I have a brand new M9 that I just took to the range yesterday. Put my first 200 rounds through it. I had one misfire and on 3 occasions the slide did not lock back after the last round. I used a combination of Remington green box and PMC bronze ammo. As I said, the gun is brand new out of the box, and I didn't clean or oil it before shooting it. Is this something I should be concerned about?
Berettas like to be run lubricated. Not a great 'dry out of the box' pistol. But keep it lubed (I use TW-25 grease) and I think you'll never have a problem again.
If I don't use it for a while (say, a few weeks), is it a good idea to just take it down and lube it once/week or so?
