Im in the market for a sub 9mm. And the xd is one of the picks on my list. Just a couple of questions. Does springfield have there rust issue takin care of Ive heard alot of people have rust issues with there slides. And Ive heard of the locking blocks and some slides cracking in the 40 s&w model. does this pertain to the 9mm also. I dont mean to ramble on just gathering as much info before I plunk down my hard earned $$$. My other choises are kel-tec p-11 the cz rami and the kahr cw9. But the kt and spring field are within my budget. By the way how does the little xd conceal in the summer under a t shirt. Ill probably use a iwb holster. Thanks for the time on this subject. Shoot straight and be safe Dan..
