I haven't had as much experience with the Outlaw as I have the Peacemaker clones but I've never noticed them being much of a problem. No different than the SAA Colt styles really, as you said with your stallion, I've seen Peacemaker ones that were tight also.
One thing I have noticed, the Remington Clones I've had experience with all shot extremely well. I've wondered if the web under the barrel has anything to do with their accuracy.
