Oh, I thought you meant you had figured out the mods for the Kimber mags. Shucks! I really like the size and shape of the Kimber 7rd. It fits my hand just right and conceals better than any handgun I've ever tried.

I do use a Kimber 7-round in the Micro .380, but I put 8 rounds in it.

I prefer the feel of the Sig P290 in the Micro 9, which is why I use it instead of the 8-round Kimber. I would expect that similar adjustments would work in the Kimber 7-round and 8-round mags for the Micro 9, but haven't tried it. The problem is in the mags, not the guns.

Well, I received the Angle Fire rounds (bullet made by Fort Scott). The package says "Anglefire Ammunitions 9mm TUI 125gr". They are a solid pointed copper defensive round that tumbles upon impact (makes quite a nasty cavity in the testing videos I watched).

These are 125gr and apparently subsonic. The whole intent was to find a round that resolved my occasional FTFs where the nose of the bullet would get hung up on the feed ramp but only when the 7rnd magazine was full. Subsequent rounds always seem to chamber fine.

I did my normal dry testing of 20 magazine loading tests. Took a fully loaded 7rnd magazine plus one in the chamber and dry manipulated the slide to feed the top round of a full magazine in. Then would reload the 7rnd magazine to full capacity and do it again (20 times total). When I would do this with hollow points, I would get 1-2 FTFs out of the 20 and I would also sense/feel 2 additional loadings that "stumbled" a little bit but managed to chamber anyway.

The results for this round were perfect. There were absolutely no FTFs, no "stumbles", everything chambered very smoothly. You could actually feel the increased smoothness of the round being chambered.

I have not fired them yet, but will soon to see how POA/POI is. At this point, I'm back to being "ok" with carrying 7+1 versus me taking my 7rnd magazine and carrying 6+1 (to mitigate the FTFs).


Just a side note... Anglefire is closing out their remaining inventory for this round (normally $22 for 20 rounds, priced at $13 till they're gone). Fort Scott will continue to carry this round though (but at full price).

So I have seen people claim that Sig magazines can be modified to work in a Micro 9. Which Sigs? The P938 or the P290?

The magazine shown above your last post is a Sig P938 Mag. I added some grip tape to it (and the front strap of my micro 9) so that's not OEM. You basically modify the baseplate to fit the Micro 9. It's not terribly difficult. The first one took a little time to do, the second one was much quicker. There's a video below that will give you an idea. The nice thing about the P938 7rnd magazine is the bottom pinky rest "hooks" outward a little.

Another user on here modified a P290 8 rnd magazine (JimCunn) but there's a bit more to it and the end result is an 8rnd vs 7rnd. The P290 doesn't have the pinky hook the P938 does.

The P938 conversion is really easy. I think I did a thread on it. Everyone was doing these conversions early on because we couldn’t buy the Kimber 7rnd mags yet. I like the pinky extension on the Sig mags better.

I modify the Sig P290 8-round mags (I prefer the 'feel' of the modified Sig baseplate to the Kimber 7 and 8-round baseplates). If you mod the p290, the top of the new magazine retention slot needs to be 1.041" down from the top of the magazine. I cut it to about 1.05" and then hand file to the 1.041" dimension. You can make the modified Sig baseplate any shape you want it. 2019-04-04 01_1558800762154.59.15.jpg

Thanks guys.
After Tejun tried my test but also tested a Sig magazine which seemed to perform much better, I think I will try doing a Sig Magazine conversion.

I've watched the video on conversion doesn't look too difficult. But I have some questions: Could you just swap the Kimber base pad with the Sig pad? I suppose you'd also have to switch the spring retainer too since Kimber's is threaded for a screw.

If that don't work, could you just buy some Hogue base pads (made for Micro 9s) and put those on a Sig magazine?

Retention is different.
You are going to wind up moddling the baseplate no matter which way you go. My personal preference is modding the 290 baseplate.

You can get the Hogue base pads and install those on the Kimber magazines. Or if you'd prefer the Sig P938, you'll need to purchase the complete Sig magazine and modify its baseplate. It won't swap over to the Kimber 7 rnd'r.

Quite a bit less work involved with the baseplate mod on the 7rnd P938 than trying to mod an 8 rnd P290. The gun gets bigger with a P290 as well being a taller mag. If that is no issue, that might be an option too with the extra work to modify it?!
