total disassembly of a SIG slide

2ndchance · November 9, 2008, 03:08 AM

I'm planning on refinishing my Sig P225/P6 slide. I would like to break the slide town and remove everything so I end up with a gutted/hollowed-out slide. So, here's my question.

1. When drifting the sights off the slide, does it matter which way I tap them (left or right)?

2. When I press out the roll pin in the back, will this allow the entire underside (holding the firing pin and breech face) slip out or is there something else in there holding onto it.

I can only relate my experience I am not a Sig armorer.
1. Sights are removed right to left. The rear will be on very tight. Don't mar the slide in an effort to hold it tight in the vise.

2. The roll pins are what hold the block in. Same as the sights right to left for removal. Get new roll pins from Sig they are not the same as what is avail at the hardware store. Place the roll pins so that the splits are opposite. You must use close fitting pin drivers for removal. Some say to remove the inside pin first. The pins are tight. When putting the pins back in I use a purpose built pin driver. Its holding hole is made just for the Sig pins so that the pin is supported about 1/4 the length and is somewhat compressed as it is held in the pin holder.
Good Luck.
Lots of info over on the Sig Forum.

Aw.. so you think I can't reuse the original pins?

I don't believe there is any reason not to use the original pins of they don't get boogered up.

I agree. However, if the pins are loose fitting going back in, get new ones.

Also, as stated, use the proper size roll pin punch not just anything that will fit in the hole. This will prevent boogering up the pins. A bench block (steel block with various sized holes drilled thru) will be very helpful in driving out the pins.

Roll pins can be reused, but never on a service weapon. Service weapons must be 100% reliable. Roll pins lose their compression if used once. That's why they're never reused on a service weapon.
