I'd have to disagree that newer Rugers don't need any work on out of the box. I've worked on a bunch and while they are tough as a tank they are, on average, far from perfect. I'd even go so far as to call them sloppily assembled to be honest. Too much endshake, oversized cylinder pin hole, barrels that are so tightly screwed on that they constrict around the frame then expand half way down the barrel and then tighten up again. Poorly fitted hands, burrs on the insides, poorly machined ratchet surfaces etc etc. They function quite well despite this and last forever but most of the ones I've had on my bench need a lot of cleaning up and tweeking to be where I would want them.
My own .38 NMV race guns have oversized cylinder pins, custom made cylinder bushings, new wider German silver front sights, machined rear sight grooves, Shotgun Boogie short stoke kits, Shotgun Boogie springs all round, modified firing pins and major deburrring and polishing of all internals. They are the most reliable and smooth handguns I've ever owned. Rugers make a good base gun to work with.
