Do you want slim as in single stack or just compact? You might look into the .45acp or the .40S&W (although this one tends to sting abit in small guns). I would look into the Kahrs or maybe the new XDS which all of the big boxes seem to have for $579.00 right now. A co-worker was going to the DSM gun show this weekend to try and beat that price........I told him good luck
