Unfamiliar with centrefire handgun in an AR but have worked with different types of SMGs. Anything other than blowback seems to be more accurate, all other things being equal. Blowback is a big, heavy block slamming against the action at the critical point which is when the gun goes off. It knocks the gun off aim and down. With DI it's just the hammer so you will be able to take carefully aimed shots.
