A lot of people have been asking about a way to make the MK series slide return home by racking it. I have accidentally found a very crude solution. Recently I lent my friend my MKII and he lost my left side thumb safety. In the process I also lost my plunger spring. Now I can rack my slide to get it to return home after a slide stop. The gun works totally normally otherwise, I tested it out at some games yesterday.

You can remove the impact buffer from the recoil guide rod on the MKII to power stroke the gun as well.

Neither method works with my Mark 1.

Removing the buffer washer causes the pistol to lock open as the lip on the hammer catches the underside of the slide.

The problem is the "slide lock notch" (for want of nomenclature) on the Mark-series is too big and the slide can't retract far enough for the front edge of the notch to bump the slide lock back down.  What KWA was thinking about when they did this I've no idea other than perhaps the follower isn't strong enough to hit the notch when the mag is empty -- larger target.  See the comparison to my 9mm Government Model below.  (The "small" notch is the same on all M1911 pistols, this one was just the handiest right now.)

Making the notch smaller is well beyond my mechanical skills but seems to be the solution.  I think someone glued something in theirs this summer but have lost the thread.
