Wanted: glock17 gen 3 22lr conversion kit

I bought an advantage arms glock17 gen 3 22lr conversion kit and it doesn’t fit me Glock17 Gen 3 RTF

I have two 9 mm slides for my Glock and they both fit perfectly 

Does anyone have a clue what could be wrong?  

I am not willing to mail my Glock and the conversion kit to the shop in BC who sold me the kit (High Caliber)

Help appreciated ! write me if you have ideas
