I think using uncoated lead bullets these days is kind of silly. You can buy the kits and do it yourself if you want to cast your own but at the prices they charge (Missouri Bullet Co, & Acme Bullets off hand, there are others) it's not worth my time to even fire up the lead pot these days!
I got some of the MBC coated 140 LSWC gr bullets to try in my Glocks 29 and 40 (10mm) and they worked just fine. 6.0 of WW231 barely worked the actions (I have heavier springs in both pistols) but 6.5 to 7.5 worked perfectly. MBC says these bullets can be fired at up to 1500 fps so you can use other powders to get higher velocities if desired. Both are stock barrels and have shown zero leading. I also use the coated bullets in .45 and 9mm, again with zero problems. I've shot a bunch of lead 115 gr 9mm bullets thru my Glock 26 without any problems as well... BUT! You have to stop shooting after the first 50 rounds and visually inspect the barrel for leading and every 50 or so rounds after that to be certain. If you have any leading at all, just fire 6 rounds of jacketed ammo to smooth it out! Shooting jacketed *does not "blow the lead" out of the barrel* but it just smoothes it out so it's not a problem, pressure wise. If you get any leading in the first 50 I recommend either not shooting lead at all or using a barrel smoothing kit such as the Nico kit before using any more lead. My Glock 26 barrel simply does not lead much at all and I've shot as many as 250 rounds in a session without problems. But remember, every barrel is unique and some simply won't tolerate lead bullets at all, period! Even hard cast can cause some leading. For these barrels you're stuck loading jacketed or at least plated bullets. Fortunately, these barrels are far and few between!
If shooting lead bullets out of your Glock, just check it often and it's perfectly safe. If you end up with lumps you didn't check often enough and need to stop and clean the barrel with a bronze brush (the only thing, other than abrasives such as JB Bore Cleaner) that will actually get the lead out of the barrel. DO NOT ATTEMPT TO SHOOT LUMPS SMOOTH! That's where you're likely to blow your pistol into pieces... and maybe your hand! The only chemical cleaner that actually works is the Outers Foul Out electro plating kit. I have tried every other chemical that says it will remove lead and they all flat out lie! Mostly they rely on a layer of copper under the lead. If your barrel is clean, it's a waste of time and money!
