2nd time to yonkers for slide not holding back, still will not hold back after last shot. yonkers did almost fix the fail to chamber problem.
last week, after 2nd time, shot 150 of 5 brands, very very few fail to chamber or stovepipe, but many many refusals of slide to hold back after last shot.
yonkers said after the 2nd return they fired 4 magazines and had no
problem with any of my solo's functioning.
this am shot 75 hornaday, 135gr critical duty, for an experiment, 3 numbered magazines that they exchanged with my 3 factory magazines.
i shot single shot to determine if slide would hold back:
#1 slide never held back,
#2 slide held back almost every time,
#3 slide had more refusals to hold back than #2.
also shot6, 3round, mags, same results as above.
bottom line: i got 2 factory
magazine that do not work well. guess i'll call yonkers and see about an exchange.
solo is getting there, it is almost reliable.
that the 2 magazines were defective by pushing up on the base of the magazines with my other thumb, while firing single shot, every time the slide locked back. the magazine catch slots are out of specs. called Kimber and they are sending me 2 new magazines. maybe final problem solved, whew!
6/27/17, took 2 8 round kimber magazines that they sent me to range, shot ~80 rounds, they worked without fail.
so now i have 1 6 round and 2 8 round mags.
