I am looking for a shoulder holster with two magazine pouches, I just got a S&W M&P 9mm, is there anything close to my size gun? or any holsters that are made for the M&P?
Well in all honesty this should be pretty easy. Shoulder rigs dont require an exact fit like most belt or IWB holsters do. You should easily be able to find a very nice "medium sized auto" shoulder holster that will work perfectly for you.
Because they utilize a thumb break for retention....many different guns can be carried in the same shoulder holster.
