Took my new Mark lV 22/45 to the range for the first time yesterday after an initial cleaning when I brought it home. Using Aguila Super Extra 40 grain ammo. First mag almost all were light primer strikes and failure to fire. Second mag got a little better but still several ftf rounds per magazine. This was consistent for approx 100 rounds. Then switched to CCI Mini Mag 40 grain and it was better but still at least one ftf per mag and this continued for another 100 rounds. I have owned several Mark pistols back in the day and never had a problem like this. This is the first one I have bought in many yrs and now should I send it back to Ruger or is there a simple fix I am missing?
