It's a fine firearm for IDPA SSR Division and on my to buy list.
For IPSC it's not the best choice. There is no barrel length restriction in IPSC, so the six inch S&W Model 625 is the preferred gun, as the short fat .45 ACP rounds are easier to load using full moon clips than the long skinny .357 magnum.
If your country restricts calibers above .38 or military calibers then it is a good choice for IPSC.
It will also be at a disadvantage for ICORE where there is no maximum round count, so the 627 or the 686 Plus have the advantage in that game.
