I would like to purchase a rear sight (steel, not a factory plastic one) for my 23. Would like it to be the same height as a factory sight (so I can use the stock front sight, or a front sight of the same height). Would much prefer a fixed/no snag design. Will be willing to pay via paypal or personal check. Flat black/ white dot preferred, tritum OK, but don't want to pay much more than $15-$20. Email is firstname.lastname@example.org. Thanks.
