I was given a Ruger MKIII 22/45 for my birthday last year and it is without a doubt my favorite handgun I currently or have ever owned. Mine is the bare bones model; 5.5 inch barrel, target sites, fixed grips. The only modification I've made is adding a HiViz front site, which cost around $30 off amazon. I was surprised to read so many complaints about...
Reliability - Mine feeds anything. I've gone through 1000's of the Remi gold bullets and I just finished a large zip lock freezer bag of mixed ammo of unknown age or origin. Other than primer issues, hardly any mis feeds.
Trigger - After a year of use the trigger is great. For someone like who does not compete, I'm not sure i require much more out of it. The trigger makes it easy to shoot the pistol fast and accurately.
Accuracy - For how I like to shoot, no rest and inside of 25 yards, the Ruger is great in the accuracy department. I'm sure that on a rest or in more capable hands, it's a tack driver.
Ergonomics - I was given the Ruger as a surprise and had never held before I was holding my own. I will admit that the grip felt a bit narrow to me but once I familiarized myself with it, I had no issues.
Controls - I'm a lefty so nothing is ever in have right place. I'd love it if the pistol could sling shot but its not for defense or competition so I'm not worried about.
I love my Ruger and I'm sure I'd like a Buckmark just the same. Maybe I'll get one of those next. Until then, this one is my favorite...
