Ilkay Durmus' 73rd minute free-kick salvaged a point for St Mirren as the Buddies drew their third Ladbrokes Premiership match in a row.
Saints found themselves behind to a 25th minute David Templeton strike in a lacklustre first-half showing for Jim Goodwin's side.
But a better second-half performance saw Saints grab a point with Durmus curling home from 20 yards after Ryan Flynn had been fouled.
By the manager's own admission the Buddies were not at the races in the first 45 minutes and Hamilton capitalised with 25 minutes on the clock. A long ball forward from Accies captain Brian Easton found Mickel Miller who beat Calum Waters to head the ball into the path of Templeton who slammed home from 25 yards out to give the visitors the lead.
It was a controversial opener given Accies goalkeeper Luke Southwood had clearly handled outside his box just 20 seconds earlier while Waters was on the ground with a head knock after clashing with Miller.
Saints tried to bounce back in a positive fashion with Durmus heading wide from a decent area inside the box after meeting Morias' cross.
But two minutes later Templeton was just inches away from adding his and Accies' second when he flashed just wide from 20 yards.
And with seven minutes remaining of the half, Vaclav Hladky kept the scoreline down as the game ebbed towards half-time when he got the slightest touch on Marios Ogkmpoe's ferocious effort from 25 yards to touch it on to the bar.
The Czech goalkeeper also managed to gather on the line after a scramble inside the Saints penalty area following a Hamilton corner on 43 minutes.
In truth Saints were lucky to only be 1-0 down at the break, but started the second-half the brighter of the two sides. Lee Hodson, who replaced Jamie McGrath at half-time, played a low ball across the face of the box with less than two minutes of the second-half played where it met Cammy MacPherson. But the Saints midfielder scooped the ball over from 15 yards.
Tony Andreu was presented with a wonderful opportunity as the ball fell to him inside the box on 68 minutes but the Hamilton defence did well to block and deflect narrowly over.
With just over 15 mintues remaining Saints would find themselves level. A really poor challenge from Mickel Miller on Ryan Flynn saw Saints awarded a free-kick right on the edge of the area. After a delay which saw Flynn receive treatment before being substituted, Durmus stepped up to confidently curl home into the top corner to equalise.
St Mirren would have hoped to kick on in the final stretch of the match to try and find a winner but were dealt a major blow just two minutes later when Hamilton were awarded a penalty kick. Hodson's flailing leg brought down the forward who had nipped in just ahead of the Northern Ireland international. It was Miller who grabbed the ball to take the spot-kick, but despite Hladky diving the wrong way, the striker sent his effort wide from 12 yards.
Saints were denied their own penalty in stoppage time when substitute Alex Jakubiak appeared to be hauled down in the box, but referee Alan Newlands was unmoved.
