A few years ago I bought an IAI commander pistol to use in IDPA. I used it for about 4 yrs for the second gun match. I liked the way the pistol was trimmed out with the extended safety and mag release, and it felt good in my hand. I liked the way the gun pointed as well. The trigger----that's another story! It was heavy, but even worse it was gritty beyond belief. A month or so ago, I disassembled the lower with the intention of doing some stoning on the action to smooth it up a bit. The inside of the gun had numerous metal chips and grindings along with a substance that could only be described as goo. I cleaned the frame and all the internals with brake parts cleaner and a brush and picks. To keep the internals from rusting I sprayed them with CLP and left them in the sun to dry. I threw the parts in a box and forgot about it for a while. I decided to reassemble the gun the other day before the parts got lost, and guess what? Just by the cleaning and lube the trigger pull weight has dropped a couple of pounds and is almost smoooooooooth. How often do the rest of you guys do a complete disassembly for a clean and lube?
