Does anyone know of a way to reduce the DA trigger pull on a S&W Sigma, model SW9G? We bought it for my wife and she likes it, but I think she would be able to shoot it better if the trigger was a little lighter. I haven't been able to find a spring kit for this model. Any help would be great. Thanks.

Try contacting Wolff gunsprings directly. Perhaps they have something that Brownells goesn't carry.

A problem with the Sigma trigger is that the striker spring is the load, and lightening that lightens the firing pin force. If you adjust the spring to a nice triggerpull, it won't fire a cartridge.... Perhaps a careful adjustment to the sear angle can lighten it, but my experience with a Sigma was needing help with a few more fingers to pull the trigger after a few rounds.

gunnut69,
You were right - Wolff has a reduced power striker spring, 3.5# vs 4.75# for the factory spring. I guess Brownells doesn't carry it. Thanks for the info.

Great!! A company can't carry everything. Since this is a defensive weapon, be certain it is absolutely reliable with the ammo you choose. Some ammo has harder primers than others..this can lead to misfires from some brands.. Also treat the interior surfaces with a dry lube. They will allow parts to move eaasily and yet will not gum up the action..

gunnut69,
I've used the Remington spray on Dri-Lube before, but it seemed to disappear quickly, so I went back to using Snake Oil (from Dillon). Is there another brand of dry lube that you would recommend? THe SW9G is a nice gun except for the trigger pull. I can shoot it well, but the heavy DAO pull is a problem for my wife. Hopefully the new spring will do the trick. Thanks.

Actually I've been experimenting with a mix of my own. Powdered moly-graphite in a solvent carrier..mineral spirits right now. The carrier evaporates leaving the dry lubes in place. Not a new idea but it seems to work. Used it on a Remington trigger assembly that I'd cleaned(it was full of gum). It dropped the pull weight(by scale) nearly 3/4 pound. It also didn't leave a gummy mess to attract dirt and unburned powder.. I use a product called 'Lock Ease'. It is graphite in a volatile carrier.. When the carrier leaves the part is dry and slick with graphite, a high pressure lube. It does not protect from rusting..
