Looking for a place to have sights and .......

Hay every one.
I'm in Saint Louis Missouri.
I was wondering if any one here knows of a good place to get the rear sights replaced on guns.
I have two that need the rear sights done.
Springfield XD Tactical. Seems back when I bought my pistol Spring field was installing the wrong rear sights on the Tactical model. And you can tell. I have the XDm and it shoots great, I have the HS2000 which is also a nail driver, but the XD is always low.

So I am looking to get it replaces with an adjustable sight.

Also I have a Astra A100 that either needs the back sight drifted or replaced. I think replaced. It is adjustable but it does not hold between range visits. The A100 is basically a clone of I think the Sig 220 or the 226, so I think Sig sights might work.

And I need a place where I can get the Slide, Frame and Grips redone.

Freedom 1911

I came over to the XDm - I bought one last night in 9mm and added some Crimson Trace Laser Grips.
