Slidemuzik,
There is no rust anywhere on this gun. From what i have found out all of the slides for this model were out of stainless. There are several grades of stainless and some will rust with time.
The numbers on the box do match the gun. At this time i am looking for 600.00. below is a little i found out about this gun.
I think 600 is the minimum it would take to get my attention, but I'd have to like them.
The next small-caliber model was introduced in 1987, the Model 422. Two versions were made: the Model 422 Field with a fixed sight and black plastic grip plates and blued finish, and the
Model 422 Target, with an adjustable rear sight, walnut grip plates, and a stainless steel finish.
This doesn't seem correct. I believe all 422's had a "blued" finish. 622's had the stainless finish.
In 1996, the Model 622 VR was introduced. The “VR” stands for “Ventilated Rib,” and refers to the sighting rib above the front portion of the slide. The Model 622 VR has an alloy frame and an adjustable rear sight. Most have black plastic grip plates, but a few were built with walnut grip plates.
Only 6-inch barrel versions were made,
This isn't correct as I am intimate with a 4.5 " 622VR. See this thread for some good info and photos. http://smith-wessonforum.com/smith-wesson-semi-auto-pistols/316801-622-vr-rescue-thread.html
and no provision was ever made for a 12-round magazine. Within months of being introduced, it was withdrawn. For game purposes, it is identical to the Model 622 with the 6-inch barrel.
The Model 2206 was introduced in 1990 as a totally stainless steel version of the Model 622. It was originally available in 4.5-inch and 6-inch barrel versions, but only 6-inch barrel versions were made after 1993.
Three versions were built: the standard 2206 (identical to the Model 622 for game purposes); the Model 2206 Target with match-quality barrels and a micrometer rear sight, and the Model 2206 Target Match with an ergonomic grip, adjustable hand support, micrometer rear sight, and heavy match barrel. Production of all 2206’s stopped in 1996. This is very interesting. I am only aware of one 2206TGT. 6" barrel only. Millet adjustable sights. I have seen several grips. 2 carved walnut target style (Herritt made some) and I have heard there was a plastic target grip, but don't recall ever seeing one and can not confirm this. The adjustable grip is new to me. Where did you find this info? I'd love to see one.
