It should not be a surprise to anyone that it is difficult to get consistent supplies of ammunition these days. Unfortunately, that means that the quality of what is being fed into our guns might be a bit (lot) lower than it has been for a while.
It has been several years since I’ve worked on a pistol that suffered a ka-boom. Last month, a personally owned Gen 3 Glock 22 came across my bench at work after one of those events. The owner had been firing frangible rounds from a commercial reloader. I ended up having to replace the internals in the slide.
The case head wasn’t recovered, and there was a tear in the case at 3 o’clock – where the extractor claw would be – and the case has blown out to match the shape of the feed ramp.
Just a reminder, even when ammunition is scarce, take a second or two and consider what you are feeding your firearm. New? Re-manufactured with once fired brass? Or have the cases cycled through the reloader several times?
