Comments on my P6 experience:
As I understand it, it is and is not a 225. Mechanically the same, fit and finish not the same. It is a military/police pistol designed for ball ammo.
1. My first 2 did not like my hollow point defense ammo, was only about 94%, 200 rounds and 98.5%, 150 rounds, reliable. My 9 other 9x19mm pistols shot and shoot it 100%, over 8k rounds total, 5 were/are Sigs. (The odd wording means not all are still with me.)
2. My current P6 is 99.3% w/ that hollow point ammo and 100% with ball, so far (200 hp, 100 ball). This is my keeper, at least for a while. I’m going to try some other brands of HP defensive ammo, maybe PowerBall.
3. It has a heavier double action trigger pull than current models. The DA pull is noticeably heavier than my 228 and much heavier than my 229. Nice single action trigger. (Sorry for the subjectives don’t own a trigger scale.)
4. The ProMag I have is a 7 and 1 mag. The follower engages the slide lock on the 7th round about quarter of the time leaving the 8th in the mag. The follower is hollow plastic so I can’t just cut it down without more work than I’m willing to do. Don't recommed them.
In closing: I like um, want one, got one. It’s mine. You can’t have it.
It would be a good single column/small grip, some like the grip better than the 239, self-defense pistol, IF you find a reliable defensive round for it. All three were accurate enough for me, 3x5 card at 10 meters slow fire. Gad I hate getting old. My P6 is not going to replace my carry guns. It will be another fun 9 and you can’t have too much fun. For self-defence you might be better off with a used or referb 239, 228 or 229 at more money with less work but then you won’t have a P6 like mine.
That’s my opinion and worth just what you paid for it.
