There will be no appreciable difference in accuracy or precision barring any defect with either barrel length. However, a longer sight radius does help when seeking precision from a particular weapon. Sight radius is not dependent upon the barrel length. Without going into serious details I can say with confidence that having a 3 inch barrel will in no way decrease the effectiveness of your weapon for the intended purpose.
Hi Leland and welcome. 3.3 is sufficient. A 4 inch gives a couple of benefits, longer sight radius for aiming and 40 to 55 fps extra velocity from the same ammunition. Cheers, stay safe and enjoy!
Hi Leland, a 3.3" barrel is sufficient. Stay safe & have a great day!
