Mossberg 22 Cal. Firing Pins – models 342-740

Please see our online catalog for list of Mossberg 22 Cal. Firing Pins for the 342-740 models.

(NOTE: this page will soon show the same parts listing as the catalog page)

There is confusion in the factory parts catalog as to part numbers & illustrations for #1193 & 1465, these appear to be mixed up on various models.  But if you compare the guns that use a longer action & do take the 1465, it is clear the factory is wrong saying it is 1193.  I have factory original packaging  with 1193’s in it, so I am confident that my information is right.  I have also discussed this with other old time factory warranty gunsmiths & we all agree.  We however can not without examining many models, be sure of exactly which guns the 1465 fits.  We do know the factory parts catalog is wrong & since the factory has discontinued the guns, they do not care.

Also I have factory information inserts from parts packages that state “The #1193 and #1465 have been redesigned to prevent breakage. The new pin will fit older bolts”. This refers to the heavier tip section, & you will note the top of the bolt is slit all the way to the top, so that it will indeed accept the new style.  I believe this is why they never assigned a new number to the #1193 & 1465, but just sent the new style when the older versions dried up. I have one parts distributor who insists on the older pins, I guess he does not want the hassle of convincing his customers that the new style are better & will fit.
