Got her back Monday, shot it on Tuesday.
Things went much better...not perfect...but much better.
Out of 60rds of Remington 230gr FMJ, I had only 4 FTF....and I did notice a slight pattern.
Two of the FTFs were with 8rd mags...the very last round in each mag. The other two FTFs were with 10rd mags...one was last round in mag and other was the next to last round in the mag.
Some of my 8 rounds mags are older, and the 10rd magazines are older. Ruger specs also say this platform is intended for 7rd mags.
So, for the last few rounds I transferred rounds from an 8rd mag to the Ruger 7rd magazine. No issues.
Ruger did perform a repair on the extractor, and now I suspect that this gun may have a preference for 7rd magazines, and some of the magazines I used are older.
I have ordered 4 new Tripp magazines, two 7rd and two 8rd. I'm going to see how they work in it.
