Install instruction:

1:install stepped spacer into slide with small end locating in slide opening so that it sits flush with the end of the slide

2:We recommend starting with a lighter spring option and working your way up as needed. 

3:Install spring on guide rod. 

4: hold slide in left hand with muzzle pointed away, use hand to hold spring in place. 

5: Push guide rod in with your right hand thumb until it locates on the barrel lug. 

 

Tuning instructions:

1:We recommend shooting each spring rate to first determine which spring rates will reliably cycle in your firearm based on your ammo type, shooting style and specific firearm and aftermarket add ons. 

2: then shoot each of those spring rates in consecutive 5-6 shot groups at a small target.

3: compare groupings and determine which spring provided the best follow up shot grouping. 

(in general you will most likely end up with a lighter spring rate then factory unless required due to add on parts such as suppressors, thread on comps or other outside of normal configuration)
