Hello everyone,first post here. I am hoping some of you here can offer some suggestions. I stopped by Cabela's tonight and took a look at the S-A1. To make a long story short, they fit me like a glove. I was able to put both a 9mm and 40 cal on hold for 5 days while I decide what to do. I am a bit OCD and like to study up as much as possible whenever I make a purchase like this. Will you please give me your opinion on which caliber I should purchase? The gun will be used as my conceal carry gun. Is there anything else I need to be aware of? They are selling them for $499. Is that a decent price? They also had the M-A1 which felt even better in my hand, but I just feel that the S-A1 will be easier to conceal. Thanks for any help you can give!
