Of course both of you are dead on in saying that the 46m's grip is a disaster. It lasted approximately 20 hours in my hands (had one previous owner who used it at the Canadian Airgun Grand Prix this year, and he did a couple of trivial bits of wood removal, basically leaving the grip as it was from the factory) before I started carving and adding epoxy putty. I am, and have been since 1986, a luthier, more commonly known as a 'violin maker' although I actually specialize in working with doublebassists. I have made many knives, planes, and other tools, and have no difficulty working in wood and metal. Saw the Baikal grip as raw material much too small for my hand but useful as a platform, a model towards a real grip. I've twice added putty, and the thing now fits my hand like a very nice custom made glove.
Of course it's ugly, and the putty will never be attractive... even with a coat of black paint. But it gave me an opportunity to experiment over the past week or two, especially with rake. I modified the mortise such that the grip was able to tilt back 7 degrees, a figure derived from analysis of about a dozen photographs taken during various dry-fire shots. I would aim with the rear sight at the target, ignoring the front sight and barrel angle, until I found an angle of wrist-to-grip which provided optimum wrist lock without excessive strain. I plugged the lower screw hole and drilled for a bolt from the heel at the location of the lower end of the grip retaining tang. Then I drilled from the non-used side for a 3/8" brass rod which I drilled from the rear and threaded for the bolt. Shooting has only improved since this modification, bringing my average up approximately 1.7% in a week.
So this afternoon I've started work on a grip exactly like it, carving it from a piece of wood left over from making a new neck for a bassist two years ago. I've found an end of this 'scrap' which suits ISSF dimensional guidelines well, and leaves over a piece perfect for making a copy of my wife's 17th century Venetian violin, something I've been wanting to do for years. I've only cut out the blank so far, but after taking my kid out to the woods for a few hours this afternoon I'll get to work shaping it. Gorgeous piece of flamed big-leaf maple, aged about 15 years. I'll likely stain it with aniline dye before doing a linseed oil rub, just because it would get too dirty looking if left blonde. Will post images on CAF, maybe here too, if anyone's interested when the thing's done.
This grip will of course use a more controllable mechanism for rake angle. The Baikal grip was just a simple test. I'm going to use a single large Allen bolt from the rear as before, but this one will have a machined groove and a retaining set screw with plastic bushing from the non-used side. This will reverse the action of the bolt on the aluminum grip tang, into which I will install a brass bushing with threaded hole, and making an oblong vertical slot for small angle changes from bolt head to tang, enabling fine adjustment of angle should I ever wish to change it. Of course this will prove useful when going from my home maximum range of 7m (with appropriately scaled targets) to an official 10m range with same-height targets. Should be about a 1.5 degree change I should think, easily changed with a small turn of the bolt.
I will of course be fitting the mortise more accurately to the pistol frame than Baikal has done. There's is surprisingly sloppy, with almost 1mm on either side showing as a gap. Should firm up the feel of the pistol slightly.[/img]
