Got the M213 last week Thursday. Lots of great advise on methods to smoothen this pistol's overall action. Being $99, it is a bit rough. After a general cleaning, manually cycled the slide about 100 times on Friday with some dabs of break free on the rail to help smoothen the action prior to any mods or polishing. Proceeded to the range on Sat. and fired 4 clips of reloads. Fortunately, no FTE nor FTL. Will put another 100 or more rounds this Sat. to observe whether it is continuing to "seat" properly.
Unless one has prior experience with metal work, its best to seek a pro's assistance. Remember that most of the guys who work on their firearms, know what they are doing and possess the correct tools. With our guns, having more metal in the wrong places is much better than having less. This scenario allows for further corrections but it has to be done properly to assure it continues to operate without jeopardizing safety.
BTW, its accuracy was a pleasant surprise. Not as great as a Sig 226 but then again the Sig doesn't shoot 10'xs better (price being 10'xs more). Shoot and enjoy it!!
