I love my Cx4 Storm carbine, as I have mentioned and reviewed. Particularly once it was set-up to deal with the additional power of the .45 Super cartridge, it has proven to be a reliable and formidable home defense gun.
But there is ONE thing I don’t like about my Cx4: in .45 ACP/Super, the magazines only hold 8 rounds. Beretta doesn’t offer a larger capacity magazine.
Wait — let’s make that TWO things I don’t like about my Cx4: the standard magazine fits up inside the mag well, such that it can be hard to extract and may pinch your hand if you try to do a quick change of mags.
Wait again, there’s a THIRD thing: while there’s ample room for it in the composite buttstock, Beretta didn’t see fit to include storage for one or more additional magazines.
OK, so here are some solutions I came up with to deal with these problems.
The first two problems are fixed by an after-market product which extends the standard mag by two rounds, and is designed such that it fits with the bottom of the mag well and won’t pinch your hand during a fast magazine change: Taylor Freelance Extended Magazine Base Pad. They’re not cheap, but they’re well made and work fine.
To deal with the storage problem, I picked up an inexpensive 4 pistol mag storage pouch, intended to go on a belt or MOLLE system. With three simple snap-on extensions, I was able to fit it so that it held snug to the butt of my carbine, as shown:
Here’s the back, showing the snap extensions:
And lastly, I positioned the pouch ‘upside down’, so that when the velcro tab is pulled, the mag slips out, positioned ready to insert into the carbine. As you can see:
Since I am right-handed, the mag pouch doesn’t get in my way, and it puts an extra 40 rounds immediately available such that I don’t even need to take the carbine down from my shoulder in order to quickly reload.
It’s not perfect, but it’s a good workable solution to the limitations of the Cx4. And now I love my little carbine even more.
Yesterday I took advantage of the unseasonable warmth to get out to the range and have a bit of fun & practice:
Yeah, those cans jump pretty good when popped with .45 Super rounds, particularly out of my Cx4 Storm.
Which, this time out, was a lot more fun to shoot than when I last took it out. Because I had gotten around to adding a slip-on recoil pad to it. Specifically, one of these: Pachmayr Decelerator® Slip-On Recoil Pads (Not a paid ad, and I got mine from a different seller.)
Because while you want to take steps to manage the power of a round like the .45 Super on the INSIDE of your firearm, you also have to take steps to manage the recoil you experience on your body. Or you’ll avoid practicing. Or will develop bad habits (flinching, grimacing & closing your eyes, etc). Or you’ll be spending money on painkillers, bruise ointments, and massages that you can more profitably spend on ammo/components.
While I like the overall design and ergonomics of the Cx4, the thin rubber ‘recoil pad’ it comes with doesn’t actually do much to tame the recoil, particularly out of .45 Super rounds. So I spent some time looking over different products to help with that, and settled on the Decelerator. Here’s how it looks on my gun:
I was really pleased with the difference it made. Easily knocked off at least half of the felt recoil. Probably more like 3/4ths. And the added lengthening of the stock isn’t at all a problem for me with my long arms.
And of course, if one of my friends wants to prove how macho/masochistic they are, it’ll slip right off … 😉
However you do it, take into consideration how best to manage recoil in your firearms. I’m not recoil-shy. Never have been. But it just makes sense to be kind to your body over the long haul.
PS: the optic is a Vortex Venom holographic red dot sight. So far, I really like it.
Today we’re going to look at the results out of a stock Beretta Cx4 Storm in (obviously) .45 ACP. I have previously reviewed the Cx4 Storm in .45 ACP for Guns.com, and it is a great little pistol caliber carbine with a 16.6″ barrel. Here is Keith shooting the one we used for this recent testing:
I want to re-iterate that the Cx4 was completely stock, with no modifications or additions whatsoever for these tests.
As I said with the previous posts about these tests, it’ll be a while before we have all the data crunched and the website updated, but I thought I would share some preliminary thoughts and information through a series of informal posts.
Quick note about the data below: All the ammo used, with the exception of the four * items, were part of our overall test sequence and had three shots made over the Oehler chronograph (which is a double-unit, and automatically records and then averages the two readings), representing a total of 6 data points. I’m just giving the overall averages here; the full data will be available on the website later. The four * ammunition types only include two shots/four data points through the Cx4. That’s because we only had one box of each of this ammo, and were wanting to get data which would be of the greatest use to the largest number of people.

Something in particular I want to note: that in comparison to .45 ACP loads (whether standard pressure or +P), a number of the .45 Super/.450 SMC loads gain significantly more from the longer barrel. Compare these numbers to the previous posts of handguns, and you can see what I mean. You typically only gain about 10 – 15% in terms of velocity from the .45 ACP loads in going to a carbine — and this is very much in keeping with our previous testing of that cartridge. But you see upwards of a 30% gain in velocity out of some of the .45 Super/.450 SMC loads … and that translates to a 50% increase in muzzle energy!
A heavy, large projectile hitting with 900 – 1,000 foot-pounds of energy is nothing to sneeze at. Particularly when it comes with very little felt recoil out of this little carbine. That means you can get quick and accurate follow-up shots, which is always an advantage when hunting or using a gun for self/home defense.
As noted previously, we noticed no unusual wear on the Cx4 Storm, though a steady diet of such ammo could increase wear on the gun over time. And the Beretta didn’t have any problems whatsoever feeding, shooting, or ejecting any of the rounds. Where we had experienced some problems with the same ammo out of some of the handguns, there wasn’t a hiccup with the Cx4 Storm.
Look for more results, images, and thoughts in the days to come.
Another quick post about getting together for a bit of shooting weekend before last. This time, let’s look at some semi-auto carbines.
The first two are a pair of Beretta CX4 Storms, one in 9mm and the other in .45ACP. You can see them here with the pump guns:
I’ve previously reviewed the Cx4, and would only add that each time I shoot one of these guns I just enjoy the hell out of them. At just under 30″ overall length and weighing 5.75 pounds, they’re light, easily maneuverable, and very ergonomic. Great little pistol caliber carbines.
Now, see that gun partially visible off to the right in the pic above? And here’s another shot of it with the other pumps and carbines:
See that short little thing third from the left? Yeah, it’s an AGM-1 carbine in 9mm. Here’s a much better pic of it:
It’s an old-school bullpup, made in the 1980s in Italy. None of us had seen one before, and since it was a used gun it came with no paperwork or information. In picking it up, it felt almost too small to be civilian-legal (I mean non-NFA regulated), but the overall length is a tad over 26″ and the barrel is barely 16 and 1/8th inch. It has a little more heft than the Cx4, and most of the parts are heavy stamped steel. It uses Browning Hi-Power magazines. Interestingly, it was intended to be a modular design you could easily convert over to either .22lr or .45ACP, though I doubt the parts to do so are very common now.
But it was a surprisingly nice little gun to shoot. And when I say little, I mean it — damned thing is shorter than my arm. It was accurate, had a nice trigger, and almost no recoil. All of us were able to put a magazine full of bullets into a one-inch hole at 11 yards the first time we picked it up and tried it. Cool gun. If you ever happen to stumble across one in a shop, don’t be afraid to give it a try.
