I have carried a G26 in an ankle holster every day I'm working for the last three plus years, and a most of the time during the fall/winter, carry the same off duty and "lounging" around. I carry mine in a Galco Ankle Glove, and I find that, with the hiking boots I wear most of the time, the top of the boot helps support the muzzle of the holster, so it's pretty easy to forget about.
Previously, I had ankle carried a 642 and a PM9, and while the G26 IS chunkier and heavier, after about a week I got to the point where I forget about it. The fact that I can shoot it A LOT better than the 642/PM9/G42, and it feeds off the same magazines as my primary (G19) makes it a very attractive package for me...
