About 6 months ago I too joined the Combat Tupperware Brigade. As a former short-time Glock owner, I didn't like the way it fit my hand and lack of positive safety features. I dumped it. They might be good guns, but they are just not me.
After a few years of carrying my faithful S&W .45acp, I decided last summer to get a lighter weight .40 for easier summertime carry. I actually did some research and testing to see what worked best for me. It came down to a S&W M&P, or Springfield XD .40 sub compact. I chose the Springfield. With factory night sights, it was about $200. obamabux cheaper than the Smith. Both are fine guns and either way, I would have been happy.
