The new deal will keep the defender at St Mirren until the summer of 2014.
“I’m now looking forward to the next two years,” Barron told the club website.
“I think it is fair to say that I’ve had my fair share of injuries so hopefully now they are all behind me.”
“I would like a good run at right-back which is my natural position,” he explained.
“To be honest, I’ve only played in that position about three times in the last three or four years as I keep getting moved about between left-back and centre-back but I really don’t mind doing that as the important thing is to be playing.
“I’ve really enjoyed playing at centre-mid this year, which I didn’t think I would be doing, so I wouldn’t mind playing there but if given a choice I would like a run at right-back.”
