Sig Sauer P230 inner pin stuck (plugged with broken punch) - How can it be removed?

I will make this as short as possible. Purchased a very well used Sig P230 in stainless version and decided to disassemble it for a thorough cleaning job as I usually do with used firearms. Parts came off with quite easily until I went to remove the pin from the slide. I used a 1/16" Starrett pin punch and tapped the inner slide pin (Part #49 inner pin H.D according to parts diagram) in order to remove it. After quite a few taps and dropping lubricant on the pin it would not move. Hit it harder a few more times and it did not budge. Tried pulling the punch back out and it was stuck in the inner pin. Unfortunately after moving and twisting the punch slowly it broke off and left a small piece stuck in the pin. Went and tried on the other side and the same thing exact thing happened. I tried hammering with another punch from both sides, but this thing is really stuck and now the pin is plugged on both ends. I did not want to drill it not having a proper drill press. I do not have a hydraulic press either.
I have been able to do this with no problem on all my other Sig Sauer pistols but this was the first one I had a problem with.
Now for the questions.
The breech block can be removed from the P230 canít it? With the inner pin being plugged on both sides with a piece of the punch plugged on both ends what would you recommend would be the best way to get this removed or just leave it? If it is left the way could this be dangerous when being under pressure while firing?

Drill press, appropriately sized cobalt drill bit to remove only the broken pin punch ends, maybe a couple thousanths of pin (Which will need replacement anyhow) center and square very carefully. Never try to remove roll pins with under sized punch again.

I've used a Dremel drill before on roll-pin-broken-pin-punch problems that find their way to my work bench.

Thanks for the reply. But as for saftey goes it wouldn't be a problem if just left in there? I was only thinking of pressure build up.

It's probably not going to hurt anything.

Hey sorry to hear about your mishap,but I was thinking if the punch hasn't flared the inner pin (putting pressure to the outer roll pin) to much u might be able to put a socket on one side of the slide get a propper sized punch and a big c-clamp and with a lot of lubercant try to slowly press out the inner pin. just food for thought before you go drilling anything hopefully the punch that's stuck isn't hardened steel if u do have to drill it out.

Thanks again for the advise. I have a dremel with a flex shaft attachment and I am thinking of getting a few tungsten carbide drills to see if I center it and drill it out slowly. If that does not work I will go to the gunsmith and see what he says.

Well I was able to remove it. Bought a diamond bit for my Dremel and also a carbide drill and drilled it carefully until I was able to get a punch in and knock the rest out. Waiting for my replacement pins now to re-install.
