WRT the sights... The new ones have completely different sights from mine. If you think the old ones suck, you might like the new ones.
WRT the price... Ruger has been raising prices on a few guns, and they're pricing themselves out of sales volume. The 10/22 is now priced too high as well, though $50 here or there might not be as prohibitive. I wonder if some of their dead models would be around still, if the prices were sane. People who have them really like the PC carbines, but they were too expensive. And the Deerfield was a neat idea, but for less money, you could get a
stainless 1894 with a beautiful checkered walnut stock, and it holds more rounds and has a lot more aftermarket support.
WRT the magazines... I've heard that a factory follower will solve any issues. I have yet to try it. I have one candidate; the other mags I have work fine. Aftermarket follower changeouts are common in the AR world, so I wouldn't say this is a showstopper. OTOH, a modification to allow AR magazine use is WAY overdue. Remington did this with the 7615; I'm sure they had a good reason. Hello, Ruger?
WRT Bill Ruger's words... He's dead. At this point, Ruger has good reasons to sell 5-rounders. They managed to escape the last AWB, as well as the laws in California and elsewhere. I'm sure they're just trying to keep their guns from being banned. As a Californian, I have mixed feelings about this. However, I've been able to buy a Mini-14 here, without interruption, through all the laws they've passed. Is that bad, or good? I wouldn't have been able to buy a decent .223 carbine at all a few years back, except for Ruger's steering clear of bans.
I own 3 Rugers. I have mixed feelings about Ruger politically, and I have mixed reviews for their guns. I have a much lower opinion of the 10/22 than most people seem to. It's probably the first gun I'll sell to make space. My 22/45 is flawless. The Mini is not target-grade accurate, but a well-made power tool. I can hit targets like water bottles at 200 yards; it's a helluva plinker and a functional defensive carbine. But when I bought it and took it to the range, I was disappointed. At the time, I didn't know any better.
I have 4 aftermarket magazines that I've used. Only one of them gives me any trouble. It's getting a factory follower, when I remember to buy one.
