Taken from one of my previous postings:
The main reason I shoot the Glock is because of the 1911. I hate the 1911 because:
1. After thousands of dollars worth of quality gunsmithing work by American Handgunner Club 100 gunsmiths, with every part of the gun tuned or adjusted for maximum reliability, 1911s, in my experience, will still jam, FTF or FTE, never in practice and always during a match . You can take a Glock out of the box, check the bore for grease or obstructions, and take it out and shoot it, and it will run.
2. Glocks have no grip screw bushings or grip screws to come loose. Most new 1911s, in my experience, will have at least one grip screw bushing come loose when you take the grips off the first time, and it is usually attached to the grip screw itself, and it screws out of the frame.
3. A stock Glock does not hurt your hand and draw blood when you shoot it, unlike a 1911A1 with the stock hammer and the stock grip safety (YMMV, but it does it to me).
4. A stock Glock does not have to have aftermarket expensive magazines to function properly (ie Wilson's). IME the magazine that comes with most 1911s was made by the lowest bidder with soft metal bodies and feed lips. You do not have to "tune" the magazines or buy aftermarket magazines for a Glock.
5. The number one PITA with a 1911, the extractor. Most 1911s out of the box will have to have their extractor replaced with a better quality unit to maintain extractor tension. The Glock extractor is fine out of the box.
6. Glocks do not have plunger tubes that will come off of the frame. I once had a Series One Kimber, and during shooting the plunger tube came off. A gunsmith charged me 50 DOLLARS to replace that plunger tube (at that time about a six dollar part that took two minutes to install). That is the main incident that attracted me to the Glock. No plunger tube.
YMMV, but these are the main things that make me hate the 1911. Too much money for not enough gun.
Just my .02,
