Found the slide pin modification in a kit for sale on EBay. I looked and did not find anything and e-mailed the seller (innercitydetroit). He quickly responded that he listed some more on the site. I used Buy Now and go the kit with two slide pins, tap, and an allen wrench which were altogether $18 and $3 shipping for a total of $21. I know some smart folks out there may have researched this before and came up with their own ingenious way to modify their gun as opposed to using the old hammer and punch method. Just thought I'd share. No I don't have anything to do with the sale, purchase, or profit of these items. Just wanted to let those that may be curious know that the kit is out there if you look.
