Hello, and thanks for using Just Answer! My name is ***** ***** I am happy to help you today. I'm reviewing your question and will reply back momentarily.
Do you happen to know who made the kit?
Ok...did it convert to a .22 or did it stay as a 9mm?
ok...let me see if i can do some research and find it.
I'll do my best....
I have not been able to find the kit you saw. I am going to opt out to see if someone else may have better luck.
What you are thinking of is the Hi-Power Detective Kit. The slide and barrel were 1" shorter than the standard 4 7/8". Sportsmans Guide had limited quantities and sold out pretty quick.
A kit sold recently on E-Bay for $475. I was not able to locate any current listings on E-Bay, GunBroker.com or GunAuction.com.
Keep checking the auction sites and E-Bay or try listing it on one of their "wish lists" The cost could be as much or more than buying a compact 9mm made by another company.
The following link is to the old Sportsmans Guide listing.
