I've owned a couple of 9mm carbines (older model PC9 and Camp9) for close to 2 decades. We shot them for fun and I used to keep one as a bedside gun. Using 147 grain bullets and red dot sights, those carbines are suitably accurate for home defense use past 100 yards.
I've spent some time shooting the pair of AR9 "pistols" lately and have found them far more accurate than one might expect. Both the 7.5" and 10.5" will consistently smack the 4" swingers @ 50 yards. The 10.5" doesn't much care what weight or velocity load is used but the 7.5" seems to prefer either 115 or 147 at factory velocities.
The 10.5" is a cloverleaf performer with 147 sub-sonic. The 7.5" is a work in progress. Both however, will push the little handgun round into rifle territory w/o much effort.
