40c magazine problems

[kenner]

My new S&W M&P compact 2.0 in 40 S&W has magazine problems.
My -2- factory S&W 13 round mags. will not drop free, they come out approx. 40% and stick. When the mags. are loaded it is worse.
Any one else have this problem?

I have this problem when the magazines get dirty. What I do is thoroughly clean the magazine well and the exterior of the magazines. Then I place a drop of oil on a cleaning patch and rub it lightly over the magazine exteriors. Then I buff off the oil with a paper towel or a rag. They always drop more easily after that.

OK, I have fixed the problem.
There was a small casting ridge in the plastic approx. half way up inside the mag. well. I took a small flat file and filed the ridge all the way around inside the mag. well and now the mags. fly out of pistol.
Took about 6 minutes.
