Price, was one factor and I can tell you from talking to them, they are not happy with it, talked to one who said he knew of a shooting where the CD passed thru the windshield and lodged on the OUTSIDE of the BGs skull..from like 20 feet. I will stick to my GD's and Ranger T's. I carry a 40 for work and have carried a 357 Sig. wont ever carry a none for duty..defense yes, duty no. JMHO

I started out in law enforcement with .38 lead hollowpoints and finished up with Winchester Ranger .357 Sig 33 years later. I was fortunate to have never been in a gunfight, but did learn a truism from several fellow officers who were that has withstood time:
---
An agency can test five different brands, three different calibers, nine different bullet weights, six different jacket/hollowpoint designs, and four general bullet speed ranges, and then issue one specific round that it hopes works best in a particular deadly force encounter where any number of variables (distance, barriers, suspect's clothing, bullet placement) can render that carefully selected bullet ineffective in a gunfight.

The only variable that truly counts is the officer's ability and will to fight to stop the deadly threat.

There is a single agency I follow as their mission is closest to that of personal protection. They're why I carried 357Sig and why I have moved to 9mm. That agency is the secret service.

Anecdotes aren't data until there are enough of them to establish a trend.

We had a bad guy shoot another bad guy this summer with a 10mm. Unknown load. Bullet failed to penetrate the skull at the brow and the base of the projectile was visible. It was the damnedest thing, but hardly enough to condemn the 10mm.

One hundred successes (whatever that might be) demonstrates what is likely to happen in the future, and therefore what we can anticipate with reasonable confidence.
One failure (whatever that might be) demonstrates what can happen.

When the question is terminal ballistics and its effects on threat-neutralizing performance, there are so many possible variables at work that a tiny sample size proves nothing. A sample size of one doesn’t tell us what’s likely to happen, and much less why it happened. Just to cite one possibility, one of the many firearms safety rules shooters should be familiar with is that ammunition is sometimes loaded to underpowered levels. That can result in bore blockage, but also unusually low velocities and poor performance.
