Hi everyone. I just registered as I just recently picked up a S&W 99 .40 S&W. I apologize in advance if this is out of place here, but I figured it's close enough to the "real thing", I might as well post here. This is the first time I've fired any P99 variant. The first thing I should mention is I absolutely love it! Out of a majority of other semi-autos I've used, I love how this gun fits in my hands and just points so naturally. The only issue I'm having is with the rear sight. To be honest, I really don't like the rear sight design and am having trouble maintaining accuracy with it. The issue I'm having is the rear sight is wider than the front, so the front site does not completely fill up the rear. I find that, for some odd reason, because the rear isn't completely filled up I tend to point the gun slightly off center occasionally, and it's really making quick follow up shots more difficult (and less accurate) for me. I've never had this problem with other semi-autos. Personally, I'd like to find a rear sight that doesn't have a center section that is so wide. I've been doing a bit of research and see that there are Trijicon, Mepro's, Hiviz I believe, 24/7 ? (can't remember the exact name), a few optical sights, and I saw on Earl's website more of an adjustable target sight. My question is, do any of these other sights have a smaller rear aperture that the front sight will completely fill? The adjustable "target" sight I saw on Earl's website here: Link looks more my style, though these are listed for the P99 and not the P99 AS. I'm a novice when it comes to these guns, so I'm not entirely sure if there is some sort of difference that would prevent me from using any of these sights on my S&W 99. AFAIK, I believe the S&W variant uses the same sights as the P99 AS. I don't particularly prefer night sights over standard sights, however I'll take what I can get if it will eliminate this "dead space" between the 2 rear sight blades. Thanks in advance for any help anyone can give me.
