Is there anything that can be done about the heavy trigger pull on the LCD 22 mag?
I would think any good gun smith could fix the heavy trigger pull on a revolver with out much trouble.
Actually, any small, lightweight revolver, especially when chambered for a rimfire cartridge, is one of the harder firearms to modify for a light trigger action while still maintaining reliable ignition, and this is because of both the nature of the ammo and the nature of the gun itself.
There are a couple of reasons why the centerfire cartridge became the standard for most ammunition. First, centerfire cartridges are easier to load; second, centerfire cartridges are easier to fire. A centerfire primer , by varying the sensitivity of the priming compound and the thickness of the metal forming the primer body, can be made very easy to ignite. A rimfire cartridge, on the other hand, is limited by the fact that the hammer blow must be sufficient to not just dent the thin metal of a primer but crush the folded rim of the rimfire case. This takes a comparatively heavier hammer blow.
As to the gun itself -- well, think of forging a piece of steel. Sufficiently heated and beaten on a heavy steel anvil with a heavy steel hammer, the steel can be shaped to any form without much trouble. But try the same operation with the same piece of steel at the same temperature, but using an aluminum anvil and hammer, and the difficulty becomes magnified. This is the situation you have with a small, lightweight revolver; not only is the hammer smaller and lighter, and the hammer throw shorter, but the frame against which the hammer works, the "anvil", is smaller and lighter, as well. Thus, a significantly heavier spring is needed to accomplish reliable ignition.
About the only sure-fire way to make a better trigger action in a small, lightweight rimfire revolver is to smooth it up as much as possible -- which can usually be done to some degree -- but actually lightening the action up is courting problems. With the small flyweight centerfire guns, there is a bit more leeway to fiddle with springs, but even with them smoothing things up is still the better route to take any time reliability is the main concern, as it should always be with a defensive firearm.
