I've had a PF9 for a couple years now. Good concealment gun, but that pinky wrapping up under the magazine rather than around the bottom of the grip really effects quick presentation and follow-up shot speed.
I ordered two of their 8rd extended mags recently. Just got them today.
Wow.
Totally different gun once you can put the pinky on the bottom of the mag. Yes, it adds half an inch to the gun's height. But that's the point, for me. Just a skosh more controlability, try and bring it on par with something like my XD9 subcompact. And with this 8rd mag, the height of the gun appears to match the XD9sc when loaded with a 13rd doublestack magazine. But it's much thinner than the XD9sc, obviously. And lighter.
I have yet to get out and fire the new mags. I will do so in the next couple days.
One of the problems I have with my current 7rd magazines that I hope disappears in the 8rd ones: When I load 7 into the mag, I carry the gun in a 6+1 configuration. If I carry in 7+1 config with the 7rd mags, the first round to follow the one in the pipe always experiences a failure to feed. However when I carry downloaded one round, no issues. I think the mag spring at full compression slows down the slide just enough to hinder feeding that first round. It's my hope that Kel Tec uses the same spring in the 8rd mag as they do in the 7rd, being that they sell the conversion kit to turn a 7rd mag into an 8rd mag and it includes no alternate spring. As such, in a longer configuration, there should be less spring tension on the topmost round in the mag at full capacity, and I can then carry the pistol with 9 rounds total rather than my current 7.
