My previous post was highly Sarcastic, and I think you misses the main point.
That was that all manufacturors have parts fail from NORMAL use. That is because no mater how good your quality controll is, eventualy something will slip through. While Glock, Colt, Sig, Springfield, and the like are extrodinary weapons, they are not exempt from this.
Even if the integrity of a companys parts are normaly fine, there are MANY un-forseable factors that are beyond the factorys controll. Anything from an over-sight in the steel-makers facility, to a cold-spot in the manufacturors heat-treating kiln. These are all things that would NOT be apparent untill many rounds have been fired, and something that the factories test-firing would NOT catch. These likely causes are also soemething that are likely coved under warenty, and if not, are easily and cheaply repaired by a smith.
Spanish made handguns like Bersa, Llama, and Star are also known for being of a quality far beyond their usual $300-$350 price tag.
in other words, it is likely, yea PROBABLE that this defective hammer was beyond the controll of the factory.
THAT sir, was my point.
