Better positive reset on Airweights v. Steel J Frames?

[Pef]

If you have replaced rebound springs in multiple j-frames, have you noticed a tendency of the aluminum framed airweights to require less spring power for a positive reset?

I own a number of j-frames, ranging from 36 no-dashes to 60-14's and 640-3.

I also own a 637 and a 642 (both have the lock).

I replace the rebound springs in most of my "frequently shot" j-frames with lighter springs. I have rebound springs ranging from 11 to 15 pounds.

Most of the time in the steel j-frames a 13 pound rebound spring is a low as I can go before the reset becomes sluggish and I outrace the trigger. The one exception is my 640 pro which still has positive reset with a 12 pound rebound spring.

But for my 637 and 642, both still have a very snappy reset with just 11 pound rebound springs. Both triggers still have a firm pull and a nice snapback that can actually reset with no problem even with my finger riding the trigger.

One may be a fluke, but two?

So, did I just get lucky with both the 637 and 642 and get a couple of exceptional guns, or is this something you have noticed as well?

Thanks,
Pef

Every gun is slightly different - even within the same model number.

For guns you target shoot with ONLY then you can go as low as you feel comfortable with, but for guns that could be called upon to defend your life with I like to either stick with the Factory rebound spring if tolerable, and if not I will replace it but I NEVER go below 14 pounds. If memory serves I believe the Factory Rebound Spring is 18 pounds.

I've got some Target/Range ONLY guns that are light and smooth as silk but never carry them and never use them for home defense. I have a note in the box where the gun is stored that says:

"This gun intended only as a dedicated Range gun due to the fact that the springs and Factory specifications have been altered". There is a bag of parts to restore all factory settings and tolerances in the box as well. This way if anything happens to me whoever inherits the gun can quickly restore or have someone else restore it to Factory specifications.
