trigger job

Do they make aftermarket triggers you can install yourself. The trigger on my model 27 isn't as smooth as it should be.

It's not just the trigger. All the internals have to work properly and together to get a smooth action.
A thorough cleaning and lubrication is a good place to start.
If you're not familiar with the innards of a S&W revolver trigger/action work is a job best left to a pro.
If you do have some gunsmithing experience, Jerry Miculek's DVD will guide you through the process, and most important, warn you away from things that will cause harm.
But, when in doubt, leave it to a pro.

I'll second the above statement. All you really need is a good action tuning, not new parts. In addition, on the older guns with forged hammer and trigger they need to be "fitted" to work together properly, so you'll not only be paying for an action tuning you'll also be paying for a new trigger you most likely don't need.

BTW, tuning the action on these revolvers isn't at all difficult, all it requires is attention to detail, some mechanical ability, and the proper tools. In my case the tools and parts cost me about 180 bucks, however I purchased enough parts to tune at least 10 revolvers. Also spent about 70 bucks on a Lyman Digital trigger gage to check my results. If you go with just the basic essentials it'll probably cost about 90 bucks, a bit more than what a gunsmith in my area charges to tune up a S&W revolver.

If you want to learn how to do this yourself, here is what I consider the essentials. First is the S&W Shop Manual by Jerry Kuhnhausen, it not only covers action tuning but also repairs I personally would leave to a Pro. That Miculek DVD is probably just as good, or perhaps better because it is more up to date, however I don't have one at this point, something I plan to correct at some point. Second thing you'll need is a good set of properly fitted screwdrivers. Third item is a good Arkansas stone or a fine grit diamond hand lap. Then a bit of 800 grit wet or dry sandpaper and finally a 14 lbs rebound spring and perhaps a reduced power mainspring. Personally I've used the factory mainspring and shimed the strain screw using hand made shims made using a Dremel and a diamond burr. It allows me to increase tension on the mainspring simply by removing a shim. I've also used that Lyman Digital trigger gage to tune my triggers to a set weight. For me the end result is 5 revolvers with very smooth actions that feature a 3 lbs. SA trigger and a DA trigger of either 8 or 9 lbs. depending on the configuration. My rimfire and hammer mounted firing pins getting the heavier DA trigger. With the frame mounted centerfires, 8 lbs. has proven reliable after installing an extended firing pin.
