If you run into a bear on the big side the 29 will be the better choice. That being said reloads are a no-no in the glocks unless you get a replacement barrel. I made the mistake of shooting some reloads from a reputable reloader and second round, kaboom! Blew the magazine out and magazine release, cracked the frame and hurt like the devil! Cost me $100 from glock to replace the frame. All that being said I carry my 29 in my truck daily.
Wait a minute there.
Lead
projectiles should be limited with a stock Glock barrel because they use polygonal rifling. That type of rifling can lead to heavy leading in a barrel. That's why an aftermarket barrel using traditional rifling is recommended for anyone who plans to shoot lead or hardcast lead bullets out of a Glock.
Reloading has nothing to do with it. Yes, some reloaders use lead or hardcast bullets when reloading, but it's the bullet type that can cause problems, not the fact that the cartridges have been reloaded.
If the second round of reloads blew up your gun, then that was clearly a double charged or overcharged round, and it doesn't matter if the rounds you were shooting came from a "reputable reloader" or not. There's no way two rounds of lead bullets could blow up a gun. It was clearly a double or over charge situation. So bottom line, whomever loaded those cartridges screwed up.
There's a reason that reloaders have a rule that states "
Never shoot someone else's reloads." You just don't know what mistakes they may have made.
Shooting reloads in a Glock, or ANY gun is perfectly safe if you yourself have loaded them with good methodology and care,
worked up the load for YOUR gun, and used published reload recipes with the same components. If not the exact same components, work up the load. If shooting the same cartridge in a different gun, work up the load.
If given reloads from someone else, pull the bullets and weigh them, dump the powder, and reload them with a powder charge you have data for,
and work up the load.
There are all sorts of copper platted, copper jacketed, and monolithic solids that are great bullet choices for 10mm auto and 45 acp both, and perfectly safe for a Glock be them reloaded by a guy in his attic like me, or made by a major manufacturer.
But if I hand you some reloads I made, you should not shoot them. You have no idea if I'm a competent loader, and even if I am it doesn't mean I didn't make a mistake.
