There are several owners on this forum, including myself. What do you want to know?
1. Is it reliable? Yes, unless defective or too much "improved." S&W has excellent warranty service.
2. Is it a target gun? NO, it is an entry level service pistol. It can be used in IDPA SSP competition. Power factor of 125 only is required of the ammunition.
3. Does it kick? Sure, especially with full power .40. I have a handload of 4 gr of HP38 behind a 180 gr Berry bullet that is a pussycat for IDPA SSP.
4. Should you immediately start removing or cutting springs to "improve" it? Well, if it is just to be a range gun, OK, but for a defense carry gun, probably not.
5. Are there lots of "goodies" for it like for the Glock? Not really. Plenty of holsters, though.
