Replacing/upgrading the safety plunger in the Glock can smooth and lighten the trigger pull. Trigger pull plays a huge part in accuracy. A lighter and smoother trigger will enable you to keep the sights aligned and on target.
The LS Titanium safety plunger is smoother, rounded and coated with Titanium Nitride to reduce friction/tension. This is the best safety plunger available.
The great thing about Glocks is they are very easy to work on. Replacing the safety plunger will only take about 5 minutes and anyone can do it.
