I would like to put in my two cents as a 1st SGT in the Tennessee State Militia and a Retired Police Officer. Our group decided to look into the XDm 45 Tactical as a service sidearm, which we did adopt. It is a great firearm in and of itself. The M9 has been the standard sidearm of the United States Navy, United States Army and the United States Air Force since 1985, replacing the Colt M1911A1 in the Army and Navy and the Smith & Wesson .38 Special in the Air Force. The M9A1 is also seeing a limited issue to the United States Marine Corps.
Although the M9A1 is a nice firearm I was never a huge fan. And now that I see the contract that SIG just got with the M17, I have to favor with that choice. I would have to say, at this point and time it looks as though the 9mm round is going to be the most abundant when the SHTF. The added Benefit I see to the Sig M17, is we are going to have access to all the parts we would need to keep ours running. This is a huge factor when they try to remove our arms and we tell them to pound sand!.
SIG made this sidearm for a reason. You can interpret that reason however you choose. I believe that they made a firearm that is worthy of Military and offer "We The People" this same sidearm. When the M9A1 was offered service terms, we as a people couldn't even get close to that model. The Brigadier is the closest you can get. With the M17 there isn't much other than color choices. All of the frames, slides, barrels, pins, triggers, are interchangeable with every other P320 out in the population. The Modular System is an awesome concept.
As for a rifle, I am more in favor of the Reach out an touch someone theory. I know guys who are "Old School", who will swear by the 30-06, and some the 308. I fell into the whole hype on the 6.5 Creedmore, but now I hear the Military is going to the 6mm. If they do go 100% with the 6mm. then we have another whole playing field. the AR Platform is going to be as worthless as your sidearm in a firefight. We all have to remember this, "From a place you can not see, comes a sound you will never hear". That is the motto you have to pay careful attention too.
to sum up, my choice for the future of my groups I am suggesting the SIG M17 9mm as a sidearm, some form of Tactical 556 cal, and a really nice 6mm setup. Then you can build up from there. But always keep your eyes open for a change in the Military styling. It makes perfect sense. We will be armed with the same weapons as the very Soldiers we may fight with or against. I can only suggest you take heed in my words and consider this sidearm for a standard service pistol for all of our brothers out there. It is worthy of consideration. God Bless, HOOAH
