I do agree with several posters above. The Glock is so relatively light that limp wristing will result in the slide to have little mass to anchor itself against in moving back, and ejection jams occur since timing is thrown off.
Mr. Havey,
As my first, and still only, semi-auto pistol, I acquired a Walther P1 a few years ago; it's the post-war successor to the P-38. It arrived in brand new condition but when I fired it, it quickly, repeatedly jammed. the magzines were equally "new".

The importer quickly sent me two or three replacement magazines, used ones, and, since then, I've had zero stove-piping occurances.
