where can i get a half round punch to disassemble a 2011 sig p229 slide.looked about every where and out of stock or discountinued.

.

If you can't find this punch, I suggest you call Alex at AB Prototype: www.ABprototype.com

When the company was located in San Diego, Alex made a couple of P320 slave pins for me. I use the slave pins to remove and install the complete Striker assembly as one piece into the FCU vs. installing the sub-components inside the FCU one piece at a time.

If you can't find one for sale, it might be easier to make one yourself with a round punch and a file.

Looks like it would be easy to make with a disc sander or grinding wheel using patience not to overheat

thanks everyone.probably will make one.

having made several if you have access to a mill its trivial. Second best is a bench grinder. IT will be a long project with a file.

^^^ This.

A lot of us trained in some mechanical arts pick up the previous generations solutions - because there was no such tool available to them. Didn't mean they couldn't fabricate it.

I have a small collection of one off tools to fit certain difficult applications. They are slowly piling up in a tool box drawer, I sometimes look thru them to remember what the problem was. Wrenches bent with heat to a special angle, or ground to fit the first 9mm nut I found on a car that was half SAE and half metric. Fairmont/Zephyrs forced that.

For an older generation, the bench grinder was the Dremel of it's day, with a wire wheel on one side it cleans up a lot of small parts.

I was able to make my own, using a 3mm punch that I ground down. It works great!
