Thanks everybody for the replies.

First off, Pawpaw, many thanks for showing me what a stovepipe looks like!

I used totally incorrect terminology in attempting to describe my problem. It's definitely not that. It's not a failure to eject issue at all.
Mupepe, good question. The failures to feed are recent developments. I've shot hundreds of rounds through the gun using the 2 mags I have for it with no issues. The mags are factory Colt Mark IV Series'80 Government Model - 380. One that came NIB when I bought it(new) at the Original Fort Worth Gun Show back in 1984 or 1985. The second one I bought a few years later. Both Colt mfg. And it's only started recently. I'm thinking it's the mag springs. I'd go out & buy a new mag to test it out, but that gun is so old, replacement mags run about $35.00 and I want to explore the fix it alternatives first.
Thanks rotor, will do!
Zombified, many thanks for the uTube link! That's what I was looking for but couldn't find it. I tried that same method of disassembly before I posted the OP and couldn't get the follower out. Will try again. The follower is not like a standard 1911 mag follower. It's got a hump in the middle of it and shaped differently.
Flightmare, yes it's only in the last 2 rounds of a full magazine. When I insert a fully loaded magazine into the butt of the gun, rack the slide, it jams because that bullet is caught on the curved lip of the magazine. Nosedives right into it. It doesn't even make it to the feed ramp.
I remember several years ago, I wanted to try out the Winchester Supreme elite PDX 95 gr hp's, and it did the same thing. Jammed on the first round. I switched to Monarch 95 gr hp's and had no problem with them.....until recently.
Thanks everybody for your input. Appreciate it!
