Walnut PPK V2

Hi. First off, thanks again to all the purchasers of the original Walnut PPK. (Or PPK/W, as someone noted.) Reading comments on this board, and evaluating what I had built, I've decided to go ahead with a second version. I have walnut left.

This second version exists in four (almost finished) prototypes I'm building to test concepts, get jigs built, and will have the following features:
• more detail
• movable trigger (for trigger pull practice)
•• the trigger in the prototypes is made from polymer clay. It should be stronger than wood, and is certainly (with my woodworking skills) more repeatable. I thought about cast aluminum.)
• rackable slide. I don't know exactly how far the slide racks on a real PPK, but it's certainly a satisfying action to pull the wooden one back and have it slide forward into place with a little click.
• hammer. Non-working, probably polymer clay like the trigger, and mounted in the slide.
• sights.
• removable magazine. Held in place magnetically. I've made both flat and finger rest types.
• movable mag release. Non functioning, but it can be pressed.
• safety. Haven't done this yet, so I don't know if it will move or not. Probably not; I can't figure out a retaining mechanism.

Here's an out of focus picture of a prototype slide, in poplar, unfinished, for an idea.

Comments are welcome.
