I really enjoyed my SR9, and I wish I still had it.
I have posted a few times recently that I bought an XD and that I feel like that is the perfect polymer pistol for me and I hold to that. From experience shooting all the major polymer players, the SR9 is my second choice. And, hopefully, the compact version will be coming home soon to take up it's new role as my concealed carry auto.
Honestly, I really don't dislike any of the major polymer guns in 9mm. the XD just sort of suits me the best is all. I have minor quibbles with all of them, but on the whole, I am pretty much a convert when it comes to polymer pistols. Get into .45, and that opinion changes somewhat, and I am simply not interested in the .40 as something to add to the "need ammo" list. There are certain guns I like in steel in 9mm, but for the most part, polymer is the way to go for me.
