Acorn, I came to the same conclusion years ago, then I noticed all these good firearms chambered in 40 being sold at low prices because everyone seemed to think the same way, I have 9mm and 45ACP firearms, what need do I have of 40mm. Yawn. I collected LEO trade ins and saw a CHIPS 4006TSW for $250. OK why not. Shooting the 4006 was different enough and enjoyable enough to justify the different round. I tried it and I liked it. Several long term shooters with plenty of 9mm and 45ACP handguns who tried the 4006 went and bought their own 4006 right away. 40 caliber and the 4006 in particular is recommended. The round does not seem to be going anywhere soon. Join, you know it is your destiny.
