Automag III 9mm Win Mag

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Ok, This is what I found on my Frame/Slides. First, everything was made in Irwindale, Ca.

I compared a Automag III Series frame 30 Carbine, Automag IV Series frame 10mmMag, Automag IV Series frame 45WinMag and Automag V Series frame 50AE. I’m only interested in the slide to frame compatibility and NOT the exact measurements(unless somebody sends me a mic). I took some pics and made notes for all too see, I forgot about the Automag V 50AE pics, sry.

Anyway, the FRAME of the Automag III Series is SMALLER than the Automag IV and V Series refer to pic #1 and #2 and see the difference, wow!

Here’s where it gets weird!
I purchased a Used 45WinMag(only one I could find at the time). I knew it came with a ported slide but the barrel was not and always wondered if the first owners had the ports done or they didn’t like the ported barrel and purchased an un-ported barrel. As I pulled my 45WinMag slide apart I notice in front of the eject port on the underside “50”. So now I think they either broke the factory 45WinMag slide and brought a replacement slide which a 50AE ported slide was sent OR the guy was an idiot and switched his 45WinMag slide with his 50AE slide while cleaning both at the same time(opps!). Anyways, that got me thinking about the Automag V Series 50AE. So I pulled that one apart(so many parts out here now!) sure enough that Slide is marked underside with “50” as well.

So the Automag Series III is NOT the same Frame as Automag IV or V
The Automag Series IV 45WinMag Frame is the same as Automag V 50AE Frame
BUT the Automag Series IV 10mmMag Frame is NOT the same as ANY other Automags Frames!
Refer to pic#3 the Slide rail on the Automag IV 10mmMag is taller! You could fit the 10mmMag SLIDE onto the Automag IV 45WinMag Frame BUT it would be loose up/down wise and I don’t think it would be safe with that much play, not even sure it would rack or fire and NO I didn’t put the slide on knowing the rail difference.

I did try to stuff a mag from the 10mmMag and the 45WinMag in the 30 and the very last ½” or so was really tight and I wasn’t going to jam it in, so no it doesn’t fit. I also notice the 30mag indents at front, prob cause of the recoil round spring inside mag(?) to be held but that could be the issue at the topside in mag well causing the square mags from the 10mm/45 not to go all in OR the mag lips are much wider and top out on the bottom of the much narrow slide. Either way the frames are different and so are the slides as noted in pic#1 and #2 so unless you build your own slide to fit it which isn’t worth the hassle(I think).

I hope this clears up the frame and cal issues, feel free to ask anymore questions while I still have them out from the safe and apart.

	Thanks for shearing those pictures XPOO1. While I'm certainly NO expert on this, and I'm just talk about the guns I have, mine are different. To start, about the .30 and the 9mm magazines. (I dont have the whole pistol in 9mm, just 1 magazine) The 9mm mag I have does fit inside the 30 pistol, but the feeding is a dissaster, actually, it jams all the time. Here are the pictures from both magazines, you'll see why they dont work. Watch the magazine follower, the feed angle of the front part is much longer on the 9mm, and the .30 follower push the cartridge higher due to the change (wide) in feedlips. Not very well visible, but the 2 mags in front to each other. 9mm in front, 30 in the back. If you put both mags flat on the 'spine' you will see a small difference in the feedlips angle, not much but it is there! Here you can see clearly the difference of the followers and wide of the feedlips.

	Here some more information about MY pistols. To start, my pistols are as follows: .30 = AMT 10 mm = IAI .45 = IAI .50 = AMT Maybe that could explain some things? The line-up: Not much difference here, except for the .30 which is of course a smaller frame. The difference between the other 3 is minimal (at first sight) except that the slide on the .50 sits almost flush with the back of the frame compared to the others. Detailed picture below About the differences between the .30 and ALL other frames, the biggest difference is that the .30 frame has NO feedramp on the FRAME, and the barrel stops (rearward movement after unlocking) to a cross pin in the frame. All IV 's and V's (10mm, 45 and 50) have a feedramp built into the frame not on the barrels! Picture tells a 1000 words: Plenty more of this information is explained in the DVD "Automag pistols"

	Now about the frames and feedramps of the IV's: My two IAI in 10mm and 45 winMag: Sliderails look identical on my two: But here the differences in wide between the feedramps 10 and the 45, note that the 10mm is smaller as the 45: One remark about the slides, just my .50 cal slide is marked 50 on the inside. (cast into the metal, not engraved) So my personal conclusion: All models have their own caliber frame/slide/barrel configuration, or quality control was a dissaster at AMT/IAI... Or, what I remember what Lee Juras once told me, all automags are prototypes...

	WOW Thanks guys I was lead to belive that the 30 frame was the same. I knew the 50 was different . I know my 9 mm mag. upper was fitted on to my .30 by the factory AMT/IAI . It's been 20 yrs since it was there or so . I remember a smith I talked to, think his name was Tony and all my Automag III magazines are the same as he recomended . I think he told me to "tune/bend" the mag lips if it gave me any grief. Thanks Luc V for the pretty pics . John

	Luc in the pic 1 , the rear sights on the .30 carbine should be searated black . My 9 mm Winmag upper has the two dots like you have in the pic .

	mohili... sorry, not pretty pics, you should have said greasy pics Just two more pics from the magazines of the 10 mm and 45 WinMag. Except for the minor distance (wide) in feedlips, they look alike. Well, to keep them appart and not haveing to measure them, I engraved my 10mm !

	Mohili... My .30 is a AMT and so is my 50. Both those guns have white dots in the sights, the 10 & 45 are IAI and are black serated. Could this explain something? What about your .30 and 9mm, both the same AMT? Thanks, Luc.

	hmm... interesting. So the AMT's have white dot Sights and the IAI's black serated? So let's gamble, the pistols from XPOO1 are: 45 winmag = AMT 10 mm = IAI .30 = AMT Am I correct XP001? The more you look at those pistols, the more questions rise...
