Pistol grip def goes to the AR. The AK pistol grip was very small. I don't know which one felt more balanced to tell the truth. Thats why I think I am just going to have to pick one and learn.
When I got my 1st pistol I had no idea what I was looking for and based my decision completely off others reviews. Now that I am more experienced, I can actually feel the difference b/w a crappy trigger and a good one, a gun that points naturally for me, etc.
Similarly, I think it is going to take more than just shouldering a gun to know how it feels b/c I don't know how it is supposed to feel at this point. The differences are scuttle enough (or my ignorance is great enough) that in my inexperienced hands I don't know the difference. That said, the short stock on the AK made me feel like I had to bring it in very close to me opposed to the AR
