I just thought I'd post this to gloat in general. I do intend to provide pictures but I only thought of it after the fact and I don't have internet access at home. So it'll take a weekend.
I have, as some of you have probably heard me previously espouse, a Beretta CX4. In 9x19, if you care. I bought a PX4 a while back after discovering that yes, you can get a magazine adapter widget - 20 bucks all told from Beretta for the adapter and mag catch - To make the CX4 take PX4 magazines. So I got one.
The Beretta rep asked me how old the rifle was and I told him it was a fairly early one. He warned me that the "old" CX4's won't drop PX4 mags free even with the adapter, but the "new" ones will. And, unfortunately, he was right. The PX4 mags fit, feed, and function just fine. But they wedge themselves in the magazine well and you have to fingernail them out.
So I lived with this situation for a while but one snowy night not long ago I was bored and decided to see if I could figure out why.
So I took an empty PX4 mag and drew a big spiral around the outside with a silver sharpie, then loaded it up with the upper receiver of the rifle removed. I took note of where the marker was rubbed, and eventually managed to match it up to three points in the plasticwork of the lower where the mag was binding up. What accounted for the bind was the different angle up towards the top end of the PX4 mags where the double stacked cartridges are herded into a single stack... In order to maximize the capacity of the PX4 mag apparently this angle is less pointy and slender than M92 mags. There are two little nubs on either side of the magazine well and a pair of bands that, I imagine, are intended to rest against the sides of the magazine and keep it from wobbling around in the mag well.
Well, M92 mags, at any rate. I imagine the tolerances here are different with the new carbines, but they didn't work in mine.
So, in my truest Bubba fashion, I got out the Dremel and shaved down those offending pieces of plasticwork little by little until my magazines just started to drop free when empty.
And all was good.
