My gosh. So I just bought a used XDM 5.25 competition in .45acp from a guy on gunbroker. I was pretty tickled with the price, and the guys at the Pawn Shop (ffl) agreed that I stole it, but when I got home and took it apart.......... I think this guy must've gone straight from the gunshop to the range with it and shot the dirtiest ammo possible. After scrubbing for a while it got to where the chamber loaded indicator wouldn't come back down because there was so much crap in there. There was so much carbon on the extractor that I am amazed that it was still working, if it was. I finally soaked everything in bore cleaner then transferred it to some steaming hot water in the sink. You wouldn't believe the size of the chunks coming out of that thing. Anyway, after a couple rounds and a lot of toothpicks (I like to use toothpicks to get the corners and knooks rather than metal picks) I finally have the sweet pistol I thought I was buying. The sad thing is that the seller probably thought this was a horrible gun, I can't imagine it ran very well. It really looked like somebody way over oiled it and shot a lot of rounds through. If he'd only taken the time to clean it, maybe just before selling, he might've realized the problem. Anyway, my plan is to replace the barrel with a .460 Rowland. That way I can still shoot .45acp, but switch to .44 magnum power whenever I need/want to. Seems like the best of every world to me. One thing that will need to be addressed is the trigger. I have an XDm9 that I put in a Powder River Trigger kit into years ago and guess I am spoiled. The new guns trigger feels very spongy with a really long reset and over travel.
