Glock 31 Ka boom
After the first kaboom, I detail stripped the complete pistol to look for cracks etc, the pistol was reassymbled. I checked the remaining ammo for OAL and pulled bullets to comfirm powder weight, everything was correct. The powder weight was midway between the starting load and the max load listed in a new Lyman reloading manual. Then, believing everything was safe, I gave it another try. I know of other Glocks that kaboomed over the ramp, that was reassymbled after a careful inspection, and ran without further problems.
Glocks, will fire out of battery, if you don't believe me, pull your slide back a little, and place something behind the slide, [a small paper match, thin plastic etc.] and pull your trigger. It will likely fire. Since the 357 sig headspaces off of the case mouth, a case too long, or one that the SHOULDER HAS NOT BEEN SET BACK ENOUGHT, could cause the pistol to fire out of battery. Glocks , and perhaps some others, will fire out of battery. A little bit out of battery, may be all it takes to cause a problem. I has other Glocks, this is the only one that has caused a problem. I have fired many rounds of Remington brass reloads without any problems. This was new PMC brass. I blame the brass, But Glocks are more prone for this than other brands in my opinion, but I'm not selling any Glocks, and I plan to continue using this model 31 when it returns from Glock. I will stick to major USA brand of ammo and brass. By the way PMC was owned be a korean company and is now out of business. I agree with the poster regarding that this doesn't happen to Rugers, I am a Ruger fan also.
