Product Review: Mag Guts +1 Magazine Springs And SSA MagFix Baseplates

I’ve pretty much settled on the Smith&Wesson Shield in 9mm as my “go-to” carry gun for more-casual occasions.

I can hear the teeth gnashing as I type this, but the fact is, I’ve trained with this gun, I know what it is capable of, and I am absolutely confident in my ability to perform with it on-demand. However, with 8+1 rounds it’s not the highest capacity gun on the market right now, and it means that carrying a spare magazine is usually a good idea.

Enter the MagGuts +1 Follower. At $22.95, it costs around what eight round Shield mags are going for these days, but it works as advertised. I popped the baseplate off of a S&W 9mm +1 mag, dropped out the existing spring and follower, and slid the new base plate right back on. I did have to do some spring-wrangling to get the follower to line up, and unlike the stock spring, the edges on the MagGuts spring are sharp and pointy. No blood was shed in the alteration of the magazine interior, but I did get the point, and I got it often.

I also received a couple of MagFix baseplates for the 8 round Shield magazine, and these are terrific. I had been using pre-production aluminum MagFixs on my Shield mags, and I was curious to see how the plastic ones would compare. The good news is, they’re easy to install and work well with the MagGuts +1 follower. The only change I had to make was to use the standard S&W baseplate instead of the thinner MagGuts plate, but it was an easy fix to make.

The MagFix is a great addition to the Shield: Besides solving the sliding insert problem, there’s a little lip on the bottom of the sucker that adds stability to my firing grip and makes the gun feel more secure in my hand. Also, it’s a low-profile solution to the 8 round mag baseplate issue. Other magazine baseplates for this gun, like the ones from ProMag or Taran Tactical, add bulk to the butt of your gun, making them harder to conceal. The MagFix, though, is essentially the same size as the S&W magazine and prints much less than other options.

All of this is moot, however, if the combination doesn’t work, so I shot 50 rounds through the MagGuts / MagFix combo over the weekend, and there were no issues to report. I would have liked to do more, and I will, but my initial impression is that this is a great way to get one more round out of your Smith and Wesson Shield, and if Nigel Tufnel taught us anything, it’s that one more is ALWAYS better.

The bottom line is, if you have a 9mm Shield, these would definitely be two additions I’d add to your gun to make it a more effective fighting tool
