My first CCW was a Glock 27. It was easy for me to conceal and it was my EDC for about 5 years. I bought the Kahr MK9 when that first came out and ended up switching due to the much slimmer profile. It was more comfortable for me to conceal IWB. The weight was about the same as the Glock. I ended up switching to the PM9 a few years later and the much lighter weight made everything much more comfortable. It's my EDC now and I love it's slim slide and weight.
