Was at the range yesterday and first off I wanted to shoot a box of my latest SD ammo for testing (Hornady TAP 147gr) Worked great except for one thing... In my 7rnd mags of which I have two, the slide failed to lock back after the last round. This was not an issue with my 6rnd mag. And also was not an issue with any of the mags using my 115gr practice ammo. My thought is that the mag was not quick enough (or strong enough) at locking due to the increased recoil of the 147gr rounds. Anyone agree? I have just ordered two replacement mag springs from Wolff (5% XP) and hope this cures it. I have another box of Hornady TAP to test again. I also have a box of Winchester SXT 147gr to see if it's the brand of ammo.
Hmmm... Wonder if I shouldn't just get Wolff springs for the six rounders too?
FYI... The gun is broken in at +350rnds
Any thoughts? Anybody else have this issue?
