Why not compare fictional firearms used in sci-fi books, too?
I mean, once the 'vaporware' guns become actual firearms, then they still need to be Beta-tested for 1-2 years before I'd be willing to invest in one, let alone consider using one as a dedicated defensive weapon.
On that note, diminutive size pistols chambered in the common defensive calibers need to demonstrate a high level of consistency when it comes to reliable functioning in order to be considered for dedicated defensive carry weapons. It sometimes seems that doesn't happen until a couple of years after their initial release. Then there's the potential ammunition sensitivity issues to consider in some reduced size platforms.
Personally, I don't like to consider firearms which haven't seen at least a reasonable amount of attention and usage by LE/Gov users. Those folks can come up with creative ways to abuse and break firearms which can sometimes confound engineers with their originality. Make a pistol which can withstand the abuse and attention of cops, and then you can brag about it.
Never handled a PF9. I have, however, seen more P11's fail to complete a 36-round qualification course of fire without functioning problems occur than I've seen pass one.
The last PM9 I handled and fired seemed to feed & function fine when I was shooting it, but the owner (another instructor) eventually got rid of it because it didn't demonstrate consistently reliable feeding for him. I didn't care for the characteristics of the felt recoil & controllability, and I definitely didn't care for trigger, but it was his gun and he just wanted me to try it for a while one day.
The PPS shares some characteristics with a platform I appreciate and respect when it's chambered in 9mm, which is the P99 series. It seems by listening to owners that they've probably outgrown their teething pains. I haven't asked anyone at Walther America about them because I already have a handful of excellent 9mm's which are only marginally larger from a practical perspective when it comes to my pocket/belt holster carry methods.
I don't see any firearms on that list that really meet the considerations I use at this time. At least not yet. The PPS might come closest ... but I'd want to run 300-500 rounds of some different defensive loads through one before I thought about spending my own money on one. Dunno yet.
While I'm offering opinions, I suppose I might as well say that I dislike lower abdomen/appendix carry almost as much as I do SOB carry methods ... so the whole Smartcarry consideration wouldn't come into play for me.
Just thought I'd share, anyway.
