Mine is great. Thousands of rounds through it, no malfunctions of any kind. Wipe it down often and no rust. It was my 1st XD (and 2nd--later sold the 2nd to fund Sub Com. .40), Now have one of each, 3", 4" and 5" all in .40. I shoot the cheapest .40 ammo I can find, Ultramax reloads, 180 gr, conical nose lead bullets and have yet to have any malfunctions with any of the three. UltraMax avail from SG, mailorder--$147.00/1000. Accuracy is highly adequate for 10 yard practice.
