Can't you shoot plated ammo? Is there a barrel with ploygonal rifling available for the M9-1A?
Yah, the above comment is exactly right. You can shoot whatever you want. Lead bullets are fine. Reloads are fine too. Personally I don't see a lot of commercially available 9mm that isn't copper jacketed. In the stores I frequent, generally all that is available in 9mm is Remmington metal case, Remmington leadless, Remminton hollow point, Winchester FMJ, WinClean, American Eagle FMJ, and sometimes some stuff by Speer or Fiochi - all of which is copper jacketted. I'd be interested in trying ".22 LR"-style lead bullets in 9mm, but I haven't seen anything like that in the shops.
The point I was trying to make - not very well - in my earlier post is that the rifling in the Steyr is a fairly pronouced version of the land-and-groove type, and it takes longer to clean. With a Glock with the hex rifling, I find I can get it clean almost just with a couple of patches and a little brushing. I usually use some Wipeout and try and get it really perfect, but that is just because I am a freak when it comes to cleaning my guns. It's not necessary by any means. But with Steyr it takes a bit more time and work. I try and get the grooves cleaned out completely, so I let some Wipeout sit in there for several hours - sometime over night, then wipe it out with a patch, then use a brush, then patches.... etc.
The Steyr is a little more work, but I do find it to be somewhat more accurate than a Glock when it is properly cleaned-up and maintained - but just slightly. Glock is an accurate gun too and whatever difference there is between them probably has more to do with my own shooting style and maybe the lower bore-axis than the type of rifling.
