What do you get:
Lakeline Stainless Steel Guide rods have a reputation for being tough, really tough!  The Lakeline Recoil assembly is designed to be the last recoil assembly your Taurus GX4 will ever need.  It is designed to be maintainable so springs can be changed if or when they eventually wear out. Fully assembled!  Just field strip your pistol, lube it, and put it in.
With tens of thousands in use, these recoil assemblies have been proven for hundreds of thousands of rounds.  There is simply no more reliable recoil assembly for the Taurus.  No plastic, or thin drawn parts!  The recoil rod is a single piece with the flange,  the most highly stressed part, machined as one piece with the Guide Rod.  If your pistol is jammed from a failed factory or competitor's recoil assembly email our customer support to get instructions on how to get your pistol back apart.
The most proven, reliable and soft shooting recoil assembly for the GX4 Taurus pistols is right here.
The springs are made from the best spring wire available and carefully finished to make sure that they will not over ride themselves or the flanges they ride on.  The Lakeline springs rates are also optimized and provide a smoother recoil pulse than the factory parts while still shooting all standard rounds reliably.  You don't have to select a light spring, that doesn't tolerate heavy loads, nor a heavy spring, that may not cycle regular range ammo with the Lakeline recoil assembly.  By optimizing the spring rates, choosing spring material that doesn't weaken under use as much as typical and using better spring and sleeve lengths, this recoil assembly provides lighter recoil with range ammo all the way to +P rounds.
To make the trigger better, we started experimenting with new striker guides.  We made them in plastic and polished stainless steel.  The polished stainless steel gave by far the most consistent, lowest friction trigger pull.  Our striker guide is precision machined  and polished in 303 stainless steel. You can also feel it when you use the trigger, it makes the pull uneven and nonlinear just before the trigger releases.
The included striker springs are made of high performance spring steel impregnated with silica and copper. The stainless steel one piece spring retainer replaces the two piece plastic retaining cups in the facotry assembly.
Finally, the stainless steel slide plate includes a set screw to lock the plate in place. Given the forces at work when the slide cycles, this ensures everything stays in place.
