Installation Difficulty:
Improve the crispness and feel of your trigger while adding punch with the Lakeline precision machined Striker Assembly.
This fully complete assembly is drop in ready and includes Lakeline designed and manufactured:
- Precision machined 17-4 Precipitation Hardened and polished SureFire Stainless Steel Firing Pin (striker)
- 303 Stainless Steel Striker Guide
- 303 Stainless Steel one piece Spring Retainer

- Stainless Steel rear cover plate with set screw for enhanced retention and safety
Drop in installation.  Unload your pistol, visually confirm it is unloaded. Field strip the slide off of the frame, remove the backplate and pull out the striker assembly, replace it with the new assembly.  Reinstall backplate and put the slide back onto the frame. See additonal notes below.
Additonal background:
In the stock trigger you can feel the uneven and nonlinear pull just before the trigger releases.  Replacing plastic stock striker components with precision CNC machined and polished stainless steel gives a consistent, low friction trigger pull.
The Lakeline Firing Pin is precison machined and uses the high performance precipitation hardened stainless steel that is electro-polished.  This firing pin is hard nosed and will give you lasting, impact strikes.
Some companies aggressively market titanium parts for firearms in the name of weight savings and there are application where that significantly higher cost makes sense. The Lakeline SureFire Stainless Steel Firing Pin weighs less than 0.2 oz, about the weight of 2 pennies; we don't think doubling the price of the firing pin is worth making it weigh 1 1/2 pennies. Titanium also readily deforms and has low elasticity compared to stainless - which means you will have to replace it more often. We prioritize high quality performance at a reasonable price.
This assembly is compatible with the Taurus GX4 Series, including the GX4, GX4XL, and GX4 Carry. 
It is NOT COMPATIBLE with the G-Series and the TH Series handguns.
