I had a Sr9 for 8 months ,it had to go back to ruger in the first 4 months , the trigger was heavy-[lbs], the barrel peen up . Even after new barrel was install ,and 450 rds later the shot group did spread out! Their quality control is a crap shoot!
I traded it in on the Mp9c and it is way better made inside + out!! I got close to 500rds threw it now and NO troubles at all...Its shoots more accurately for me,fast follow shot are quick. After about 200 rds the trigger smoothed out great! I paid $125.00 more for the Mp9c , my life is worth it !
