Also make sure you function check your fully loaded gun. Sometimes these can put too much pressure on the mechanics and the next round won’t load properly. I’ve heard of guys who just load one less round.

Tex1961,

Thanks for the info. I'll load it with 13 and let it sit for a few weeks and then check it out. Wouldn't like to load one less round as the extra capacity is one of the reasons I bought it (day before yesterday!), but, if that's what it takes, I'll do it.

I sent 4 mags in along (at my cost) with a copy of the email. in about 2 weeks I got 4 mags back. I don't know if they are the same mags with new internals or new mags. They are stiff to get 13 rds in but they do go in. They have gotten easier after leaving them loaded with 13.

I've heard 2 theories about what is causing the problem:

1. The follower is incorrect in early production mags and has since been corrected.

2. The spring is too long and needs a coil cut off.

Good luck.

I just bought the gun day before yesterday, so I assume it's the latest production. And I would hate to cut a coil off the spring because I'm afraid it might foul things up. Think I'll just load it up with 13 rounds and leave it sit a few weeks and see what happens.

Thanks for the reply,

Anybody else having trouble loading the 13th round into the 9mm Shield Plus 13-round mag? Not only is it hard to get that last round in, it's also really hard to insert the mag into the grip and ejecting the fully loaded 13-round mag is difficult as well.

I've read that S&W tech support says load the mag with 13 rounds, then let it sit for a couple of weeks and it will be easier to do after that. Anybody know if that's correct?

Thanks for any input,

Crash

P.S. Really like the gun--feels good in the hand and feeds, fires, ands ejects all kinds of FMJ and JHP with no problem.
