I for one don't understand your choice of calibers . You state you want a serious target revolver . What discipline do you compete in ? I'm a bullseye shooter & frankly your choices don't make a great deal of sense to me . I'm trying to help here so I need more feedback from you as to what you wish to accomplish . For most serious ( best accuracy ) work I'd consider other calibers personally as I'm not aware of a 9mm revolver capable of what I'd consider target accuracy . Yes a 357 can be quite accurate as can be a 9mm , but generally they've more recoil ( 357 ) & a lot of PITA loading requirements ( 9mm ) to reach their potential . For a stock revolver I'd consider 22LR , 32 S&W long , 38 special or 45acp . A S&W K22 , Manurhin , Colt OMM , S&W K38 or a S&W 25 / 625 ( stock guns ) would be my considerations . Other disciplines = other choices . For a 9mm to give it's best @ 50yds one needs a slower twist than factory barrels , 32 S&W needs a faster twist , 38 special with 148 HBWC needs a faster twist although the Colt with it's 1 in 16 is better than S&W 1 in 18.75 . Both the 22LR & 45acp shoot just fine with factory twist . A whole lot of considerations depending on your intended purpose . If you shoot at shorter ranges that's OK & you've less to worry about .
