I ran a test batch of the 20, 15 and 10-round magazines through my 581-S last summer and couldn't wait for these to finally be in stock so that I could buy more. The description says they'll be sticky the first couple of times, but the ones I tested were not. They loaded to full capacity and fed without a hitch. They absolutely blow away the OEM magazines. CSSPECS has done what Remington should have done from the outset. These are just the best magazines anywhere.
