All sizes of our precision machined overtravel bearings. 4 total
Find the perfect size bearing for your frame and trigger shoe. 
Installation instructions: Start off with the second smallest bearing, if that works and the trigger breaks, move up to the next size. If it doesn’t work and the trigger will not break, move down to the smallest size which will work will all shoes.
Note: if the trigger won’t break you can manually break it by inserting a small punch on the right side of your backplate opening and apply downwards force on your sear thus dropping your striker. You will be able to remove your slide once the strike has been dropped. 
Or you can remove all your pins but the method above is faster and easier.
