Ditto Pyro.......Feature must be out of service.
Now about your Glock 19 :
I've been carrying one since '96, It was a used Gen 2(Police Trade-in) when I got it........It's still bone stock except for being on it's second set of night sights......It will feed any ammo I give it and has never failed to fire - Even though I've tortured it on occasion by running 3-4 full mags thru it non stop rapid fire till it was smoking hot.....Newer handguns have hit the market since Glock came out - But I'm still carrying my raggedy stock G19....So I suggest you shoot and carry the pistol awhile before you worry about accessories and springs(Not a fan of extended anything on a carry pistol).
The only Accessory I would mention is a set of Night Sights if it already doesn't have them, Mine came with Trijicons which are alot easier to have replaced when they wear out, As opposed to Meprolight based in Israel that uses Kimber as a distributor(I Don't even know if they do replacements or warranty work???).....And Stick with Green - They last longer.
Springs.......You 'Can' change the springs, A heavier spring may reduce felt recoil of hotter rounds, While a lighter spring my function better with really light plinking rounds - But why replace the stock spring that came with your pistol if it shoots fine ???.......And stay away from guide rods and gimmicks !!!
I say your Glock was designed as a defensive firearm right out of the box......So if it shoots fine don't mess with it.
My .02 cents....Max out.
