My only comment on those who stovepipe a Glock is they have limp wrists. Long time no hear Chris!
A lot of those Indiana State Troopers musta had limp wrists, particularly those from the Firearms Training Detail at the ISP Academy, and those on the ISP ERT [SWAT]Team, who were issued two Glocks, one with a mounted light and one without.
Interestingly, once they switched to 9mm Glock 17s, the stovepiping ceased. I had the happy opportunity to trade fora .40 Glock from the same batrch from a county deputy en route to the Academy, who wanted a gun that worked. The only feeding problems he had during the 1170 rounds he fired was when dummies were included in his magazine for *clearing stoppage* drills.
I put around 300 rounds through his G22 and had no problems, but at that point went to a .357 SIG barrel, and still haven't. I don't shoot it a whole lot, mostly it's along for someone who has heard about .357 SIG and wants to try it. He'll want it back someday.
