I think the DW mags are Ed Brown, but i also used a set of MecGar's.. Didn't pay attention so can't remember which mags were in when the issue occured. I'll check next time and note it down..
Also noticed that it's best to remove the grips when i clean the gun.. else the gun oil starts to seep the dye out of the grips, get's messy...
And another thing i noticed, is that the Stainless get's dirtier then a blued or parkerized gun does.. Or rather it's much more noticable. But hey , cleaning it is fondeling it.. It's fun too.
