Review by Michael

For a long time i carried and relied on the 1911 for in-home and everyday carry defense pistol. I had been seeing the newer 45acp pistols, but they looked and felt a bit like toys. One day i was thinking about the original intent for the 1911, and realized that it was originally designed for a situation when you are out of ammo or have a jam in your main battle rifle in WWI. All this time I had been carrying it as my first line of defense, when in reality, it offered little more protection than a revolver. I went in to my local gun shop and said, I'm ready for more, and the Glock 21 is what they showed me. I have to say, that day changed my life be it 13+1! They do sell 27 and 30 round mags for these beasts which will take care of any general problem that I can think of. The way i see it you can either get the guns of the future, or you can die with the past.
