I just recently switched guns and class in IDPA. I am now running a Springfield 1911 in 9mm and have 6 of the new Wilson ETM 10 round mags,,,,,,,,,here is the kicker,,,,,,,,they function and feed great 100% of the time.....................but when dropping the slide from slidelock, they occasionally will not feed the first round(i have to tap the slide).........I started out with a 10# recoil spring ,,,,,,,,then 11#,,,,,,,,now up to a 12# for the next test (not tried yet).
My OAL is 1.116 which feeds and functions great (handloads), it is always when dropping the slide from slide lock that get me?
Any ideas would be appreciated?
Thanks,
Jerry
