Hey group,
I often carry my new pup in a Galco pocket holster as a primary weapon, but when I am working, it's a back up to a Kimber Ultra CDP 2.
I just purchased a PDA holster that is the same (I think) as the one the Taurus TCP comes with. I got it at Cabella's and it is a touch snug, but is fantastic as a carry option.
Yes it is a slight bit slow to draw, but not bad. It certainly is good for back up and is better than an ankle rig.
I highly reccomend it. $16 dollars + shipping.
