Question: Does it have an opening in the seam for sling stud?
Document: I got this for a 410. The holder works great and the shells really fit nice. the problem is the back is tight and the front section near the grip is loose and twist easy.I took a couple quick measurements and got my wife to flip it inside out and make some adjustments to the lower seam. This thing its like a glove now. I mean really nice. I have another one of these on a 20 gauge that I need to fix.
ordered the shell holder for my 410. held the shells firm, not to difficult to put shells i,n and dose not slip. no complaints.
good:  very easy to slip on and does what I want.not so good. It does slip a little and I have to pull it back into place.
bought this for my sons 410 holds them just fine just a little fishing line and a needle and sew a 1 inch spot in the front and it fits like a glove  i would buy another on if needed works just like i expected it to  can only say its well made  and thanks uncle mike  by the way my 410 has a small front stock grip some may not need anything  but its well worth the money
Weak stitching. Started to give way just sliding it over a standard buttstock. Okay for the price. I will probably trade up for a custom leather one soon, this isn't going to last.
Was looking for a plain, read cheap, shell holder that I could rotate around the buttstock to put the rounds on the left side. Yea, I know, it's a right hand rifle, but it's what I learned on. It's a bear to get put on, but it works great.
Use in my PD / play shotgun to keep plenty of 000 buckshot handy. Tight hold on stock with no slip, yet shell remain firmly in place and slide out easily.
Uncle Mike's is known for quality merchandise at a fair price. This buttstock shell sleeve is no exception. It looks good and fits great. To all those who say it's too tight - try slipping it on from the barrell!
This shell holder fits good on my rifle stock. It keeps the shells handy for loading. It looks good too. I am pleased with it.
This is a great product for the price. It's nice to have an extra 9 rounds right on the stock for a quick reload.
Answer: no
