Is the titanium firing pin still in the slide? Is that the interference? Yes. And it seems to function normally. I can feel spring pressure resistance if I press the rear of the firing pin and the tip of the firing pin then emerges from the face of the slide. Release pressure at the rear, firing pin tip retracts. Seems normal. As the firing pin retaining roll pin has been removed, I guess the tip from the broken punch as taken its place. The disassembly videos on YouTube show the firing pin is not under a lot of pressure by the spring. Removal of the firing pin retaining roll pin in the videos usually results in the firing pin fall out and not at any risk of flying across the room. Those same videos also show the retaining pin pushing through after a few light taps with a gunsmith hammer. This leads me to suspect that the hole in the slide was undersized or not concentric, or my 3/32 punch was oversized along the shank. But I am just guessing. A gunsmith would be ideal but I would not scoff at a machinist who has been faced with removing a stuck, stripped or broken screw once or twice. The good news if the broken punch is accessible from either side of the slide. It isn't tucked away behind another part or at the bottom of some deep hole. It just will not respond to the impact I can apply using the tools and tips available to me. I'll make a fresh attempt at locating a gunsmith/machinist/exorcist after the holidays. I am anxious to report the problem has been solved before Squawberryman wrecks his blood sugar with Milk Duds. |

A machine shop could probably do it, but the problem with them is that they are reluctant to work on guns and I can't blame them. We have a big ball bearing plant in my town and I needed to get a rifle receiver rockwelled as I knew they had the rockwell machines. Being good ole southern boys they were glad to do it. My question is I wonder if a machine shop would punch it out or use a press.
I've had many stubborn pins, but alwasy managed to remove them. My hardest was a pin holding the rear sight on a 1938 Italian Carcano Carbine. I pulled some of my hairs out, but I eventually got it out. I hate to sound like a parrot, but having the piece rock solid is part of the key to getting it out.

Get a bigger hammer.
Seriously.
A small, light hammer going fast might yield the same KE as a larger, slower hammer, but the larger hammer will have more mass, contributing more to momentum to overcome the inertia of the "object at rest."
Peening? Use a smaller hammer with a lot of light, fast taps.
Making something MOVE? Use larger hammer, slower velocity, usually ONE "tap" if you don't get crazy with it and don't get too meek about it.

Use larger hammer, slower velocity, usually ONE "tap" if you don't get crazy with it and don't get too meek about it. The problem with the bigger hammer is the exposed shaft of punch becomes the weak link. I need a punch with a short, tempered shaft or it's likely to bend or break before the stuck tip moves. I never heard from the gunsmith I contacted. New plan is to bribe a friend I know who owns a machine shop. His place has everything from Bridgeport to Fanuc machines, a hydraulic press, mills, and every measuring device known to man. They build parts for industries that require very precise tolerances on tiny parts. A lot of their final QC inspection is performed with a loupe or under a microscope. I approached him about this earlier on a day when he didn't have sufficient time to study the problem. We tried punch/hammer and even the hydraulic press but I think we did not have the slide secured well enough as it begin to turn under pressure. I will take another run at him after Christmas when things are slow at his shop. Lots of good ideas offered here and I appreciate the feedback. I will provide an update when I have one. Merry Christmas! Hugh |

"a punch with a short, tempered shaft"
That sounds to me like you might want to get a punch called a nail set. You can find them in various sizes at any hardware or home improvement store. I keep a few different size ones with my other punches just for the reason you are discribing. Small tip, large tapered shaft, with some decent mass. Then the bigger hammer might just work.

As long as this thread is getting, maybe it will rust out! Guess we could schedule a BBQ. Bring a dish and a piece to showoff, and everyone try there hand at "gettin'er out" 15 minute time limit and a prize to the victor? |

For what a couple briskets and fixin's costs now, it'd be cheaper to buy a new gun!

attempted to remove the firing pin for inspection using a 3/32 roll pin punch By this do you mean a hollow nosed rod pin punch? |

Kind of a sword in the stone, King Arthur sort of thing. He that removes the pin from the peashooter is worthy. Kroil hasn't helped. Maybe BBQ sauce? |

These have the rounded button on the end to fit inside the roll pin without collapsing it. That part worked. The pin did not collapse. The punch, however, broke even with the side of the slide and refused to turn loose. |

Kroil Oil is damn good stuff. I consider one of the things that it is, is a penetrating oil. It is not a friction penetrating oil. Yes I know I said that wrong. His punch tip is stuff from friction. I have high hopes his machine shop friend will get it out.
