Genuine Glock® 21SF or 20SF OEM Gen 3 Trigger Group from Marine Gun Builder. I guarantee 100% this will fix your PF45 trigger problems. Every kit is personally assembled by me and will come ready to drop into your PF45 frame.

 

MGB solved the dead trigger for Polymer80. Each trigger kit is tuned and tested for First Time Quality.

 
These are the 4 components that make up the G20sf or G21sf Trigger Group. For PF45 frames, if you are using anything but this setup it will likely lead to problems. You may need to modify the OEM housing to compensate for P80's mis-molding. Video walk-through download link will be included with a free assembly course code in the package - takes just a few minutes to fix.
 
If you need a full lower parts kit for SF models please see the listing in the store. For standard (non-sf) full kits message me if they are not active in the store and I will create a kit for you.
 
Most of the G20SF and G21SF kits have the wrong parts. These are the latest updated parts from Glock. All other trigger component setups will sit to low in the frame causing dead triggers, failure to reset, and poor sear engagement. Whether you choose MGB as your OEM Freedom parts provider or not, you must insure the trigger assembly you use includes:
 
(A) The latest G20/G20SF G21/G21SF Trigger from Glock - It is stamped 4256-3 on the cruciform. This is the one you want. The originals sit too low in the frame causing a failure to return to battery and many other safety issues.
 
Every Patriot who chooses MGB for their Freedom parts will receive a code shipped with their purchase for a Free Self-Paced Frame Assembly Online Course at Freedom Crew University.
 
 
MGB Guarantee:
I individually inspect each package for first time quality. When you buy from MGB, you are buying Authentic Genuine Glock® products assembled by a Certified Glock Armorer.

      Instant Fix

      Exceptional customer service and the response to my questions were answered fast. Just like the product states it is a guaranteed fix. I mistakenly used a LW lower parts kit and the trigger assembly was prohibiting the slide from fully going onto the PF45 frame. The one time it did go on the trigger was dead. After reaching out to MGB he reassured me it would fix my problem. Upon delivery I installed the first time quality part and just like that my problem was resolved.

      If Marinegunbuilder says it'll work, it'll work. This gentleman diagnosed and prescribed a fix to my build issues in minutes and without charge. I obviously bought the parts from him which were high quality and fully assembled. PF45 's take a G20/21SF trigger housing and bar period. Parts dropped in and were smooth as butter.

      Smoother trigger pull than expected! This did fix the issue my pf45 was having - the trigger connector was not contacting the striker. This trigger module sits perfectly in the pf45 frame to get that striker contact and smooth follow through. Highly recommend this for 10mm pf45.
