We have the 229/239 in DAK as standard issue. We have a limited number of Glock 26 and J frames (probably less than 500) left over from the days of customs as issued pistols.
For personal purchase duty carry, we have:
Glock 17/26
Sig 229/226/239 in DA/SA .40
HK P2000k LEM
HK USPc .40 LEM
All of those guns were approved for personal purchase because at one time they were issued guns, and as such had already passed the testing protocol.
It is hardly a "Bazzilion" pistols.
The majority are cheap and stick with the issued guns. Half have bought the 26 for off duty use. About 20% bought the 17 to go with the 26. About 10% carry J fram back ups. Only 5 or 6 people went with the HK (it is not very popular with our troops).
