I fired the keltec 9mm with glock mags that a range buddy had the same day I fired my sunny hill. So I could do a comparison of fit anf finish etc. THe keltec is good for what it is: a cheap truck gun with a lot of plastic and poor finish (but good functionality).
The sunny hill is a totally different firearm in a different league altogether in terms of quality, fit and finish.
IMHO, keltec 2000s at $299 are a good deal, but at current rates of $400 plus are overpriced. THe sunny hill is fairly priced and actually quite economical, when you look at its fit and finish and quality.
Oh, and I am not a snob. I like the hipoint 9mms I have shot too. They are good value but again nowhere in the same league as the sunny hill carbine.
