I have bought 5 of the Stoners, they are a great mag. I only load them with 9, the 10th seems a little tough to get in, maybe after I break them in they will be different but for PDog hunting the 10rd Mag works very well and doesnt get in the way. I tried the 10 round Thermold...I threw them away, I didnt get good performance from them. A cheaper alternative is the 20 round Thermold, they work great and dont stick out very far at all, CDNN sells them for about $5 a piece and I dont load but 10 to 15 in them. I use them a lot also. My 30's stay in their pouches in the closet unloaded I just dont use them. When someone comes over to shoot and they always want to shoot one of my AR's if I hand them a 30 round mag loaded with 20 or 25, after about 10 to 15 shots I start thinking about how much work and how much it is going to cost me to reload all those rounds. LOL I am not cheap, just frugal.
