My bad! Windage yes, elevation no. I was thinking in comparison with 4", 5", and 6" GPs. Elevation adjustment is what I miss.@waveform
Are you sure?
Everything I've read about the Wiley Clapp GP says the rear sight is windage adjustable (by loosening the set screw according to one website).
Great info - thanks! I was looking at a new 3" GP today and the top strap of the frame looks like a scaled up 3" SP101. There is the raised ramp with the center milled out and the radius notch at the sight end (if that makes sense). The 4" and 6" I have are flat top frames as is the Wiley Clapp I have. My guess is they use the same frames to start with for WC as are used for 4" barreled models and longer. The WC version gets different dovetails for the Novak sights and the other special stuff that goes into the WC version.I didn't realize the frames were different between the 3" and 4". Yes, there are a number of adjustable wedge-profile rear sights that fit Novak dovetails. The one in the hyperlink in my original post is from STI, and is my preference. Novak also makes one called the Adjustable Extreme Duty Sight, Caspian used to market one, but it may actually be the STI one. Kensight sells one.
OK - I think I'm starting to see your dilemma. Since you're doing the conversion to 10mm you can't just buy a different GP, you need to stick with the fixed sight frame 4" you have. I wonder if the top of the frame could be milled down flat and then a dovetail cut?I sent an email to David Clements to ask if it was feasible to do this conversion. His only response was, "Not really." I'm guessing it's not something he wants to take on rather than not something that can be done, but much can be left to interpretation with such a vague two word response. Guess I'll have to contact Jim Stroh when I get the GP100 back from David. Would have been nice to get all the work done at once, but I've been wanting to send work towards Jim at Alpha Precision for a long time.
Bummer. You'll still have a pretty unique 10MM GP100. And there's always next time.....and have a 10MM conversion done on a Wiley Clapp. That'd be pretty cool too. (And I realize that brings us back full circle to where you said you didn't want to buy a Wiley Clapp.)I spoke to Jim Stroh at Alpha Precision. He's not comfortable removing as much metal as a Novak dovetail would require; he feels it won't leave sufficient strength in a GP100 top strap. He did recommend looking into the SPI Tactical adjustable sight if I do find someone willing to take on this project. Not looking to good for this project.
