Hi, ive read a lot of forums on here but this is my first time posting one. Im looking for a good carry gun in 40 cal. I may carry it on my ankle depending on the situation so i need something that will hold up to the grit and grime. Ive pretty much got my decision narrowed down to The Kahr MK40 and the Sig P239 in 40 cal. I had pretty much decided on the SIG but when i went and held one it was a lot bigger than i expected which isnt bad per say, but i do like being able to conceal to a high degree. If any of you have had any experiance carrying either of these, and how they hold up to the dust and grime...........perticularly in the case of the kahr because i read about the homeland security torure test on the SIgs. Also info on reliability and just any advice in general would be awesome. I know theres a big size difference but these are the two i like.
