They also make a version in 6.8 SPCII, which you may want to consider for more power and increased range.
If more power I'd probably go for a military style wood semi-auto in one of the .30 variety. 6.8 is probably great, but I don't want a new caliber in my house, if I can avoid it. Although maybe a 10mm someday
What features make the Daniel Defense desirable compared to the less expensive stuff? Asking because I really don't know much about any of these guns.
