Bedwas' slender hopes of progressing in the British & Irish Cup came to an end as Stirling came from behind to deservedly claim the spoils at a sodden Bridge Field.
The Scottish side gained revenge for their defeat to the Welsh Premiership team last weekend with a 25-26 win.
Early drama saw Stirling outside half Stuart Edwards sin binned for an innocuous off the ball push on a Bedwas player.
The home side then opened the scoring after seven minutes courtesy of a try in the corner from Matthew Pewtner. Ethan Davies's conversion hit the post.
From the restart, Ross Wardle's fine run deserved a try but he was tackled just short of the line and the ball was cleared to touch. Stirling won the lineout and spread the ball for centre Mark Bennett to score a well worked try. Bennett's conversion attempt also hit a post.
From the restart, Bedwas winger Rory Budina set off on a run down the left only to be tackled just short of the line. Stirling launched a counter attack and were rewarded with a penalty for holding on which was kicked by Edwards.
Bedwas upped the pressure and good work by the forwards saw the visiting pack driven backwards at a close range scrum and a penalty try awarded, Davies' conversion successful.
Ross Wardle extended Bedwas's lead after 33 minutes after good work from Budina but again the conversion was missed. Edwards then added a penalty after Bedwas were adjudged offside to take the score to 17-11 at the interval.
Edwards added another penalty after 45 minutes to reduce the arrears to just three points before Pewtner added his second try. Stuart Thomas who took over kicking from the injured Ethan Davies, missed his kick. Thomas made amends five minutes later with a successful penalty goal to put Bedwas 25-14 ahead with 25 minutes left after Stirling were adjudged to have collapsed a scrum.
Stirling refused to lie down and following a penalty Reyner Kennedy was driven over for an unconverted try to put Stirling within six points of their hosts.
Bedwas had an opportunity to extend their lead but Thomas's penalty attempt went wide before Budina attempted to latch onto a Thomas hack through though the ball went dead.
Stirling scented victory and camped in the home 25 with four minutes left, centre Danny Gilmour broke through to score under the sticks. Edwards added the simple conversion and Stirling celebrated a fine comeback.
