Our dept. is using G22's and the .40 S&W. Fine.
Off duty yours truely carries a 1911 in .45 ACP.
A few other departments use the SIG 220/.45 ACP.
The transition to the .40 seems to be most predominent.
Had a nice visit with one of police officers today. They carry Beretta 9mm's and the ammo is Federal 9BPLE. He also carries a .380 backup along with pepper spray.
So I added one vote to the 9mm tally.
But don't believe I'll be using any 9BPLE, it's available from Ammoman to anyone. The +p+ round would be just too much for my little Kahr PM9. For a real neat "wetpack" ballistic test on the 9BPLE, check this link...
Interestingly enough, while the city has 5 times as many officers as the county and the city has many more shootings than the county, the city has never had a multiple hit failure to stop w the 9mm in the last 15 years, while the county has had several w the .40. The city has used various 115 and 147 JHPs, the county various 165 and 180 JHPs.
In the southern Arizona area, most locals and feds are carrying various pistols chambered for the 40 S&W. I own several 40s, but honestly I bought them so I could convert them over the 357 Sig. I think that is the round most law enforcement agencies should be issuing honestly.
A few federal agencies have seen the light (Secret Service, Air Mashals) and the last I heard Texas DPS was using the round as well. I have yet to hear of an actual shooting situation where they we less than very impressed with the performance obtained.
I also find it to be an exceptionally accurate round to reload, as I have yet to find a poor powder bullet combination.
