Question on various S&W snub nose models

    I am trying to find out some information on the S&W model 642, 638, 640 and 649. I know some of these were chambered in both the 38 and 357.
    I have a early model 38 snub nose in a blue finish. It is in good condition. It is the SA/DA model.
    I am thinking of going to a stainless model in a snub nose. The models listed above are what I am considering.
    My question is - were any of the above listed stainless/alloy snubbies produced before the lock system was introduced?
    Also, on the model 38 that I have, will it handle 38 + P ammo?
    Any information would be greatly appreciated.:D

    I haven't looked your question up, and I'm certainly not an expert... But, it seems that S&W started production of .357 caliber J-Frames in about 1997 or so. The internal locks didn't come around until maybe 2002. So, there was apparently a period of about 5 years where .357 j-frames (60,640,649) were made without the internal lock. I believe the 638 & 642 .38s were manufactured during that period also. Before the introduction of the "j magnum" frame in 1997 or so, all the SS & alloy models you mentioned were definately manufactured. Only they were in .38 Spl. only and I don't think the alloy models were +P rated. As for your question about the "early" model 38... It is my understanding that +P should not be fired in ANY ALUMINUM ALLOY S&W .38 cal. unless, like the ones of relatively recent manufacture, they specifically state ".38 Spl +P" on the barrel. I don't think any of the S&W model #38s were ever made to safely fire +Ps. A quick phone call to S&W customer service will give you the definitive answer though. BTW... My own newest handgun is a brand new SS model 649 in .357. Except for not as many good holsters being available as there is for the conventional external hammer models, I love it! If I were going for pocket carry, I'd of course probably go for the lighter weight and hammerless 642 or 638 in .38 spl.

    DB - Thanks for the reponse.
    I have not been able to find any of the models that I listed without the safety lock, but it appears that they exist. Maybe people just do not want to part with them.
    I am not sure that the safety lock mechinism is really a problem. I just do not like them very much, and have read of a few problems.
    I will just stick with the standard 38's in my model 38.
    I will keep looking for a lock less, stainless snub nose.
    I will call S&W on Monday.
    Thanks again.

    ArchAngelCD - That is some great information. Thank you.
    Now all I have to do is figure out which model I want. So many choices.:confused:

    Well, if you are even the slightest bit recoil sensitive, I'd shy away from the airlite models.

    I am leery of alloy guns and warm loads but apparently "back in the day" both Elmer Keith and Skeeter Skelton did extensive shooting of alloy J frame Smiths (Keith used factory 38/44 ammo which was much hotter than +P and Skelton shot 2,000 rounds of +P through his test gun) and they reported no damage or undue wear.

    I really think +P is a mid-level load so my guess is that no harm would come from shooting it in a quality gun even with an alloy frame.

    Boy this topic comes up a lot. Wish I had a nickel...

    I recently bought a Model 638-3 and I'm very glad I did. A .38 +P round out of a 15 oz snub has a stout kick but nothing that's too hard to over come. With a little practice you can take a good second shot just as fast as you would out of a 4" barrel. I decided not to buy an AirLite because I shot one several times and DO NOT wish to shoot one again unless I have no choice. If you really want a .357 Mag short barrel then I suggest a 23 oz Model 60, 640 or 649. The extra weight will help with control. I didn't see the need for a Mag in a 2" revolver so I went for the 638. Besides, the 15 oz snubs run around $400, the SS Mags run around $650 and the AirLite Mags are near $900. (I KNOW, I know, you can get them cheaper but that's list prices) I just don't think the small increase of power the Mag round provides in a snub is worth all that money.

    Good luck on choosing a snub that will make you happy.

    This is my choice... Prelock 638 (Airweight Bodyguard), Light, smooth target trigger..... Add a set of Crimson Trace Lasergrips and you, IMO, have a super cc firearm...:D

    And for those times when you feel the need for pistol as opposed to a revolver, I suggest:
