I have a problem with my Ruger SBHH, 44 Mag, that maybe someone might have had and remedied. While shooting either 44 Mag or 44 Special rounds, the cylinder base pin works its way out and the pistol will not cock. Once pushed back into position all is fine for a few rounds. Is there an easy fix to this problem or does anyone have any ideas? Thank you in advance for your time and help.
