Glock 22. My department "upgraded" from the Glock 17 in 2001 and we spent over 10 years regretting it. We have had so many issues I could not even convince the powers that be to go back to the excellent Glock 17 (Gen1-3). No more Glocks, but now we issue M&P's and couldn't be happier. I wouldn't trust a Glock 22 to prop a door open reliably.
