Then Buckmark is noisy, the bolt is open on both sides, resulting in a strange metallic clank every time it cycles, plus it blows debris back in your face. The Ruger does neither. Ruger offers several easily available threaded models, the Browning only comes in one factory threaded model, and I have never seen one available anywhere. If you decide to buy the Buckmark, unless you get lucky and find a unicorn factory threaded model, you are looking at $300ish for a Tac-Sol threaded barrel.
The S$W 422/622/2213/14 IS a good host, but is difficult to find. The factory adjustable sight models didn't have enough adjustment in the rear sight to truly zero them, so you are better off with the fixed sight model, as long as it shoots to POA. The 2213silver, and 2214black are cool little pistols, but very hard to find, have fixed sights, and are expensive. Figure on $500 for either, IF you get lucky.
Surprisingly, after my recommendation for the Ruger, my next two favorites are both generally regarded as inferior pistols because of the Zinc alloy construction, but they both offer very low action noise. They are the Sig Mosquito, and the Walther/Umarex PPK/S replica. Both come threaded, or as a threaded model, are inexpensive, accurate, and fun to shoot.
