No problem, always glad to help out.
I haven't had any issues with the gun cycling anything at all. Low brass cheap stuff from walmart, remington bird shot, buck shot, slugs... it just eats whatever you put in it whether I have had the side saddle on it or not. I also have the surefire forend on it which im sure adds a little bit of weight.
I bought my 14" entry model as a police trade in that had been fired, but is in great condition, so I am fairly confident that it is well worn in and I think that it being loosened up helps it to cycle so well. Not totally sure on that, just a theory!
