There has been a lot of speculation about the Glock problems. Three theories have emerged: some units have a timing problem in which they will fire before they are completely locked up; unsupported chambers could lead to case blowouts with both factory and hand-loaded rounds; some of the Glock barrels seem to have a metallurgy problem, i.e., they have measured out pretty low on the Brinnell Hardness Scale. I have replaced the factory barrels (with KKM Precision barrels) on my Model 17 and Model 21 and will soon do the same on my Model 22.
Depends. I got Shanghaied into helping out a pal who was calling in favors from every Dillon reloader owner he knew who got a contract to reload a hundred thousand rounds of .223 for a state prison system for training ammo for their mini-14s and model 700 sniper rifles. It was an interesting week's effort, during which I was supplied with all the free cokes and pizza I could handle, the cost of which was an arm that was sore for a month. I had a primer pocket swadger and ran every one of those little cases through it, pulled the handle, and dumped em in a 6-gallon bucket. I wore out 3 pairs of cotton gloves during the exercise....
One old Sheriff I used to work for- not as a Deputy- got his departments' .38 and .357 ammo reloaded using jail trustee labor, a process that seemed iffy to me, but he never had a problem during the 8 years he held the position, and his deputies could shoot. I got free ammo too, so I didn't complain too much. Ammo for semiautos requires a little more care and precision though, and in a semiauto handgun I'd rather prepare my own, thank you very much.

KKM, Jarvis and Bar-Sto all make very nice replacement Glock barrels, and there are a couple of other possibilities. I once considered going the .357 SIG barrel route with my own Glock 22, but it got replaced with a new Glock 17 instead, and I have no regrets thereof.
