LIKE A 2-STAGE GLOCK - RECOMMEND
Project was to upgrade Glock 19 and Trigger action. Total cost of upgrades was $57. Smooth and crisp. 1st step was to Flitz polish all trigger bar parts and moving slide surfaces (plunger/firing pin sear). Deburred and tightened up sear parts via stone. Brownells parts used: *Ghost Complete Spring Set (6lb trigger spring, 4lb firing pin spring, light safety plunger spring) *Ghost 3.5 Trigger Connector *Glock Extended Mag Release *Lonewolf Extended Slide Stop *Rival Arms Extended Slide Lock Ended up using the Ghost Connector w/ the 4lb firing pin spring and the reduced power safety plunger spring. Kept OEM Glock Trigger Spring (5.0lbs) as the 6lb Ghost spring was too heavy (no trigger reset return). Results are a predictable 2lb wall and an overall 4.5lb break. Extended slide stop and lock saves your thumbs and fingers for the Gen 3. Glock Ext Mag Release works great with the edges rounded off a bit.
Ghost spring kit
I converted a Glock 23, 40 sw to a 9mm. Fired numerous rounds of Speer CCI bulk 9mm and my reloads, with no problem. After getting the gun sighted in. ( needed a taller front sight. ) I took it to the range to fire duty type ammo, to check function. Numerous miss fires/ light primer strikes. I replaced the firing pin spring with the Ghost 6 pound spring. and 6 pound trigger spring. The gun now functions with any ammo I tried. I highly recommend these springs for anyone who CARRIES a Glock.

Did this with a rocket 3.5. Best trigger ever hands down. You can spend easily 5 times that amount for a trigger KIT. and yours would require more force more pre and post travel and have a lesser reset. Do this and nothing else!
Excellent / Beware Light Primer Strikes
It is important to note that the Ghost Spring Kit comes with TWO Firing Pin (aka Striker) Springs: a 4# REDUCED spring and a 6# INCREASED spring. (The Glock factory original is 5#.) Combined with an Overwatch Precision Trigger, the overall triggerpull weights in my Gen4 G21 are 3.5# with the Ghost 4# spring, 4.0# with the Glock original, and 4.5# with the Ghost 6# spring. I am using the Glock Factory original firing in spring, for a triggerpull of 4.0#. (I doubt that the firearm would be reliable using the 4# Ghost Firing Pin Spring.) I had TWO failure-to-fires using new Winchester milspec 124 NATO cartridges in an only-slightly dirty G34 using the Ghost 4# Firing Pin Spring. The pistol had fired 600 rounds of commercial 9mm cartridges the day before and was cleaned overnight. Then I fired 300 more commercial cartridges followed by 150 of the 124 NATO. There were TWO failure-to-fire/light primer strikes with the 124 NATO. The firing pin channel had no noticeable fouling. 124 NATO has hard (milspec) primers. I removed the 4# Ghost Firing Pin Spring and replaced it with the Glock Factory original. Triggerpull went up from a very light 2.75# to a still very acceptable 3.5# but with the increased reliability I require in any of my firearms. (They must go "bang" with any and all ammunition, including milpec or foreign brands with hard primers.)
very nice upgrade to glock
very nice and cheap upgrade for glock for under $10. I bought this without the 3.5lbs disconnector as I polished everything myself already. Using the springs does reduce the trigger pull by 2-2.5lbs(my trigger pull gauge is not good, so I only can tell how much it reduced, but not the exact weight it's at. :( ). The only thing, as others said in the reviews for the complete kit with 3.5lbs disconnector, is that the 4lbs striker spring does cause light strike(use factory striker spring is fine). However, in my case, it might also be the fact that I have been using the hard russian primers. I may try federal and/or cci primer to see if I can use the lighter striker spring later on. for now, I am very happy already and will order more for all my glocks. for $10, it's a no-brainer.
Complete spring kit
Easy to install…trigger pull came down 1 pound
Great for the money
Great to have around in your range bag in case you need a rapair. Recommend it 100% except the trigger spring. That one seemed to make the reset sound awfully mechanical, and laboring for the weapon, but would work in a pinch. Already going to order another one when I place my next order. Never have enough spare parts.
