I was going to buy a mosquito last month, for the looks, price, and SIG name, I thought I couldnt go wrong, but as always I started to do research. I found an ABUNDANCE of negitive reviews and experiances almost all having to with being too picky with ammunition, and even with recommended ammunition there were still many missfires. In my opinion even with the price, in light of these reviews it seems not to be worth the frustration. However could have been older production models... not sure, still not worth it.
