Hi all. Just started getting back into hand guns after not owning one for several years. Like many hear I'm a military veteran. 12 years Army disabled. I recently moved back to the city and noticed the crime so I went out yesterday and picked up a new Sigma 9mm. Have a couple of questions which I'll post in the semi auto forum. I have owned a Mossberg 500 since 1985. Has Patchmeyer(sp) grips and 18.5" barrel.
