Hi folks. Sorry I don't post much, but I do drop by once in a while to see what's happening. I just don't usually sign in. I've had a C9 since 2006 and am picking a LNIB JHP tomorrow. They're a nice fun addition to the collection. I saw this part for a mod on that beloved auction site. I'm not sure of the offsite link rules, so you can search for it if you want to. It looks to be a threaded replacement pin for the OEM slide retainer pin. Cost is $6 with free s/h. The supplier claims that one can switch back to the stock pin anytime. However, if this mod cuts a thread into the polymer frame, which it certainly would have to in order to seat, couldn't this cause a reinstalled stock pin to have less tension than spec. Has anyone had any experience with this mod? If so, have you reinstalled the stock pin since and noticed any creep?
