Folks, check your springs on (Mecgar) factory mags.
I've had increased fail to lock back on last round. Had my smith check it out yesterday. He said "mags" - I'd spent much time trying to figure it out and I didn't want to believe that. He grabbed a new (blue) Mecgar, stuffed it in and it caught every time. I bought it.
At home, I took the new spring out and stuffed it in the factory mag case - caught every time - did the other one - caught every time.
THEN - while they were all laying there on the towel I looked - and, lo and behold, the new spring was longer. Old springs collapsing? NO!! Maybe, but...
Counting the loops at one end of the old springs I counted nine, the new spring has twelve.
So count your (full) loops.
Now I wonder how many loops seven round mag springs have? Or did they just weaken and collapse. My factory mag springs now just barely top the floorplate on insertion - they were longer when new in June.
I guess that speaks to having more mags and rotating them often - I had just the two and kept them full since June - and only 300 rounds fired.
New springs will make'em work.
