There are several that have about the same accuracy. Depends on what you want and want to spend. The P/C autos in 9mm all shoot great. Depends on what model you want and what you want to use it for. The single action guns are the easiest to shoot target wise because of the trigger and 5-6" barrel length. The 6906 and 5906(IDPA) models shoot just as well 1" or better at 25 yds, under 2" at 50 depending on the ammo you use, but are a little harder to shoot because of the sight radius. But they also have a use as a self defense/ IDPA, shooting school/ type of gun.
My favorite to shoot is actually a 5" 5906 (IDPA) type model that they did a short run of. The gun has enough weight it hardly kicks.
However these P/C guns are drying up quickly and prices are starting to sky rocket. The factory no longer makes anything in this type 5906/952 etc. and probably will not again at least at an affordable price.
It pretty east to make a 1911 type pistol shoot 1" or better at 25,some will come close out of the box 2" or so (many standard 9s will do this,SIG/some Berettas ,which might be plenty good for you. if you buy a standard make SPFLD or S/W with target sights, a custom fit bushing and/or link and /or after market barrel like Nowlin/KKM/Kart will do the trick.So standard gun, now 9-1000, 3-400 more for barrel work. Same 1400-1500. My friends and I have experimented for over 15 yrs or so, doing this for alot of new shooters.
The nice thing about the P/C guns is there are easy to shoot and maintain, much more that a 1911 format.IMO
So you have to decide what you want and then hunt for it. Im sure people here will help. Good luck ,Bob
