Storing 92FS cocked- Damage Hammer spring?

I don't have a safe or pistol lock box. Instead, I bought a 5/8" lockable cable by Kryptonite, which I run through the Beretta's wide ejection port. This leaves the hammer cocked and thus the hammer spring under tension. So I am now curious about hammer springs. How long do they usually last? Will keeping it cocked shorten its life much?
Also: How do I change the spring? It looks like you just unscrew the lanyard loop.

The cable will be WELL secured to prevent theft.
 
I wouldn't mess with the hammer spring if I were you buddy. It's a real pain to get back in under tension and last I heard, that particular spring will outlast many major components in the gun itself. I have stripped mine down to bare frame, trust me, don't do it!

You probably won't affect the spring storing the gun like that. But if you want, order a replacement from Beretta for about $2-3 including shipping.

To replace is easy:

-Take grips off
- Hold gun or frame from top pushing down on lanyard ring on a solid surface
- use a pentip or punch or whatever to push out pin holding the lanyard cap in
- By pushing down you are taking the spring tension off of the lanyard ring and the pin should slide right out and that's it!
the mainspring will slide off of the hammer strut and you can replace it with stock, M1911 18lb or 92D.

Took longer to write than to actually do it.
 
to minimise the distance the hammer is cocked put the cable thru the mag well and ejection port as normal and then close the slide on it. then the slide will only stay open about 1/4 of an inch or the width of the cable and this will also help the recoil spring last longer.
 
The hammer spring is effected in the same ways as a magazine spring, or basically any spring. If a spring is designed properly for its use, then even if it is fully compressed (not over compressed)then it will last just as long as if it were uncompressed. (A properly designed spring will not take a set when compressed and uncompressed through its designed length of travel.) Springs get worn from the number of cycles they go through, i.e. the number of times it gets compressed then uncompressed. That should be the factor you should be thinking about in terms of spring wear...
 
P-35- thanks. It was a little aggrevating to get it back together, but at least I know how. and I have a spare of each type of spring, so I am not going to worry.

Russel- I used to use a 1/4 inch cable and I could actually not fully cock the hammer if I did it correctly. I still close the slide on this cable, but it is about 3/4 inch thick if you include the rubber coating. I am careful to not leave stress on the extractor or slide stop. This leaves the recoil spring half compressed. I will change the recoil spring every 2 or 3K rounds.

I feel better knowing where to buy springs and how to replace them. www.gunsprings.com
