Almost seems to good to be true. I would say go for it if it's as nice as you say. If you end up not liking it I'm sure you could get your money back out of it pretty easily. Good luck
I already have a Glock 22 but I'd buy it at that price. As noted above, you won't lose anything if you decide to sell it later. If you can spare the money right now that's as good a place for it as any. Savings accounts earn virtually no interest and the stock market sucks. Go for it!
