I had my local shop install a set of Meprolight night sights on my G-30SF on Saturday. When I got home I was reading the paperwork that they gave me, I noticed that the sight model number was ML-10224 and it said they were for 9mm, .357 Sig, .40, and 45 Gap. I looked it up on the web and the proper sight number should have been ML-10222 for the 45 ACP and 10mm. I called the shop and they said they had installed the wrong sight, but it would work fine because the only difference is in the length (not height) of the front site. I intended to call Meprolight to ask them, but they are in Israel, quit a long distance call, so I E-mailed them but I have not received a response. Any ideas from someone who might know would be appreciated.
