I have a S&W Model 37 Airweight. Can anyone tell me which parts in the M-37 are the same as the M-36? My 37 was manufactured between 1979 - 1980. The serial number is J6959xx.

Thanks for your help.

I believe all parts from the trigger line, trigger, rebound sping and block, cylinder stop, and main spring are all the same for common frame sized revolvers. So any J frame model will have parts that can fit any model from the trigger line and down..all5x

Need to restore the bluing on a model 37. Any help will be appreciated. Thanks.

Hola, kurios. Welcome to the Forum. Que' fue? The airweight 'blue' gun does not have a blued finish frame like the steel models, but an anodized 'aluminum black'. I don't know how far your finish is gone; 'blued' 37 models normally show finish wear/thinning on the frame edges and corners.

Birchwood Casey used to offer an 'aluminum black' touch-up solution in a 4oz bottle, don't know if that will suit your needs. The cylinder, crane, barrel are steel and regular bluing will work on them.

Hope this helps. Co'lo suave!

I don';t think anyone recommends removing the barrel from the frame so that the aluminum frame can be re-anodized, due to the possibility of the frame cracking when the barrel is reinstalled. The odds may be against t, but I wouldn't want to take that chance. Ditto for reblueing the barrel. All the easily removed parts can easily be reblued though.

Everything except the frame of a M37 is the same as an M36

The M37 barrel is stamped "airweight" but otherwise I would say the parts are all the same.

Resurrecting this thread from the depths.

Can a Model 37 3" barrel be installed on a Model 36?
Assuming the 37 barrel has already been removed.
Thanks!

Yes, with the possible exception of an Airweight stamping the 3” barrels on a model 36 and 37 should be exactly the same.

I have a 37 with a crack in the frame under the barrel. Is this fixable. I am assuming it is unsafe to shoot. The gun has never had +p or hand loads and probably not even 50 rounds through it. I think it was due to over torque at the factory.

It's not safe to shoot w/ a cracked frame, nor can it be repaired. There are a lot of valuable parts that can be used in other guns.

The short answer is: NO. Sorry.

Depending on the age of the revolver, contact S&W. They MIGHT give you credit towards the purchase of another handgun. And, they might not.

Thanks for the responses on the cracked frame. I will probably keep it around as a parts donor, if needed. I have heard that Smith will not return it if they don't cover it under warranty. I have asked them and they will not answer the question so I assume it is true.
