Prototype Cocking Aid for the Predom Lucznik

Cocking the Predom Lucznik results in an incredibly uncomfortable sensation of the front sight trying to tear a hole in your palm. The Walther LP53, which the Lucznik is patterned after, was supplied with a cocking aid. If you look at this German page, scroll down to the picture showing how the LP53 is cocked with the aid attached. So I decided to make a prototype out of plastic.

A chunk of Nylon rod faced and chamfered before cutoff.

A brass rod, 1/4" diameter, chamfered before filing the end to a half round.

The two pieces fresh from the lathe.

The plastic was tightened up in the vise on the Taig mill and the centerline was found. I milled a flat across.

I then drilled slightly undersize for the brass pin.

Next I pocketed it out to clear the barrel and front sight.

The pin was pressed into the hole.

It covers up the front sight and makes for comfortable cocking.

This is what I'll change in the future - the pocket doesn't change width, I should have narrowed it where the sight is so that it can't twist from side to side. Only after I made it did I find an end on view of the Walther one in an auction on Gunbroker, showing the narrowed slot width. I'll be making the next one out of wood, when I get a blank disc made by my friend Rudi, the wood turner.
