He probably wants a 40 because the 9 is a weakling compared to it. the 40 has nearly the power of a 357 Mag. JMHO. I would think for only about $125.00 difference between new and used a new would be a better deal. A friend of a friend had bought a used Glock in 45 ACP. Don't know just what model but back to the story. No manual or other info. Well they were shooting it with lead reloads and yes it blew up no injuries except for messy underware. Then came the info search and they found out you are not to use plain lead bullets. I assume this is true with all Glocks. Just thought I would pass on this little tid bit. Bill
If one blew up using lead bullets my bet would be on insufficient crimp (taper only should be used and not enough to squash the bullet but enough to withstand about a 30# push) allowing the bullet to telescope into the case on feeding causing an extreme pressure spike. Common thing in autopistols, especially if you don't sort cases, test the crimp, and don't use a hard allow bullet. I've got a blown out 9mm case that I believe this happened to.
After seeing some of the prices listed it picques my interest and will check the prices out tomorrow. We normally mark our guns up twelve to fifteen per cent for guns under $400.00 and ten percent for guns over $400.00 so I would be greatly surprised that our prices would be that far off. Most guns have gone up nearly 15 percent in 2008 and I just placed my annual qualifying Benelli order and they went up and additional ten percent. Jackie B.
Skybuster and EE You got it right on the head. The polygonal rifling caused a build up and bingo the blow up. Yes the warranty is voided using cast lead bullets. If the person in question would have gone online and downloaded a free maual all would have been okay. However he was in a hurry to try out his new toy and bang a blowup. As far as no safety, well they are just as safe as revolver if you don't pull the trigger. Same buch of rounds loaded by the same fellow ran jsut fine through 1911's on the same day and no there were no double charges of powder. I shoot the same fellow's reloads all the time and never a problem. It was the lead in the Glock barrel that caused the problem. I only posted the story to warn others. You can buy conventional rifled barrels that are a drop in for Glocks so you can shoot cast reloads. By the wasy the XD has the same type of trigger set up as the Glocks with the addition of a grip safety. Bill
The barrel leads up with cast bullets. Causes an overpressure and will blow the bottom out of a .40 case. The chamber of a .40 Glock is no more less supported than most other guns. Problem arises when you start playing with 9mm pressures (high), 180 grain bullets (heavy), and a leaded up barrel (resistance). Think of loading 1 1/2oz lead with 25 grains Red Dot.
People in the know do not recommend reloading .40 period.
I have a Glock 22 and my brother in law has an XD. We both like the Glock more hands down.
