Slightly I do.
It depends a bit on whether this is going to be the only ecommerce site that you do, or whether it is one of many.
If it's just one of many sites then it is probably ok. Generic sort of name that is averagely memorable but describes a genre quite well.
It doesn't get a particularly high number of searches and so isn't really what people look for (by definition).
If it is a site that you are going to put your heart into then I think it is possibly a) too generic and at the same time b) too specific .
And to explain that apparent contradiction:
I noticed on flippa not so long ago a site selling martial art equipment/kit/gear and it looked like he was getting most of his money from selling training videos for different techniques featured by respected fighters. Note that it wasn't the equipment/kit/gear itself that was making the most money. So that explains why your name might be too specific. You may develop it in different directions and not want to get stuck with a name that doesn't fit your product (look at carphonewarehouse in the UK - really! there's a huge brand that is stuck with that name!)
At the same time it might not be specific enough.
Looking at keyword search quantities
fighting gear < 1000
fighting equipment < 1000
boxing gear < 10k
boxing equipment < 100k
boxing gloves < 1m
it looks like the more specific you get the more searches you get (as long as you're specific in the right direction!).So instead of fighting use boxing, instead of gear or equipment use gloves .
And I'd say if you've been successful with it, it would be nice to have had a slightly more brand-ish name to put your life behind - but it's just opinion and I don't have facts to back it up.
Best of luck with it whichever way you go.
