I love my P227 Carry SAS Gen2. Fit and finish are just as good as any of the P220s I have had. Mags are expensive and it carries (size and weight) the same as the M11-A1 I got rid of. I must confess due to the width of the short double stack magazine the pistol is not a joy to practice/shoot one...
I have not shot the MK25 but I do love my M11-A1. You will find prices vary pretty good on them depending were you go, so shop around. I am finding that most holsters recommended for a 229 are also recommended for the M11. The slide is heavier than the 228 so watch out on fitted/kydex holsters...
I am a SIG and HK guy, so I got all excited when the P224 came out. That excitement tuned sour when I actually held one.
I cannot even remotely get my 2 bottom fingers on the P224 and extended mags on a subcompact seems to defeat the purpose.
The P30SK looks a little longer in the grip but I...
Edited: My comments were for the recent railed Beretta 92 Compact so they will not apply to older models.
I loved mine, DA was real smooth with the D spring. But I traded it in on a Sig M11-A1 because I need night sights on my pistols (especially carry guns) due to working the night shift...
I have never shot a FNX or the P227, but I am on my 3rd P220. Lots of flavors (depending on what you want to spend) but I kind of think the P220 sets the standard for a DA/SA 45acp. I encourage you to rent and shoot one before buying and I would bet once you do you will compare other 45s to it.
I bought mine in 2001, can't kill it. I put night sights on it awhile back, HK locally did it.
You can also swap out just the barrel and make it a 357sig.

I have seen the barrel cheaper on EBay.

Being that it is science and not sworn on a Bible, I do hope some...
