One thing i personaly disliked about the SR9 was that the slide is kind of a bear to pull back. Grated i had just cleaned a couple guns and had some residue from my silicone cloth on my hands...
My first impulse pistol purchase was a M&P 45c. Things started of a bit shakey but it was entirely my lack of skill. I also talked myself into thinking it ws too big to carry. After some training and getting a good IWB holster along with a gun belt, I absolutely love it.
I also bought a LCP for those special circumstances were i need deep concealment, and a Glock 19
because 9mm ammo is really cheap. Which is definitely nice when a training course requires you to bring 500 rounds. Sometimes i do think i should have bought a M&P 9c but i like the Glock too! Probably end up buying one eventually anyway.
