I recently purchased a S&W SD9VE. What is the average life expectancy of the weapon and what is the comfort of OWB carry for a larger person? It is a gift for my Father-In-Law and he is a big man in desperate need of an upgrade (He currently carries a Hi-Point that is about 10+ years old). So, in other words, as far as actually carrying the weapon how does it compare to the Hi-Point? (I know the quality, this is about comfort.)
