Hello all,
I am a longtime reader of the S&W Forum, but only recently have joined as a member. I come to you today looking for information on a 637-2 Airweight that I received in a trade deal. It is used, included the gun only, no box, case, or paperwork, and I did not notice at the time of trade that the previous owner had taken steel wool to the entire gun and removed nearly all of the finish. Regardless, it still looks decent, and as I intend to use it as a carry gun, looks aren't all that important to me. I was hoping that the collective knowledge base here on the forum could help me date this revolver, and/or let me know if there is anything to look out for as far as durability issues or other problems. I have never had an aluminum frame revolver, and I would really like to know if there are things to look out for with these guns. The serial number starts with the letters CJA, and if I understand the serial number system for S&W guns, this is the necessary bit to determine a rough year or month of manufacture. I did consult a copy of the Standard Catalog of Smith and Wesson, (I don't know which edition it is, but is available in Kindle Format from Amazon.com) and I found that the serial number list ends in 2004 in the CHs.
I did get a chance to shoot it today, and I definitely like it a lot. I find that it has decent accuracy and consistency, with less felt recoil than I expected. I may have the Pachmayr grips to thank for that. This is the first S&W revolver and only the second S&W handgun that I have owned. It will definitely not be the last.
My test target from this morning's trip to the range: 10 shots at 25 feet. The two holes at the top of the target were from me getting used to sighting the gun, the rest found their mark fairly easily. the 10th shot was a double tap. Today's ammo was 38 special, Hornady 148 grain hollow-base wad cutters.
