P9 Mag Release Issue

[iWander]

I just bought a like new P9 for a screaming deal. It'll be my son's Christmas gift as his first handgun and his CCW.

I detailed stripped it, cleaned and lubed it and then function checked the gun and all 3 magazines. The two 7 rounders work perfectly and eject well. The 8 rounder ejects better than the two 7rd ones, but I have to slam it really hard to get it to seat. I've checked the dimensions of all three mag bodies all the way around and they're identical. The extended 8 round magazine pad does not hinder the magazine from seating. It's almost as if the mag release cut out is lower but it's not. Any ideas?

Strange, one would think it would be the other way around. The release is obviously catching and releasing properly on the 7's. The 8 rounder has to have the notch slightly too low. It does the same thing with the slide locked back?

I don’t have any ideas but that pistol sure looks good.

Thank you gentlemen and great idea Colonel. I tried it with the slide back and there's zero difference with it locking. However, since there's no slide tension I was able to freely move the magazine in-and-out. I think the problem is the extended base pad is too tall. I'm gonna try gently sanding a little bit off the top and see if that makes a difference.

I discounted that issue as you mentioned in your post that the extended mag base pad did not hinder the mag from seating.
I'm sure you'll find with a little judicious material removal from the top you'll have a happy ending. Fingers crossed.
