Here is a bit of a puzzler for me.
My daughter shot a S&W Model 10-6 and a Ruger P89 9mm.
The Smith is a used police trade-in I got a couple of months ago. I test fired it with 50 rounds and it functioned fine with no misfires. However the cylinder was very difficult to open which I traced to the end of the center pin having a dimple in the center of it. To correct this I slightly shortened the end of the ejector rod and center pin until the dimple was gone and the gun unlatched easily. Using ammo for the same batch of my reloads with Winchester Small Pistol primers she had two failures to fire. Both primers showed light firing pin strikes.
With the P89 using my reloads with WSP primers she had one misfire twice on the same round with light hammer strike. It fired just fine for me (3rd strike). She had no failures to feed or eject.
Can too loose of a grip cause misfires?
I have reloaded for many years and am very confident that it was not caused by me failing to seat the primers fully (high primers). See my comment about the revolver test firing fine. Also note both guns and ammo work 100% for me.
My daughter had not shot a handgun for many years and needed a lot coaching on proper stance (I had her use a Weaver stance), grip, trigger pull and sight alignment. Could she have been relaxing her grip just enough to allow the guns to misfire? Revolvers are forgiving about improper grip. However I am stronger and use a firmer grip.
Ok to discount mechanical I am going to replace the center pin and ejector rod on the revolver even though it does not have excessive endshake. On the Ruger I am going to replace the firing pin spring. (Parts are on order).
