As part of my overall plan of combining calibers of weapons to minimize ammunition loads ( described here ) I purchased a new firearm yesterday.
Under most circumstances, people might have an AR platform carbine as well as a side arm. More than likely (though not always) of different calibers. My goal has been to do what I can to make sure that I have a carbine and a sidearm of the same caliber to make sure I can feed both weapons with the same box of ammo.
I have taken it a step further. I can not only feed my carbine with and sidearm with the same ammo, but I can now feed them with the same magazines.
With much thanks to Mr. Brett Busbee at Southeastern Armory (website) I can now do this. Brett made it possible for the purchase of a Glock 17. The Glock 17 magazines also feed my KelTec Sub 2000, the folding 9mm carbine.
For ease of portability and use this is probably the best scenario, for me that I could put myself in.
The G17 is a big gun. Not the best choice for a concealed carry weapon so for everyday carry I will stick with my Ruger LC9. Small lightweight and easy to conceal. But if any situation presents itself where a carbine might be required, concealment is probably not my concern and the G17 will be available.
