I agree with all who say that small frame geometry is handicapped vs large frame geometry, and rimfires need a firmer strike than centerfire to be 100% reliable, within the reliability limitations of the rimfire ammo itself, of course. But that is no excuse for accepting small frame DA triggers a lot worse than they need be.
Clean, lube, dry firing, high round count usage tend to help all of 'em, but those who begin life "better" are pert near guaranteed to stay "better" post all such improvement efforts, when done same/same.
Polishing parts may yield a better short term feel (or at least less gritty, less binding), but if/when done on a gun which is simply of poor fit using 2nd rate components, it is, at best, a dubious "solution", and too often translates into deliberately introduced premature excessive and undesirable wear. The only "good news" in that, is that very few people will ever really wear out any half-decent 22 rimfire revolver by merit of round count alone. Far too many do get damaged via neglect or abuse.
Lighter mainsprings and (more often overlooked) lighter return springs can yield a lighter trigger pull, but is no guaranteed solution either. Not even consistently so for individual guns of exact same make/model. Worth a trial, though, so long as you are aware of the possible light strike and reset issues that can result.
But getting better quality parts, fit, and finish never was a free ride, else we would all own a safe load of Freedom Arms SAs, mint condition original Dan Wessons, mint custom shop S&W k-22 masterpieces, custom shop Pythons, and Korths. I don't, most don't.
You do not always get what you pay for when you pony up the premium price, but you can almost always expect to get what you pay for when you buy cheapest available product. No guarantees, either way, but reasonable expectations do tend to follow common sense. If it walks like a duck and quacks like a duck....
If a shooter cannot afford the premium price, fine, do buy whatever you can afford, do what you can do with it, do enjoy shooting it whether it be a Heritage Rough Rider, or a Hi-Point or whatever. They may not be real pretty but they do go bang, and (outside of formal competitions) most firearms, new or old, are capable of better accuracy than most of the hands that hold them, leastways my hand.
There are, alas, some few exceptions. The bad news is that they cannot be identified up front by price alone, nor by brand alone.
But when it comes to DA revolvers, I myself have zero interest in a gun that shoots well enough SA, but has a crappy DA trigger. I have other guns to shoot SA only; I buy DA to shoot DA. More to the point I buy SA/DA to enjoy shooting both SA and DA.
I also have zero intention of ever buying a NIB gun to send to a gunsmith or buy aftermarket parts for, simply to make it "acceptable". If/when I travel that road, I would start with the best quality gun I could stretch my budget to, and then try to get on Grant Cunningham's waiting list. If a ~$300 NIB gun needs a gunsmith, I try real hard not to buy it.
good small frame triggers are a challenge, particularly yes they are
but supposing that all are bad, or supposing that all are equal, is just plain silly
Anybody who cares about small frame 22 DA trigger quality re: current NIB manufacture need not pay attention to any of us here anyway. Just find a good gun shop that stocks new S&W and new Taurus (and probably new Charter) small frame rimfires, and pull the trigger DA on every one of 'em. The differences will be obvious enough.
Same can be said of small frame centerfires and snubbies; you really need pull the trigger for yourself, and decide for yourself if the difference in feel justifies the difference in price.
But buying any firearm with expectations of having to turn it into what it ain't, is about the same as marrying some gal or guy on the thesis of turning them into what they ain't. Don't bet the farm on it.
Me, I may never stretch myself to the price of a "near mint" 651 to match my "near mint" 63, but I have picked up way too many of the NIB 94/941s in my own hand to throw down $300 on one of 'em. I will leave 'em for those that love 'em.
I do need to find the most recent reincarnation of the Charter though, to see how it feels in my own hand. Some few posts here on THR suggest worth a good hard look.
PS
not all full size frame 22 DAs are "really stiff" even with factory springs
most S&Ws (new or old) are actually quite good, and some of the older model Taurus k-clones were as well... short sight radius and too light weight is not shooter friendly, but the guns themselves "can do"
not all DA 22 revolvers are difficult to shoot well, most with half decent triggers are pretty easy to shoot DA well, brand loyalties notwithstanding
many shooters do not shoot them real well in DA, true, but then many shooters claim DA centerfire simply cannot be target shooting accurate (in some part because too many who target shoot DA insist on s-l-o-w-l-y staging the trigger in an attempt to pseudo-simulate SA, and they out think themselves, whilst waiting to feel the breakover)
taurusarmed.net just might not be the most objective possible source on Taurus guns
Same goes for Ruger forums on Rugers, or S&W forums on S&Ws, or Colt forums on Colts, etc..... you decide, but if you read one, you know, read 'em all
pull the triggers before you buy, decide what you can afford, and you will likely be happy enough with whatever you choose
