I tried the Uncle Mikes ankle holster before buying this one and this is much more discreet and comfortable. i bought it for the model 21A bobcat and it fits perfectly. the velcro on the top is a bit tight but it's stretchy so no big deal, but the velcro on the bottom doesn't stretch and it fits a little tight on my ankle. the one piece of velcro barely reaches to the other. Overall, it's a great holster, very happy with it
