Keep an eye on CDI Sales on Gunbroker. They had a bunch of 5926s and a few 6926s for sale over the past year. They get regular shipments of surplus guns from Israel, so you may get lucky and they'll have a few more.

I want one of the very, very rare 5906TSWs with the integral rail. They match the configuration of the CHP 4006TSWs that are all the rage right now, but they're in a much more likeable caliber. As I understand it, there are no more than 100 floating around, so I'm unlikely to find one.

I'll settle begrudgingly a for CHP .40S&W, but if any of your have one you're getting rid of (and I know a few people here have them), let me know.

A 639 and a 3906 are also on the list, though they're a much lower priority.
