Kart 22, Colt ace firing pins

Do Kart 22 and Colt ace use the same firing pins.
Have a mixed bag of parts trying to figure which is which.

The first one on the left (#1) and and numbers 3-7 look like the one in my Colt Ace conversion.

Yes the Colt Ace and Kart and Dworak use the same firing pin. There is a difference in some of the pins. The early ones had a square shoulder where it reduced to the smallest diameter. Later ones rounded the shoulder to prevent breakage.
