I am new to this forum, hope I do this correctly! In searching links and info on my Stevens 520 - I ran into your site showing numberous Stevens 520's, and 620 shotguns. I am hoping to connect with one of these members whom can assist me.
Though, my 520's have long barrels, and certainly can not be termed "trench guns", they nonetheless function the same and have the same internals.
I have not fired a live round from my Stevens as yet, but - I have played with it enough at this point to beleive that it would operate fine under battery. with one exception - the cartridge stop lever. It is my belief that a cartridge stop would hold the next round in the tube, until the fired round was ejected, and the action brought forward to load the next round. That this cartridge stop would hold this next round via small lips on the upper and lower portion of the stop.
This does not happen on my 520's. When I load my magazine, the rounds protrude from the tube about 1/4 inch and rests on the lifter. I can still action, load, and eject a full magazine without problem, but - is not the cartridge stop intended to hold this next round in the tube until ready?
The stop has a bump towards the rear of the stop, so that when the breech/ bolt moves rearward, the bolt rides on this bump thus piviting it upward. There is also a screw in the receiver towards the front of the stop, and the stop has a bevel cut in the back of the stop, so that when the bolt rides the rear stop bump, and the stop pivits upward, it hits this screw head, and moves outward a small bit. Then the bolt is actioned forward to pick up the next round, and the stop returns downward, back against the receiver's inside wall.
I see this happening as i play with the action - but, no where do I see the stop holding a round in the tube. Nor, do I understand which edge of the stop is susposed to hold to round in the tube. and, of course, How the stop's piviting is susposed to function in relation to the stop's ability to retain a round in the tube and guide a round into the breech area.
Does anyone understand what I explained? Given that these shotguns or old, and parts are worn, one of my 520's has a cartridge stop that appears to be well defined, sharp and should function. The other shotgun's stop is well worn - and I could swap it out with a better one, but - i'd expect that it would not operate any differently. rounds would still rest on the lifter.
Can one of you more knowledgeable members help me out here. And, explain the proper operation of the cartridge stop, how to fix mine, and what to look for in repairing my rifles.

Note this cartridge stop's definition and clarity. I presume that this stop is in sufficient shape to function correctly. Breech is towards the rear of the receiver, the stop has pivited upward on the receiver's stop screw, and the stop has moved outward from the receiver. If the bolt was brought forward, the stop would pivit downward, off the stop screw and rest closer to the inside of the receiver.
