I wonder what is causing the stovepipe malfunctions?

The basic design is extremely reliable as in the 1911 tests, I think they ran 6000 rounds without a single malfunction. Maybe it was 5000, can’t remember for sure.

Most stovepipe jams in 1911’s seem to be caused by weak ammo.At least that’s what I found when reloading for them.

5000 rounds or 6000 rounds makes no difference.

If you ain't hit him after 4000, it's best to turn it into a club.
