G26 in SuperTuck and Tuckable mag carrier. I have used the j-clips for almost a year without any real issues, but with just 1 pair of my pants, the rearmost clip would drop down and almost slip behind the belt. For the last month I have been wearing the loop clips. They are a bit harder to dress with in the morning, but I don't ever take the holster off during the day. If I can't have my gun with me, I just take it off and continue to wear the empty holster. I expect I will also try the Velcro option at some point. Regardless, this is my favorite carry rig and I highly recommend it.
No squeaks. I use a Wilderness Tactical 1 1/2" Instructors belt.
