SIG front sight removal/installation
As an experienced armorer certified by numerous companies, including for SIG classic line and the 320, I find the SIG front sights to be the motherb*tch of all. I can use my Kaiser Uni Tool to take out and install regular height sights with moderate difficulty, but with suppressor height front sights, it is ridiculous.

The Wheeler sight tool is useless for SIG front sights. All they need to do is cut the pusher to where it would actually fight the tiny shoulder on the SIG front sight.

After beating a sight like a redheaded hooker on a P320 Pro, it took using a large diameter drift punch that fit the entire shoulder of the sight and a dead blow hammer to get it in. The left side of the shoulder showed some damage which was disguised with some cold blue.

The rear sight? Not a problem with the Uni Tool, but the Wheeler tool was useless as it wouldn't budge it as the pusher bracket would torque and had to be knocked straight enough times for me to say screw it.

Any tips from ones that can make me slap my head like Homer Simpson? DOH!

I would suggest trying a different sight pusher. I've used this one on all of my 220's and my 320 and it's worked on both the front and rear sights. Some of the 220 sights I've changed have been 15+ years old and it pushed them out with ease.

I've been watching that one on eBay. How is it for suppressor height sights?

Sorry, I don't know about that, I've only put on Siglites and a few other brands.

Remember to oil the threads of the sight pusher before trying to move the sights.

The sight-tool.com device above works pretty well but you almost need an extra set of hands to make the adjustments to secure it. I've used mine on standard sight height SIG and KIMBER pistols. I made padding for the sides and top of the slide from strips of adhesive backed fuzzy side VELCRO.

Also, put a drop of oil under the sight(s) before you crank on it.

I clean and lube the sight pusher before each use. The suppressor height sights are too tall for this tool. I need a punch that is sized properly to install the front sight.

I run them on and off with the Rear Sight Tool (RST). It works fine on front and rear sights.

I have several brass punches that I shape as necessary to fit the application. Also, some sights need to be reduced somewhat with a file.

I've always used hammer/punch on all my Sigs, classic and P320's. I found the Dawson Precision front sight tool ($3.95) works well, especially for the P226 and P229 front sights (shallow bases).

The punches are aluminum and can be easily filed to size. Also, no risk to damaging the dovetail or sight,since they are softer. Buy a couple, since they will eventually deform.

I use a nylon/brass drift for the rears. Hammer/punch method REQUIRES a heavy padded vise on a solid bench.

I have a collection of the MGW sight tools. There is never any issue getting sights installed.
