So second day at the range with the Special Forces R9. Maria had recommended th t I replace the recoil spring even though my gun was reported to have had only 5 rounds fired through it when I purchased it. The replacement spring was indeed 3/8" longer than the existing spring and it also felt slightly stiffer, but otherwise apparently identical.
The first mag of Hydrashocks, no problem. The second mag of Hydroshocks, failure to feed with the first round after manually racking the slide. Couldn't get this first round to feed even with different Hydroshock cartridges. Same problem using the other magazine. THen shot one mag of WWB fine. Shot one mag with first round WWB, rest of mag Hydrashocks no problem.
So now I have fired only 3 mags and things start getting uglier. I continued with my combo of first round WWB, rest of mag Hshocks. I would get about 3 failure to feeds per mag, though these could all be remedied by pushing on the slide. I shot about 5 mags like this with FTF's at random times, sometimes the WWB and sometimes the Hshocks. On the next mag, last round I had a FTE and called it quits as I fugrued I was over 50 rounds.
I allowed the gun to cool between mags, started with a well oiled and clean gun, shot with two hands with solid grip( no limp wristing). Sounds to me like I still have a problem gun. I'll have to see what Maria recommends next.
To my eye, it looks as if the first round is lined up properly towards the ramp, but when I release the slide the round ends up moving parallel to the barrel and jamming below the ramp rather than moving up the ramp. Magazine spring problem?
