The 9mm Wilson ACP that I recently reviewed for the M1911.ORG E-zine came with two of the new design ETM magazines. They were noticeably easier to both load, and seat into the pistol with the slide forward, than any other 10 round 9mm mags I’ve ever used, including Wilson’s previous generation of ETM magazines.

I have a Wilson Professional Model (four inch frame and slide) that I’ve had for over 10 years now, which was made back in ‘06. I bought it to shoot IDPA ESP class with, and was never interested in carrying it because of the ambi safety it came with. I would have changed it out immediately, but the frame and all small parts except the hammer are finished in OD green Armor Tuff.

I recently (better late than never, I suppose) decided to update the pistol a bit. I replaced the ambi thumb safety with a single sided one, and added a one piece mag well, both from Wilson, and in OD green. I also got a new pair of stocks to mate up with the mag well.

Now, this is where the new magazines come in. After installing the new parts, I decided that, since the ambi was now a thing of the past, I’d put the pistol into my carry rotation. Remember, I had 10 years of history shooting it, with no functional issues to speak of. Well, just imagine my chagrin when I couldn’t get a full magazine of hollow point ammunition through the gun without failures to feed! Since it was a range gun, I had never tried to shoot it with any hollow point ammo. That was when I remembered how nice and smoothly the new design mags that came with the ACP 1911 functioned. So, i ordered four of them from Wilson, and loaded a couple with hollow point ammunition. I was able to hand cycle all 20 rounds from both mags through the pistol without issue. Things were definitely looking up! So, I took all four mags, along with the Professional Model, some 115 gr FMJ, and two different kinds of hollow point ammo, to the range yesterday. Everything ran through that pistol like grease through a goose! Of course, the ball ammo fed without any problems. I then shot the Federal 115 gr JHP, which has a rounded bullet profile, and Hornady 115 gr JHP, which has more of a truncated cone (TC) bullet profile. TC bullets seem to be more problematic in feeding in some pistols. Both fed flawlessly for me now, using the new magazines.

So, if anyone with a 9mm 1911 has been experiencing feeding issues; I recommend that you give these new Wilson ETM magazines a try. They certainly provided a drastic improvement in feeding for me!

The 9mm 1911 magazines that I’d previously used were the original Wilson 10 round ETM mags (10 years old now), plus several nine round mags from various manufacturers.

Thanks Rick, I need to find Defense ammo that is near max spec length for it to run in my Pm9. It is definitely persnickety with defensive loads. I’ll definitely give these a try,

Rick I’m curious about something.
Maybe you or someone else here knows. How does one tell the difference between the old and new ETM 9mm mags?
Different follower?
Different looking tube?
What?

may like to get some and of course would want to make sure I get the ‘GenII’ ones I guess is what they would be?

Order direct from Wilson and you'll get the new ones.
Prices on the newer style mags aren't much different ordering direct vs a supplier.

The old ones are a bear to unload.
How are the new ones to unload.

Yeah about the same I would think.
I keep two with full springs for carry
The rest I cut 11/2 coils off and use for USPSA shooting so I can unload them.
Then change springs once a year so I don't get any FTF out of a weak spring.

Are these the “Next Generation” ETM 9mm magazines introduced around 2015 or is there a third generation of this magazine?

Old gen ETM's are not numbered on the side, new ones are numbered. Also, there is a dent at the top of the front side of the tube on new gen ETM's. Vickers have the crease but a solid tube.

I have had good results with the CMC Range Pro 9mm 10 rounder as well.

Both styles are hard to unload. Have found Tripp's to be the easiest to unload.

They’re the third ones from the left in Moad’s pic.

They have stainless steel followers, a different mag tube shape in the front, and (I checked since you asked yesterday, Saiid); they don’t have a flat mag spring. They also hold and feed the cartridges at a higher angle than my old ETMs, which have composite followers.

The mag shape on the front of the mag body (tube) is important, as that provides support to fhe cartridge (similar to a feed ramp) as it’s being pushed forward by the slide, which helps to prevent the cartridge nosediving, and striking the feed ramp too low.

That’s because of the propensity that 9mm 1911 mags have for the cartridge to nosedive, and impact the feed ramp too low for HP ammo to feed reliably.

They’ll make a big difference, Jeff.

That’s right. Every site I checked prior to ordering my mags from Wilson, based on their pictures, were selling the composite follower mags (old style).

That’s why I ordered mine from Wilson.

Rick is exactly correct.......and I hope I did not create confusion with my fourth (4th) picture from the left. I checked my box of mag parts this morning and sure enough, found the empty packaging for a spring/follower kit (500SFK9-10). Apparently at some point in the past, I changed the original polymer follower for a metal one. I have never had issues with this original magazine, but as pointed out, it is missing the front dent/ramp.

Sorry if this confused anyone.....just trying to help out.
