There are millions of the Ruger Mk I and II pistols. I'm excluding the pre-Mk Is as they tend to be a little pricy due to the collector value of those early Rugers, and I'm excluding the Mk III as Ruger added a Loaded Chamber Indicator (LCI), a Key Lock, and a Magazine Disconnect, that many people do not like. The positive with the Mk III is that the magazine release is on the side of the grip like a 1911, rather than at the heel like a P08 Luger.
The 1 millionth standard Model came off the production line in 1971, and when you include the 5 1/2" bull barrel Mk I Targets and tapered barrel 6 7/8" Targets that were made from 1963-1981, you're in the neighbor hood of 2 million pistols. Subsequently, Ruger made over 3 million Mk IIs between 1982 and 2005. That's about 5 million pre-magazine safety pistols floating around out there, and you can find a Mk I or Mk II in excellent condition for about $300, and the standard model will sell for a bit less.
Then you've got all the later Mk IIIs as well as the polymer gripped 22/45 pistols that have a 1911'ish grip angle.
The point here is that you can get an excellent Ruger Mk I, Mk II (many people regard the Mk II as the peak of Ruger .22 LR pistol development) or Mk III for a lot less than you can get a new Ruger Mk IV, or another new pistol with similar capabilities such as the Browning Buckmark or S&W Victory Model.
At present, if you want a Mk III you can find them brand new in the box at nicely discounted prices given that it's been discontinued in favor of the Mk IV.
The Mk IV has the features of the Mk III but in a hinged receiver design that is easier for most people to dis-assemble and re-assemble, but it loses the nice lines of the Mk I, II and III.

In terms of the triggers, the Mk II triggers were generally better than the Mk I triggers, which were generally better than the pre-Mk I triggers. However, a Volquartzen trigger and sear kit for a Mk I, II and III will cost you about $75 and isn't too difficult to install.
A Mk I or Mk II with a new trigger and sear will give a S&W Model 41 a run for it's money in a Bullseye match at a fraction of the cost.

I have no experience with the S&W Victory model 22 LR pistol. But my preferences in S&W runs to their excellent Model 17 K-frame target revolver. The trigger is excellent and it's a 1" at 25 yard revolver with match ammo, and still only about a 1.5" at 25 yard pistol with plinking ammo.

The Mk I T678 and the Mk II Target shown below together cost less than the S&W Model 17, but all three are great .22LR handguns:
