So, I am fairly new to Springfield and I decided to get an XD-S for my first. Can't say it was the best experience. I loaded some training rounds and they fed just fine, but when I threw in some Hornady Critical Defense it would get stuck in between the slide and the feeding ramp EVERY TIME! I sent it back to Springfield and btw, they have awesome customer service! (But I'm sure you guys already know) They cut and polished the feeding ramp along with other things and sent it back drenched in oil. When I loaded the first Hornady it jammed once again, but I was being gentle. As soon as I used my big boy strength to rack it, it fed just perfect. Now I have no problems! Didn't know springfield was such a rough B*tc*!
