I have a P9 Ultra (40s&W), and it appears to be IPSC approved or authorized on the roll mark on the slide. I also have a witness 10mm so I can compare and contrast the two guns. The springfield P9 has a much nicer finish, better sights (from the factory) and front cocking serrations. The witness is rougher finished, almost parkerized, lacks the front cocking serrations and has the front of the slide cut more like a high power. Both are exceptionally reliable, easy to clean and quite accurate.
I sure wish I could chase down another P9ultra. I would buy it in a heartbeat.
By the way, both are made by Tanfolgio, new Tanfolgio mags work fine and EAA support is great for the P9. Springfield will even recommend EAA if you call for support. Also other then the external finish, the fit and quality of the parts appears identical, even though the guns were purchased several years apart.
Get a p9 if you can find it, otherwise get a witness.
