Was curious to see if anyone has replaced just the spring on a spring loaded slide mounted decocker for the 4506/4566 or 4006tsw CHP? Kinda thinking the whole barrel assembly replacement is needed at this age point of our pistols since parts are getting scarce. I have 3 new springs I thought would work but they're for the frame mounted decockers. I wanted some spares just in case the originals broke. If I can't find any I'll just limit the use. Thanks!
