Hi guys...

I am looking for an exploded view of either the model 40 or 42 with a parts list as well, or just the exploded view will do, if anyone has a MS word doc, a PDF or a Jpeg etc. that there able to email me, or supply me with a link or scanned copy ill forever be in your debt.

I emailed the boys at S&W and i was told that due to civil liability issues they no longer supply this stuff.

Please help !

my email is [email protected]

Please if anyone can help, were pretty useless and have limited resources here in South Africa. Thanks a million guys, its much appreciated...

Hey andy
I sent you an email with the scans you are looking for. mI hope they will help?

Wow, thank you a million for the scans, it was above and beyond, and it is much appreciated

If i may be so bold as to ask one more question, i am assuming that you have a model 40 or 42 S&W?

If you refer to the exploded view and parts numbers, there is a question that i would love to ask if you can give me an answer, i will have a model 40 and a model 42 for my collection, but then i have a second model which i do want to use for carry, i was wanting to disable the lemon squeezer in the model and it seems that S&W have catered for this with the part number 45 which, if you refer tot the diagram can be moved from the position in the frame to be used to "pin" the safety back strap or lemon squeeze lever to the frame, this should act as a way to disable the lever, is this correct?

If you have refereance to a user manual for the model 40 / 42 in PDF format etc. i would also find this most usefull, the 40 / 42 are unique in that none of the other Centennials have that same lever so a user namual for them is useless when one wants to know specifically about those parts.

Thank you for your help so far, it is most appreciated oe if you have pics of your model 40 / 42 id also kill to see them

I collect j-frames, and have so far the models:

36
37-2
38
38
40
42
49
49
60
342 Ti

and i plan to get models:

442
640
640-1
638
642
649 &
940

i will not stop till i have all these beauties in my collection

43
and a nice 2" 63?

Andy - with the origional 40 and 42 models, there was a pin included that lived inside the grips that can be installed in a hole in the frame once the lever is depressed. Many pins were lost when grips were taken off, but it is not something hard to duplicate.

Thanks Ken, would you advocate doing this, or should one leave the mechanism as it was origionally intended, if i use one of these for defense? the better of the two that i have in a duplicate model will be left as it left the factory, unpinned and the "lemon squeeze" left to work as intended, but for self defense, seeing that the model 40 and 42 are as the other centennials and have to be shot DAO, then what is the point of the back strap in a self defense senario, did Smith not realise this, hence the dropping of the back lever?

The real issue with the grip safety on a 40/42 is how it fits your hand. If the grip safety disengages EVERY time you grab the revolver, you should leave it functional, even (or perhaps especially) if it is a carry gun. If it doesn't disengage every time you grab it, you should pin it disengaged. That's what S&W gave you the pin for. On the recent reissue of 40's, I understand that there is no pin option. Therefore, you should try grabbing the gun and pulling the trigger a few dozen times to see whether it disengages every time. If it doesn't do that, or you can't test it, you probably shouldn't buy the gun. I say "probably" because perhaps you may already have sufficient experience with 40/42's that you feel you can make a decision without extensive testing.

Your results may vary with the grips. Many years ago, I found that the safety's disengagement was slightly unreliable for me with only the stock Magnas, but was 100% reliable with a Tyler added. It was also 100% reliable with what I believe were called Secret Service grips, once sold by Brownells. Nowadays, disengagement for me seems reliable even without the Tyler. I'm not sure of the reason for the change.

Obviously, testing for this is important, unless you simply don't want a grip safety in the first place. I do, and am very glad to have it on a Centennial.
