I just disabled it on my 637. I did mine by taking the so called "Flag" part outa the gun and grinding the stud off that actually locks the hammer then reinstalled it. Now I don't have to buy the plug or worry about the remaining portion of the IL getting in the way of anything. IMO, it's the best way. Only by way of a function check, or word of mouth would anyone know it's disabled.
Here's a pic of the flag with the stud removed.
The top portion is where the stud should be. That's the part that rides in a channel of the hammer and when the key is turned to the left forces the stud into it's locking position.
