I was going to suggest the FNP45 as well. I haven't got to shoot mine yet, but I bought one right before coming back to the 'stan and loved the feel and the controls, etc.. Do all FNP45's have this issue you speak of?
My original High cap .45ACP was just buying the 10 round extended mags that gave me 10+1 in my 1911... Can't remember who makes them. Bought them in the Las Vegas Gun Store on vacation and they work perfect. If it's home defense, you can get those ridiculously high cap 1911 magazines like FPS russia uses in a couple of vids. lol (I prefer Shotguns and 40 round magazine AK's for Home Defense, myself...)

In addition some of the fnp models have feeding issues especially with Winchester white box.It's not 100% sweeping, but it's common-- at least in the production runs that account for mine (and all of those prior). I believe mine is... 2 years old?
I found the issue on a forum somewhere, and immediately rushed to my pistol to have a look. It had eaten about 600 rounds at that point, and the pin was visibly walking. I drifted it back into place and decided to keep an eye on it.
I gave it a 1k work out across the next couple of weeks, and it walked again. I decided to leave it until it became an issue, just as a test. About 300 rounds into the next session, the trigger wouldn't depress and drop the hammer; the pin had walked out so far as to impinge on the frame.
I tapped it back and started looking for a fix. There was none, but horror stories abounded about trying to get FN to take care of it. Looooong waits, the wrong parts being sent out, etc. I thought of staking the pin, but there's basically no material there to work with-- and some of it is plastic anyway. Someone considered Loctite, much like you'd use on press-fit sights that were a little loose, but found that it was ineffective-- no matter what type they used. (Guy even tried the green...)
Then someone mentioned that they had drifted it 2 or 3 times and it suddenly stopped moving. So I kept on shooting, drifting; shooting, drifting. In the meantime, a friend brought his out for a couple of days of training and within 1k rounds (it was brand new), his gun locked up. I drifted mine once in that time frame as well.
He reports one more instance of drift, and then it just stopped moving for him as well. That was 5k rounds ago, way back in May-- so it's probably more by now. I haven't shot mine much since then, but it still hasn't made it past 1500 before it was dangerously close to locking up. It's gotten that far out in as little as 300 rounds t'boot.
For several reasons, I switched to the aforementioned M&P with TF basepads for the role the FN was supposed to fill and haven't thought about the gun since then. For all I know, there might be a fix out there-- DIY or from the factory. Something worth investigating if you plan on running the thing hard for extended periods.
