Sorry man. He was giving you a hard time because your font is huge compared to most posts. That's all. Just ribbing you a little. It looks like you are yelling with that sized font.
Anyway, in answer to your question, no I have not tried the two finger rest. I don't believe in making a small gun significantly larger to increase capacity. If I wanted more capacity, I would have bought a full size P30. However, out of curiosity, I did get a +1 finger groove extension from HKparts.net. It works fine, but it does affect the way the gun points. Pulls the point of aim down a bit if you grip it too tightly.
I ordered two of the +0 competition mag extensions from HKParts.net. I like them, chose them over the shaped billet finger rest version. It gives enough purchase for the pinky to rest on the mag and full use of my hand for control of the weapon.
ETA: Just returned from a night shooting class with the P30sk. As mentioned above, the two mags with the +0 extension were controllable and accurate. The third mag with the stock baseplate did not give any purchase to the pinky. As a result, I missed multiple shots during drills.
I installed the +2 in about 5 minutes and went to the range yesterday with my crew. Feels great, no malfunctions, and it's a quality piece of machinery (but I guess it should be for $22). My very small "complaint" is that I wish it sat a bit more flush or tightly against the bottom of the mag well frame (see pic) but it's really a minor picking. Use with no apprehension OP. Stay safe.
Just installed the x2 today. Agreed with the aesthetics - wish it were flatter/more fitted to the grip. But works well. Here's a pic of the 10 rd mag with a P2000SK plate, an X-Grip on a 13 rd mag, and the HK Parts x2 grip. And a very very unscientific measurement of the height of the pistol with the 3 different floor plates. Again, very unscientific.
