ammo potentially), this bozo tells me if I have a 10mm or .357 Sig, that "you should get rid of it". Are you kidding me? Who taught this numb skull about customer service?!? One thing I would assume that any salesman understands is you don't talk down to them and then basically call what they like/own/whatever junk or inferior. I get people coming into the shop I work at looking for defensive ammo for their Lorcin .380, but I'm not going to say "sir, your gun is a cheap piece of S***. Get rid of it." Now, I realize that 10mm doesn't have the following of .40 S&W or .45 ACP, but this is "the round" as far as I'm concerned in an autoloading pistol. I bought a 10mm for a purpose, it's superior ballistics. I love the round and I'll probably be one of the last guys riding 10mm wave. I had been into this location before and they seemed ill informed of their products and what is out on the market. On top of that, I've had customer service issues with the location in Lake City Way. Walked in and told a salesman there I wanted a gun they had on the wall, didn't ask a bunch of dumb questions or try to haggle, just told him I wanted to buy it. The guy acted like I was inconveniecing him by purchasing the gun. I won't be shopping with them again.
