While I haven't used any lead loads in my 1006, I can assure you it has not jammed.
I'm well aware of Glock's excellent record for reliability.
However, their ease of use can be a drawback when your life is on the line. Any dummy that takes the gun away from you can easily use it against you. The safety setups on the 1006 or the 1911's make this harder to do. BTW, my 1006 has had it's magazine safety removed so that it will fire if the magazine is lost. That might be something you may wish to consider.
The other thing about Glocks is that they have been known to come apart, never to fire again, if they get tossed or get used as a club. Something the 1006 and the 1911's don't have for a concern.
Like alot things, selecting a pistol is accepting a few trade offs. I don't like the DA feature, for instance, on the 1006. If I ever find out that S&W is doing their single action conversions again, off it goes for the conversion. E
