Failure to feed on last round - ProMag Ruger SR40 10-Round .40 S&W Magazine

I use the ProMag SR40 magazine for my Ruger PC Carbine and found that I kept getting Failure to Feed on the last round. The follower on ProMag is different from the OEM Ruger magazine and does NOT grip the last round to keep it from creeping forward and causing the Failure to Feed issue.

SOLUTION: I applied TALON Grip to the follower and the Failure to Feed issue was NO more!
