I've held - no fondled - these a number of times at a couple of gun stores.
Years ago I had a Llama .22 clone 1911 that I loved/hated. It was beautiful and completely, totally unreliable. I can't even remember what I traded it away for, but it's long gone.
I currently have a Beretta 21A that I love, and it works flawlessly with everything but anemic subsonic ammo. It's not a 1911 style, and that's ok. But a 1911 is so classic. It was the first auto pistol I ever saw way back in boot camp.
Man the Browning is expensive, though. If it was $400 I would probably fall all over it just because it's so pretty. (I know, $400 for a .22LR borders on diagnostically committable.)
So, I haven't bought one yet. But I look at it every time I'm in the store. And I see that they aren't moving very fast, which sort of hurts my heart. I perceive the Browning to be every bit the "Gun Jewelry" that my Beretta 21A is. And I suspect the slow sales will eventually lead to cancellation of the model.
And I suspect that the high cost is because of manufacturing costs, not marketing greed. But if Browning could somehow make it sell for $400 I think they would sell like hot cakes. But at the current price I think they're just not going to make it. $500 buys you a lot of real gun to stack up against a .22LR.
One possible suggestion I could make to Browning, and a lot of guys will disagree, would be offer the barrel with a 1 in 9" twist for 60 gr SSS ammo right from the factory. If you look at the terminal ballistics of that much slug the .22 ceases to look so anemic in comparison to everything else. It becomes a hamster gun instead of a mouse gun in the self defense arena.
