Part One - Disassembly and trigger stop installation:

Use a bench block to get a solid, non-marring surface against the grip/frame and drive out the three frame pins. Note that on the side of the pistol that you drive the pins from they will have a slight bevel on their outside edge. I have seen two new P-11’s side-by-side in the gunstore with the pins driven in from opposite sides; just note which side yours are on and be consistant upon reassembly for cosmetic reasons. Use your pin punch (5/32”) to drive the pins out and center each pin over a hole in the block to let it fall free. Anytime you are driving pins in/out of any firearm, if you encounter resistance that requires excessive force, stop and look for the reason. The P-11 pins should come out with light to medium taps. To avoid losing small items like the pins, put them in a baggie as they are removed.

Now all that is holding the frame in the plastic grip is the tension of the hammer spring. Hold the frame/grip unit upside down and use a long shaft, flat-bladed screwdriver to reach up through the mag well and press against the hammer spring catch (part 279). Push up on the catch (it takes a little force, as you can see from the strain on my hand holding the grip) until it slips all the way out of the slot it sits in at the mag well rear. Note that in the photo you can see how you must angle the catch slightly to allow it to slip into the mag well.

The frame should come free of the grip with slight upward pressure as shown, if it doesn’t, look and see if the hammer spring catch down in the mag well has bound somehow. Some grips are tighter than others, so you might have to spread the sides slightly to get the frame started out. NOTE THE SLIDE STOP SPRING UNDER MY THUMB IN THE PHOTO (white arrow). If you don’t retain it with your thumb as shown, it will fly off after the frame comes free of the grip. It sometimes comes loose a few seconds after the fact and easily flies several feet. Also, as mine was loose enough to fall out on its own, I like to put a little half-inch square of electrical tape over this side of the Hammer Axis/Pin (black arrow). If it falls out as you work on the pistol, you have to realign the frame and hammer and reinsert it. It’s not that hard, but why bother.

Here's A Tip: That slide stop V-spring will get loose every time. Since you have to put the pistol together and take apart at least once or twice to adjust the overtravel, odds are it will get away from you. My advice is to keep a gallon ziploc bag with your tools. If you put the unit inside before you pull the frame out of the the plastic grip, the spring won’t go far if it shoots out from under your thumb. One of the times I disassembled for the overtravel adjustment, that little piece o’ wire got loose on me and it took 45 minutes to find it. I found it over at our computer desk, inside of a folder of papers.
