Trigger enhancments,

Hi All, I
New to this Form , Have Bought Myself the SD9VE, Like Most and feel the Trigger is .......Well, Needs improvement, First off I'm a Certified GM tech and Not a Gunsmith But Have Been In the Automotive Business for over 40 years, I Have several Firearms and Most will get the same Treatment That I perform on them , The SD9 Model suffers from Casting Slags Mostly in the striker system , if you remove the side and work the striker by hand, you will feel the crunchiness of the striker, The trick is to remove the binding , you remove the striker assembly ( if your are the kind of Guy that will stab yourself with a screwdriver then This is not for you, )

You will have to remove the striker cover off of slide , Tools Needed , Small Jewelers set of screw drivers, , 3 punch set, small set, assorted , Finishing sandpaper , 400,600,1000,2000 if available 1000 should do the trick, 400 and 600 to clean surface's,
Insert small Tip of Flat tipped to remove striker cover , it will slide down , May have to Move Bushing forward, , Just a little,
Remove spring , watch out for small collets Don't lose them , remove plastic slide bushing that The striker is in, Note you will see two or black lines inside of Bushing assembly, Put off to side for later, we'll get back to that , Take a look at the striker, On the end which goes into the Bushing , Run Your finger tip along the edges , you will feel Machining or stamping Marks, The trick to remove those edges , or really just clean them up, so it does not binding the bushing , only remove enough so you do not feel the burrs anymore, It does not take much, polish strike pin assembly with 1000 only NOT THE POINTY END!!! leave it alone!!! put off to side,
Back to Plastic Bushing , If you have a Jewelers loop you can look inside where the lines are that where the Crunchiness came from The striker was digging in to the plastic, Lightly clean up with 1000, also smooth out the Outside of Bushing too,
The bushing should slide in and out , of upper slide, No binding, it should not be tight , if it is tight it will choke the striker , (My Taurus PT 111 G2 had this Problem But Worse! Now smooth as silk!!, That's another Forum But same Idea, ,
Take some White Ultra fine Polishing compound and Mobil 1 on a Small Artist Brush, Small amount coat inside of bore , and Plastic bushing , reassemble and Make sure it Moves freely, , Complete assembly and test You should Feel it Immediately, if done correctly , You can test just working the striker inside the Upper slide, No more crunchiness, This works for ALL STRIKER fired, Fine out where the stamping Burrs are and remove them ,
If you are braver then you can do the same with the trigger system , its fairly simple design
