The most reliable s/a target model under $1k that I've ever used is the S&W mod. 41, which can often be found on the used market. It is one of the finest handguns ever produced by that company. Since you didn't mention a budget, you could also look at the target models from Hammerli, which include the 208, 280, and SP20. Pardini, Morini, Unique, Feinwerkbau, Walther, Beretta and Benelli all make s/a models as well. The great majority of the models produced by these makers will probably cost more than what you will want to spend, but they are interesting to see, and worth some time looking them up on Gunbroker.com or similar sites.
