Re: lead bullets in xd 45 acp
I also have the four inch XD. I have a couple thousand rounds through mine, so the recoil spring has relaxed a little.If the round count on yours is low, that could be a contributing factor to stoppages.
I also deep cleaned the gun and then polished all sliding/rotating surfaces with Tetra grease. This stuff gets into the pores of the metal and you can actually feel the action smooth up after using it.
I think a combination of a "broken-in" spring and slick action allows my XD to now reliably digest low-end loads. I know a lot of folks over on the XD forum who can't get SWCs to feed reliably, and quite a few who shoot them without issue, so it's obvious that the pistols vary in some area critical to proper functioning with square-shouldered bullets.
