Loose trigger question

Hi
I recently bought a used Colt 1911.  I am having a terrible time trying to shoot this thing..
I realise the trigger is much different than my 41, but I can't seem to shoot this thing straight.
Not trying to blame the gun but the trigger seems awful loose side to side. So I have to basically center the trigger then pull it back. My question is should there be any play side to side ? If not where can I get an oversized trigger? 
The oversized ones I have seen advertised were oversized top and bottom not side to side. I'm thinking this side play makes it easier to pull it off target.  Of course if they should have side to side play, it's just me.
Thanks for any advice , Tom

Aftermarket trigger bows fit the frame better than stock triggers.but triggers can be modified to remove all excess side to side play.

Pretty sure this is an after market trigger.
How can it but midified, bending out the bow ?

Brownells sells 1911 trigger stirrup die, it can be used to resize the trigger bow to specs (unless your frame is out of spec).

Be cheaper to buy the length of Greider trigger you want and fit it. Brownells carries them.. they are IMHO the best trigger out there and not expensive.
