Has anyone had difficulties with light primer strikes with an R-9 and Fiocchi 115g ammo? I've never had a problem before with the R-9 and any other type ammo. Also, what is the procedure to remove the firing pin/spring for cleaning, or must that be done at the factory?
Thanks,
Ron
I had no difficulty with Fiocchi 115g ammo last week.
However, all of the cases I recovered (Fiocchi + three other brands), SEEMED TO have relatively shallow primer strikes. (So did the two fired cases that came with my new R9s. These were Federal cartridges, which are supposed to have the softest primers.)
I say "SEEMED TO," because when I used a magnifier to compare the R9s shells with casings ejected by other 9mm pistols, the strike depths looked similar (I don't have a gauge to measure them), but the R9's strike circle looked considerably smaller.
Has anyone on the Forum done a true comparison?
I peeked at the tip of the R9's firing pin (by pushing the back forward against the return spring). It appears to have a smaller diameter than the pins of my other automatics, but a comparable length. The return spring tension also felt comparable to other pistols.
If this unscientific analysis is true -- the "light primer strikes" may actually be "narrow primer strikes." Some brands of ammo may require a more energetic strike.
I wouldn't attempt to remove the firing pin, but it's easy to check for dirt and crud at the front and rear. Many (most) manufactures recommend against oiling the firing pin, on the theory that the oil can attract gunk and prevent easy movement.
