Well, my pup didn't do as well as I hoped today.
Two malfunctions in 75 rounds. One was a FTE where the next round tried to feed on top of the empty case still in the chamber. Ammo was Winchester White Box 115gr. Next was a failure to return to battery with a Golden Saber 124 gr. This one was also very difficult to clear. The slide wouldn't close, and the slide was very difficult to open and clear the round.
These malfunctions were especially troubling because of the difficulty in clearing them.
I'm hoping these were ammo or break-in related problems. Both jams happened in the first 50 rounds, and the pistol seemed to loosen up quite a bit during this session. I had no more malfunctions with either ammo. So, I'll be giving it another chance soon.
I can't seem to find any non+p 115 gr hollow points anywhere around here. All I could find were the 124 gr. Golden Sabers. This R9 still has a while to go before it can be trusted for carry. Hopefully I can test it again very soon and find some ammo that it likes.
