I wanted one for a while. It had everything i wanted for a HD gun chambered in 45. External hammer, DA/SA w/ the ability to be cocked and locked, high capacity, an accessory rail and priced reasonably at ~$600-$650. But then i picked one up and it is a very large gun. it takes some big mits to wrap around that grip. The only other gun that im aware of that has these options is the Taurus PT845.
My buddy had a 24/7 and it was a 12 or 3+1 45 but the grip wasnt that bad at all. THe PT845 is basically the same design with a few changes.
