Owned one in 10mmK (aka .40 S&W) LOVED it, miss it, made the mistake of selling it for too little. It IS the "Acura to Honda" if Glock was a Honda. That said..
- The barrel IS conventionally rifled (i.e. with lands and grooves).
- The chamber is FULLY supported, moreso than most. If anything, I'd call it even "Completely supported".
- The chamber itself has more sidewall and top material than most guns I've seen. I'd look into the manual as to whether they consider it proofed for +P. I know the 9mm is technically "9x19mm", which IS the NATO round, and supposedly up near American +P pressures. Again, research.
- Given that it is a European make, it may have what I call the "Euro-chamber". These have a little step in the chamber right up near the case neck/throat area that makes for a tight fit if your brass isn't kept to length or isn't crimped correctly. Shine a light from the breech end while looking in to see it. I've only seen it on my Walther PPS, but an ArmaLite AR-24 and Ruger SR9 did NOT have the little "step" to it.
The frame is all steel, well-made. The ejector sits far back in the frame, and the newest models have a strong extractor - meaning that it tends to pull brass far back before kicking it off the slide - leaving room to not ding the chamber mouths.
If anything else comes to mind, I'll be sure to note it.
If you're looking at getting into lead shooting, there's a wealth of information out there. Just ask around - but warning, lead-shooting is a different animal from jacketed. The bullets are MUCH more sensitive to deformation, and accuracy needs much more care per round to achieve. Also, make sure you clean the barrel COMPLETELY of one bullet type before shooting the other.
Good luck, and enjoy!
