Opening up a rear sight aperture

[Roddy]

I have a non restricted CX4 Storm in 9mm that I like except for one thing. The rear right sight aperture (hole) is ridiculously small. There are actually two of them and they are both extremely small, especially for a pistol caliber firearm. The "close range" sight on the No.4 Lee Enfield was way bigger and more useful.

I am thinking of drilling it out to a larger size. Has anyone else done this or something similar? Anything I should keep in mind like bevelling the hole or something? I know I could put a red dot sight on it but I would like to make the sights it has usable. If I like it I may even do the same to my Colt SP1.

If it were useful the girlfriend could even use it for keeping coyotes out of the yard as it has very little recoil but as is it is you really can't even do that.

Thanks in advance.

I'd would not drill out the peeps, the day you go to sell it you have reduced its value. Mount a red dot on that rail and you'd be good, even a Bushnell TRS-25 would do the job.

Thanks for the reply Wester. I have thought about doing that but then to use it a person has to make sure it has batteries, turn it on, adjust the brightness, etc. It kind of takes away from how handy a non restricted, box magazine loaded, low powered, Uzi style carbine with a ten round capacity could be.

I would like an Aimpoint so it could be on all the time but that's a lot of money for something I will probably never use much. Maybe after tax returns next year.

Turns out rear sights are $5. I ordered a spare one and I'm going to try it.

Yeah no big deal to open up the rear sight. Even a little diamond round file and open it bit by bit until you're happy with it.

You could even go as far as turning it into a ghost ring sized rear aperture, but keep in mind without a nice round front sight hood, or a large bright front sight post to index it off of; it might not be all that accurate.
