I'll say... Issued to me at work! I've also been fortunate to purchase a few of them after they were retired from service.
So far I've been issued/carried:
65-2 4"
64 3" (off duty gun)
6906
4046
SW99 (Never carried but purchased one that was retired from my dept.)
M&P40C (Still carrying)
And between the 65 and the M&P40C I've added a few other 3rd generations in 9mm and .45 to the collection. My wish list is probably three times that long. Man these things are addicting!
