The stock for the Vigilante carbine is moving right along. I was wondering how to deal with the awkward installing and uninstalling of the stock to change the powerlet. I finally decided to do some more milling and carving to make an opening for the powerlet to just drop in through one of the grips. It's still a crude affair, but the scheme works well. The stock can now be installed somewhat permanently with some recessed machine screws. I'll make a cover for the powerlet slot and secure it with a couple of small NIB magnets that will stick to the powerlet cylinder.

The photo shows the Lithium-ion battery pack and the temperature controller as they will be installed in the stock. I'll make a mounting plate for these devices and do the simple wiring needed to power the heaters. This has turned out to be much easier than what I thought it would be when the original heaters were installed into the pistol frame and powered using a bench power supply.

If anyone is interested in the more technical aspects of airgun ballistics there is a thread discussing the Vigilante in much greater detail here: https://www.gatewaytoairguns.org/GTA/index.php?topic=118339.0

I'm glad you've posted all this information.

I obtained two first variation 357 revolvers awhile back. These are the ancestors of the Vigilante revolver.

I've been planning on installing a replacement vigilante valve assembly on one of these pistols, along with the stronger mainspring to improve performance.

Thank you for your comments. I'm interested in your valve replacement/rebuild. You mention a new 'main' spring. I assume that you're talking about the spring inside the valve. I'm new to airgun mods, so please correct me if that's not what you mean.

Anyhow, if we're on the same page, I'd like to know what improvements you expect to get and how you would go about quantifying the improvement. I've done no spring mods yet on any of my Vigilantes, but look forward to any new paths that could be used to make easy improvements.

When I spoke of the Mainspring I should probably have said the Hammer Spring.

The older 357 valves are not quite the same as the more recent version but these like almost if not all internal parts should interchange as far as fitting into the frames.
Some have already tried the newer valve in the First variation revolvers, and posted that performance was not as good as it should be because they had used the hammer spring that came with the first variation. It was suggested that the spring of the vigilante is stronger or snappier giving a stronger strike to operate the valve properly.

It could simply be that the older 357 springs have gotten a little weak with age.
I have two of the older 357 and each has a hammer spring that is a bit different in appearance from the other, though I detected no noticeable difference in strength of the springs.

The Vigilante valve seems to be an improved construction and stated velocity seems higher than I've been getting with the 357 I successfully resealed and got to working properly.
Velocity is pretty good as is but I'm sure the Vigilante does a bit better in this department.

I much prefer the classic Python type styling of the older 357, which is why I obtained two of these that externally as in nearly new condition with only the most minor wear to the original finish.

I have three freshly resealed 38T pistols , two in .177 and one in .22, these are my favorites. The 357 revolvers are less refined , both less accurate at 20 + yards and lower in velocity, but are excellent backyard plinkers. They have an advantage in being able to use the much cheaper steel BBs.
I ordered some lead BBs to see if accuracy improves.

All interesting, and useful mods. The one that I would concentrate on is the lock-up improvement with the spot welded spacer.
Many think the 6 inch barrel is long enough. Why not offer just the lock-up mod? Or the accuracy mods including the spacer and a better 6 inch barrel?
You will find many more buyers than the 10 inch assembly...
J-B or GooGone?
Tissue test and Q-tips
JSB Exact or LUM-77?
Longer barrel?

Optional 8 inch barrels with shroud are now offered with several of the higher priced CO2 revolvers and the 357 was once offered as an 8 inch barrel target pistol.

George is likely more interested in this being a short carbine rather than a long pistol, or more precisely a pistol carbine revolver along the lines of the S&W .320 which had interchangeable pistol or rifle length barrels and detachable shoulder stock.

PS
I got a tin of GAMO lead BBs and while quality control seems non existent after weeding out the badly deformed BBs I got very good accuracy with these in my 357 and my 38T revolvers. tried them in my new Umarex Colt peacemaker with fair results but in a smooth bore they aren't accurate enough to warrant the extra expense compared to good quality steel BBs.

I've been giving some thought to the idea mentioned above of offering a stripped down version of the Vigilante mods. The idea of just selling an improved latch clip and a machined barrel may indeed have a good following, but I can't see people paying for the setup, machining, and welding work necessary to make the improvements.

Any thoughts?

Basically, its a $50 gun that is pretty accurate as it comes from the factory. Finding the best pellet for my copy plus maybe a reflex sight is about as far as I intend to go. I fixed the lock-up by simply snugging down the hinge screw. It is supposed to be tight enough to keep the barrel assembly from 'dropping' when the gun is opened.
I'm afraid its more accurate than I am.
I agree, its probably not worth it to make a silk purse out of a hog's ear. But somebody probably said that about the 1377..

     I would be interested in the additional details of the accuracy mods and especially the barrel machining as the 4-H club has 2 of these for training the kids to shoot modified Camp Perry style matches, and the accuracy even with good to very good pellets is less than stellar. Remember I'm also comparing the accuracy to a high end Air Arms competition pistol, and a nice Walther Competition pistol, so there is going to be a huge gap there. I may still end up with a couple of Twin Masters, which were the only high end repeaters for  this type of shooting, but I don't know when that may happen, so why not use my lathe and the skills I have picked up making my own bits and pieces to try improving these for the kids. They might not notice, but I will, and I'm the coach!
