As of today, here are the latest results:
-Total guns polled: 87
-Total with internal extractors: 50
-Total with external extractors: 37
-Reliability with internal: 47 reliable, 3 unreliable, 94% reliability
-Reliability with external: 19 reliable, 18 unreliable, 51% reliability
-Reliability for all pistols: 66 of 87 pistols, or 76%
Again, this is very informal, and not the most scientific. However, there is most definitely a trend here.
