If you spend your day sitting down, an ankle holster isn't a bad way to go. Galco makes a pretty good ankle rig with neoprene padding which is quite comfortable once you get used to it.
As someone else said, a G26 is really too wide to conceal easily in an ankle rig. It can be done (I've done it) but it simply doesn't work that well. Frankly, the best gun for an ankle rig is really a lightweight snubby. Don't tell anyone I said so...
The draw is awkward, and
must be practiced. Some of my LEO friends who carry their backups in ankle rigs have put velcro on the lower inner seams of their pants, to make the draw faster. This really works, but is a royal pain to do. And of course velcro can get gummed up; you've got to launder carefully so it doesn't come unstuck in public.
You cannot draw from an ankle rig while running away. But you can draw while sitting, while crouched under your desk or behind cover. And although it is slower than a waistband draw, if practiced it can be done pretty quick.
Basic technique is to stick your left leg out in front of you while crouching with your right leg. Try not to put your right knee down if you can help it, because that slows you down if you need to move in a hurry. Move your pantleg out of the way with your left hand, draw with your right, stand up and you're good to go. Or you can fire from the crouch, if you've practiced it. As you can probably guess, the draw takes flexibility and good balance. Um, also, loose pants.
If you're in a chair, your can simply bend over to draw, or bring your left ankle up to your right knee and draw from there.
Keeping the gun concealed in an ankle rig requires pants that are slightly longer than you would normally wear, and looser around the ankles. You have to avoid hitching your pants up when you sit down, too, and you can't thrust your legs out in front of you & cross your ankles, or cross your legs when you sit down. Basically, you have to avoid doing anything which might expose your socks.
HTH.
