Trigger Pull Video
Flat trigger makes the break more defined\harder. With apex sear seems to break earlier. Snap break no matter what striker is used. Definition of break changes with striker used, shooting sight being the lightest and apex the hardest. Apex/Edge striker has very slight creep shooting sight has none.
Apex trigger adds creep and softens the break no matter what striker is used. Pull/break is very sloppy when used with a stock sear. Rolling break for apex/edge striker. Light snap break with the tiniest hint of creep with shooting sight striker.
Apex striker = Adds noticeable pull weight no matter the configuration. Would only recommend if you don’t have the edge striker and would prefer a rolling break.
Edge striker = Paired with the apex trigger/sear is the perfect setup for people who prefer a rolling break.
Shooting sight striker = Is perfect for people who prefer no creep. For a more defined break use with stock trigger for a softer break use apex.
I finally got around to testing all the combinations of parts that I have. Full mcarbo spring kit installed. Parts/springs have been polished except shooting sight striker. I don’t have a regular 509 striker so I wasn’t able to include it in my testing. Used a wheeler trigger scale pulling on the lowest possible point of shoe. Sorry I didn’t do a more detailed test of the components like take any measurements for distance of takeup/creep or marked the trigger guard with tape to see pull length, etc. Hope this helps everyone!
ST = Stock (LS Edge) Trigger
AT = Apex (Flat) Trigger
SS = Stock Sear
AS = Apex (Updated/Jagged Edge) Sear
SSr = Stock (LS Edge) Striker
ASr = Apex Striker
ShSr = Shooting Sight Striker (Long Tail)
ST+SS+SSr = Soft wall with a rolling break. Trigger seems/feels like it breaks earlier in the pull. 2lb8oz
ST+SS+ASr = Defined wall with slight roll/creep before break. Break also seems/feels earlier in the pull. 3lb4oz
ST+SS+ShSr = Most defined wall with a snap break. Very similar to the same combination but with the apex trigger. Wall seems a bit more defined and break seems/feels earlier in the pull. 2lb12oz
ST+AS+SSr = Feels/seems like less takeup/pretravel. Defined wall but softer than same setup with Apex Striker. Slight roll before break and break seems/feels earlier in the pull. 2lb6oz
ST+AS+ASr = Feels/seems like less takeup/pretravel. Defined wall but softer than the same setup with the stock sear. Slight roll before break and break seems/feels earlier in the pull. 2lb14oz
ST+AS+ShSr = Feels/seems like less takeup/pretravel. Snap break with no creep at all. 2lb12oz
AT+SS+SSr = Defined wall with a rolling break. Similar to the same setup with the apex striker except a lighter pull weight. This also seems to break all the way towards the end of the trigger pull. 2lb14oz
AT+SS+ASr = Defined wall with a rolling break but with more resistance/weight. This setup seems to break further towards the end of the trigger pull. 3lb6oz
AT+SS+ShSr = Has the most defined wall and a snap break no creep/roll at all. 2lb10oz
AT+AS+SSr = Rolling break with a soft wall. 2lb10oz
AT+AS+ASr = Rolling break with a more defined (still soft) wall and less creep. 3lbs
AT+AS+ShSr = Snap break with a very slight hint of creep. 2lb8oz
