Exclamation Magical Mystery tour: common reasons for KSC GLOCKs cycling problems

Hello all,

since I'm getting cycling problems with my Glock 26, and because I've been swapping a lot of parts, I'd like to know what are the most common causes for pistol-related cycling problems (as opposed to magazine-related problems)

from reading aroud, I understand that a cycling problem is often caused by:

Quote:

KSC glock manual: http://www.pegatiros.com/download/de...1-ksc-g17s.jpg

the common causes for failed cycles are:

cold temperature

insufficient amount of gas output-->
not properly loaded magazine
weak/worn hammer / hammer bar bent ?

insufficient blowback-->
previous causes or
bad sliding action (high friction) / bad nozzle action (high friction in the chamber ?)
broken rocket valve
rocket valve weak spring ?
bad chamber-to-magazine seal, gas gets lost ?


failed hammer cocking-->
previous causes or
recoil spring too strong
hammer spring too strong?
Cracked hammer sear (part #87 or 83 on KSC) will cause the hammer to sit about 1mm higher when cocked, and it either prevents or slows the slide from cycling.
bent or fucked hammer bar
bad valve action on the magazine! fiddle with the valve!
bad luck.

failed chambering-->
previous causes or
recoil spring too weak (weak slide return)

Also:
chambering without hammer cocking-->
broken hammer sear/ ( the hammer will stick up anywhere from 1mm to half cocked to no cocking at all)

correct clycling when no BBs in the mag, no cycling or problems with a mag full-->
?


too much internets-->
limp wrist


thank you!
