Another great post , my question is a little off topic though. I saw a 4006 looks new at the gun store for around 500 to 600 , should I jump at this ? I'd have to put it on layaway but i was wondering if there are any things details to look at or are the respectively all the same. I have never shot a 40 & for some reason frown upon them a bit seeing as I'd rather have a 10mm & I own the 645 & 659 . They also have another 659 for 300 . Thoughts ?
