I will never understand that logic.
Here's a darn good pistol, accurate (for me, anyway), reliable, hard-hitting, light, great concealment.... yeah, making it better makes no sense.... How much will a lifetime of ammo cost? Do people limit themselves to $200 of ammo on a $200 gun?
But having ranted all that, I'm not sure if anyone does make them. I'd start with Lakeline. Or eBay.
