I also voted for the Ruger. As has been stated there is a host of accessories available for the Ruger to allow the user to "have it your way".
The newer MKII's made and the MKIII's come from Ruger Drilled & Tapped for a scope rail that attaches to the top of the receiver in front of the rear sight. It is a matter of getting the optic you want, a set of rings, mount the optic and sight it in. Yes it is that simple.
On the other hand I choose a Burris Fast Fire Electronic Red Dot Optical Sight. The sight is not a lot bigger than the rear adjustable sight that comes on the Ruger Target Models. I used the Burris Mount that fits in the dovetail that the rear sight fits in (yes the rear sight needs to be removed) and it makes for a compact package.
I also added the following parts:
Volquartsen Custom Target Grips
Volquartsen Custom Extended Bolt Release
Volquartsen Custom Target Sear
Clark Custom Gun Steel Ruger Trigger
On Target Guns Blast Shield
plus I polished the Factory Ruger Hammer
I have been involved in Bullesye Shooting at a local indoor shooting range since 1990. I have had Rugers, S&W Model 41's, S&W Model 2206's, S&W Model 22S's, Browning Buckmarks, plus a few I probably forgot.
The Ruger MKII in the above photo is the most accurate .22 LR Handgun I have ever owned bar none. Plus it holds a very special meaning to me as it was purchased new by my late brother. After my brothers passing I bought it from my sister in law and decided since this was a special Ruger (special to me anyway) that I would customize it to better suit my needs. However with all the customizing I have done it does not shoot groups one bit tighter than when it was original, it is just now a lot easier to shoot.
The thing with Bullseye Shooting is that you are going to go through a progression as your skill level improves. With a Ruger and the fact that they are so easy customized with so many parts available both you and the handgun can grow together so to speak.
