M&P9 10-round Mag Problem

Recommended Posts

I recently bought a factory 10-round full size M&P9 magazine for my M&P9 2.0 but loading the 10th round is a huge struggle.  Anything I can do to modify it to make adding the 10th round easier?

 

I realize the manufactures want to be sure you cant load more than 10 but 10 should be easier.   Suggestions?

I have taken the followers and carefully (with a flat file) taken off about 1/16" from the bottom feet, smoothed the edges and can load 10 easily. The exact amount may vary, test and fit your first one then measure for others. I overdid my first one and could squeeze 11 with effort (became my Barney mag + 10)

File down the bottom of the follower

Take your mags apart and check the springs. I don’t know if they changed the design since I bought mine, but mine were 17 round mag springs in the shortened 10 round mag body with the super long basepad. I cut 2-3 coils off the springs. Mag loading got much easier, they could actually be seated in the gun, and there’s still plenty of spring tension.

My experience has been a bit of both as mentioned in above posts. First I judiciously removed coils and then removed enough of the follower lower portions that would still allow spring contact. I even leveled off the center "knob" to make it even with the "legs".

Thanks for the suggestions.  I've filed off the follower's legs until the semi-circular arcs are nearly gone but the mag is still very tight for 10 rounds,.  I may try to shorten the center knob also.  I was wondering about shortening the spring since is seems to be just about coil bound with 10 rounds.  That may be next.

I wouldn’t mess with the springs. If you’ve filed that much off the legs maybe the block in the 2.0 mags is longer. All mine were 1.0 mags.

I haven't cut the springs so far. Also, I don't think there are 1.0 and 2.0 magazines, I believe they are all identical but maybe there are older and newer production.

 

Anyway, I called S&W's customer service and told the rep my problem.  He's sending me a new spring and follower so we'll see if that helps. Also it lets me really experiment with my old ones.

I kept my mags which had the new followers loaded in my safe with snap caps for 6 months but nope did nothing to make loading easier lol

 

Passed them along to a mate and ended up sourcing some secondhand original mags.
