It may be possible. But I wouldn't recommend it. Especially in a carry gun. Anything that isn't to factory specs on a carry gun could be used against you in court if you are forced to use the gun. Messing with the trigger could change a self defense shooting into a negligent shooting.
My gun would be screwed then. It's not even the original caliber and I switched to an SRT trigger (which doesn't affect trigger pull, just how far). That and I was planning on a recoil reduction system, so my gun's as far from factory as possible.
When they kick out your front door, how you gonna come. With your hands on your head or on the trigger of your gun?
