[QUOTE="LouBoyd, post: 596003, member: 9253"] There's a section on the magnum research website about identifying the different models of Desert Eagles. Yours is probably a Mk VII or Mk XIX but could be a Mk 1. The lowers are nearly identical, the barrels are an slides are differeent between Mk VII and XIX. The MKXIX slides are heavier as they were introduced to handle the 50 AE but they changed all calibers. The manual you can download has parts lists for all models. If the bolt doesn't close completely the most likely problem is gummy lubricant. Normal cleaning doesn't get to the parts behind the bolt. Download the manual and read it carefully on how to disassemble and reassemble the bolt. The MRI cleaning kit helps but other tools will work. I would suggest you clean and lubricate the bolt before you shoot it again. It the bolt has galled in it socket it could require replacing parts. The fact your DE is hard to open is also a sign of a gummed up bolt as the bolt has to rotate to unlock. Don't take the trigger mechanism apart. It can be washed with lighter fluid to remove gunked up grease. I use Tetra-gun grease lubricants on most of my firearms where there are high pressures and tetra oil or Rem oil for small moving parts. Both are teflon based. but there are many that are good. Most lubricants will gum up if they set unused for years. I clean and re-lube all guns I haven't shot on a two year schedule. When you re-assemble your DE look carefully and you should see that the main "recoil" springs are double, one inside the other and spiraled in opposite directions. The outer spring is heavier. Make sure that all four springs are present and not broken. If your DE started it's life as a 357 it might not have the proper springs (2 instead of 4) That's a much less likely problem than gummy lubricants but easy to check.
