I can't even remember how a 31 is different is that the 40 version? I know the alloy frame version is like a 30PK. I never understood why Promag even tooled up to make magazines for an obscure gun with probably not too much importation. Guy I gave the 30M to many years ago grinded on the Promags and got it to half azz work.
I didn't even realize Triple K made mags for these but they make mags for about everything. Remember if you come across any Promags for it they suck as well. Unfortunately it has a 0% success rate in actual feeding of rounds into the pistol.įactory Mag on left, aftermarket on right. The magazine in this picture inserts, seats, and ejects fine. The aftermarket mag is a bit blockier and has a plastic follower.
The factory has a metal follower and a more round profile. This is a comparison of the factory versus aftermarket mag. I took some additional pictures as I was troubleshooting the problem further. It takes holding the magazine release button and pushing down on magazine from the top (slide open) to get it out. This creates a secondary problem in that the magazine is now being bound in place by the trigger bar and will not drop free. The non-functioning magazine(s) will lock in, but create drag on the trigger bar, gumming up the action. The trigger bar moves freely toward it as the trigger is squeezed and completes its movement and returns to reset without contacting the magazine. The functioning factory magazine goes in fine, clicks in, all good. That is sort of the problem, but not exactly. In this case the trigger bar or mag disco is acting as a gauge and not permitting the other mags to go in easy. Perhaps the wear spot on the side is where the others are binding?īottom Magazine is good, other two are not. But these guns and magazines are out of production and the factory magazines cost literally $75 - $100 each. If this were a Glock or Beretta, I'd get rid of the non functional magazines and replace them. I am more interested in getting everything into working order than I am in trying to return anything. That is certainly a possibility, but if they were just too tight I don't see how it would be affecting the trigger pull.
The magazine disconnect in the pistol is intact and the pistol does not appear to be altered from the factory condition whatsoever.Īny suggestions are welcome! It has been suggested to mic the spare magazines and compress them to spec if they are too big. I am completely in the dark here, although I do not think the issue is the magazines. All have the same metal follower and none appear to be damaged or altered. I placed all 4 magazines side by side and all of them are dimensionally identical. It had the same negative results as the other magazines, binding the action, inoperable, and very difficult to remove. I also sourced a third factory Star magazine from a different source so I tried that one. They do not function whatsoever with this pistol. Again, a great deal of force was needed to pull it out.Īt this point, I was of the opinion that the magazines I got were perhaps out of spec or some other type of incompatibility. The second extra magazine was inserted and again binded up the trigger and rendered the gun inoperable. I reinserted the original magazine and it worked fine, so the gun was not hurt. I was finally able to pull it out with great effort. But it binded the trigger and rendered the pistol unusable. When I inserted one of the extra magazines, it went in flush and seated. I also purchased 3 additional used factory magazines, which were quite pricey. The pistol itself is like new, with virtually no wear and in pristine condition.
It came with one (presumably) factory 15 round magazine that functions fine. Opinions are needed on some unexpected issues. Relatively uncommon but popular among owners. It is one of the earlier "wondernines" and is a heavy, all steel beast. I recently posted about the acquisition of a Star 30M 9mm pistol.
