I cant figure out why hardly anyone uses them. It almost seems that I'm the only guy on the planet with one. The .40 does way more terminal damage (around 80-100 pounds of kinetic energy more or something) than the 9mm. It has a 10 round mag which is more than long enough to last a self defence shootout. I have never had any problem or reliability issue with mine even though it is the only gun I have that I left in stock condition. Is there something about this piece that everone hates?
