Seriously... when the sights begin to go, its time to get rid of the gun. It's a Glock anyways... so no one here will really want it. Except me. You should send the entire gun to ME. Free of charge. Because I like you, I"ll even pay the shipping charges.
Trust me... I know what to do with it, While it may take some getting used to.... I will take it upon myself to see that your Glock is cared for in its old age. I promise, there will be no charge to you for me to take this aging relic off your hands.
With the extra room in your safe, you could purchase a new HiPoint 40 caliber.... or for just a few hundred more, you could get a new Springer XDm.
Just willing to help another Cotepian where ever I can. If you can stop laughing long enough to respond.... Just send me a private Message and I'll provide the address to mail your Glock to.
