Took my new matte black FNP45 to the range today with a variety of ammo: WWB, CCI BB, and Winchester SXZ (BassPro exclusive?? SWC bullet). All were 230 gr. Roughly 370 rounds were fired between 4 shooters.
The good:
Very light recoil for a .45. While my experience with 45's is limited, this easily was the lightest shooting pistol in this caliber I've tried. I found it easier to rapid fire the FN with all "kill shots" vs my Glock 19 (which I have over 3K rounds of experience with) Better grouping, faster to shoot.
Accuracy-wise, the FN is amazing. All four of us was pretty shocked at how accurate this thing was right out of the case.
The Bad:
We experienced multiple FTF whenever the mags were loaded to 10 rounds. The vast majority of this was using the WWB ammo. When limiting to only 5 rounds, we only experienced 2-3 FTF, again using WWB. (The WWB were not all purchased at the same time, nor place)
When the mags are loaded, you can actually see the bullets lodged in the mags and not feeding to the top. I saved some ammo and will take and post pics. I'll stip down the mags tonight and look for any burrs inside the mags.
I also experienced 3 slide lock failures when empty. I don't have my thumbs anywhere near the slide release button. I assume it's due to too much spring tension.
We also had multiple brass empties to the face. Again, as mentioned here, was probably due to the high slide spring tension.
All-in-all, I really like this pistol. But until I can figure out the mag/ammo problem, it's not gonna replace the Glock at the night stand.
