I can understand having a sour taste after a couple of back-to-back unsatisfactory experiences with a gun company. I had that happen to me with a couple early production Charter Arms .44 Spl Bulldogs. I've not tried another one since, but I realize my avoidance of them probably isn't justified by such a small sampling.
I've been a Ruger enthusiast and owner since I was a young man. Lots of them. I learned to shoot using them, and the first centerfire revolver I bought when I turned 21 was a New Model .44 Magnum SBH (first year of the New Model, if I remember correctly).
That SBH had to go back for correction for a jumping cylinder base pin (revised after I bought mine).
I've had to have several Ruger firearms repaired or corrected for minor problems. Most of the during the 70's-90's. I've had them replace the trigger group, cylinder & hammer on a RH, and a slide was replaced on a P90 (heat treat problem I was told), a burred part causing the cylinder to occasionally seize on a SP101, a failure-to-fire with a MKII, and some minor issues with a couple of Security-Six series guns, a Blackhawk, etc.
I think I only own 10 Ruger handguns at the moment (off the top of my head), as I foolishly let many of the other ones slip away over the years.
The only new Rugers I've bought since the 90's have been a couple of LCP's, so I have no idea if their QC may have sometimes slipped a bit since then. Of the 2 LCP's I've bought, one of them had a walking takedown pin, but the new pin Ruger sent me corrected that minor issue. The other one's been normal and good.
Ruger is a fine American firearms company, but I'd not be surprised if the huge demand for firearms has made it harder for them (and everyone else making firearms) to prevent an occasional issue from making it out the door.
I'll probably buy more of them at some point, and without any more qualms than was the case many years ago.
Nice looking 625PC, BTW.
