what are the ingredients of Gaston Glock's success? 1. striker fired pre-cocked DAO -simple manual of arms makes it desirable for police and military. not so great is the "pull the trigger" disassembly which is a flaw in it's manual of arms that gives the S&W M&P a good niche to exploit. 2. modified Browning locked breach -it's a strong action suited to a variety of powerful chamberings. the barrel locks with the slide at the big ejection port. simple to machine, strong and reliable. The easy feeding loose chamber is also something Glocks have in common with the AK. 3. polymer frame and stamped parts -high start up costs for the equipment but production costs are very low. it is arguable that glock could have lower costs with a stamped slide like the early ugly Sig-Sauer but now CNC costs are much lower. cast parts are also very common now.
