Well, I put Wolff +5% 9mm/.40 mag springs in 3 of my 6 7-round .45 mags. They are 18 coils and seem to be the same size coils... a PITA to install, especially after the first when I remembered to lightly oil the springs. That sure helped install them a lot... NOT! I did cuss a bit.
I'm going to the range to try my new P45 again after threadlocking the SL screw a few weeks ago.
I hope I get the results that I want today.
