Advice: Own G23 gen4 -How to: shoot 357sig? G32 barre?; new springs? How to: 9mm??

Should not? Maybe so.

As for accuracy, if you look at the position of the barrel of ANY caiiber Glock when the slide is in battery you will notice that the barrel is drawn FIRMLY down to the 6 o'clock position. Using a Glock 23(40 S&W) for simplification, the 40 S&W barrel will have a small crescent over the top where the barrel is pulled away from the top of the slide. Using a .357 sig barrel the lockup position will be identical since the barrel wall of the .357 is thicker to match the external dimensions of the 40 S&W barrel. With a G19 barrel in the G23 the crescent at the top will be VERY SLIGHTLY larger. The 9MM barrel is indeed narrower than the 40/.357 barrels outer diameter. However, the 9MM barrel will also be seated firmly at the 6 o'clock position and will NOT wiggle. THe lockup pulls the 9MM barrel down just as firmly as it does the 40/.357 barrels. The only accuracy issues will be a lower point of impact at greater distances since the barrel is 0.5 mm narrower (lower in the slide). 0.5MM? Yes, a 9mm is 1MM narrower than a 40 S&W(10MM) so half that is the radius difference of the barrels size.

Now, as for excessive wear and tear...

The rectangular slide is milled from a single block of ordnance-grade steel using CNC machinery.[32] The barrel and slide are treated with a proprietary nitriding process called Tenifer. The slide and barrel undergo two hardening processes prior to the Tenifer treatment, applied in a 500 °C nitrate bath.[31] The Tenifer finish is between 0.04 mm (0.0016 in) and 0.05 mm (0.0020 in) in thickness, and is characterized by extreme resistance to wear and corrosion; it penetrates the metal, and treated parts have similar properties even below the surface to a certain depth.[33] The Tenifer process produces a matte gray-colored, non-glare surface with a 64 Rockwell C hardness rating and a 99% resistance to salt water corrosion (which meets or exceeds stainless steel specifications),[32] making the Glock particularly suitable for individuals carrying the pistol concealed as the highly chloride-resistant finish allows the pistol to better endure the effects of perspiration.[33] Glock pistols with their Tenifer treatment are more corrosion-resistant than analogous guns on the market with any other type of finish, including Teflon, bluing, hard chrome plating, phosphates and other alloys.[33] After applying the Tenifer process, a black Parkerized decorative surface finish is applied. The underlaying Tenifer treatment will remain protecting these parts even if the decorative surface finish were to wear off.[5]

Let's just say I ain't worried. I can't afford enough ammo to REALLY risk damaging it.
