Another plus the 1911 holds over the Glock, is the ability to shoot lead projectiles.
And SWC shaped lead projectiles to boot! My 1st gen G-17 would not run SWC. A friend of mine bought a G-36 and it will not run lead SWC either. With the exception of a mid-70's Colt GCNM I used to own all my 1911's have run SWC without a problem. The GC had other problems as well so the ammo issue was a by-product and not the primary problem
