A while back I got on a kick to get another J-frame for reasons. I think J-frames are changed significantly by adding a bit more grip, so having an extra one so my 638 could keep its boot grips made sense, at least to my twisted brain. And I thought it might be neat to have a companion to the M60-NoDash that was my dad's, about the only cool gun he didn't sell late in life when he went all-in on camera gear. And I snagged a 637 on sale when they had a rebate so I think I paid only $275 before the transfer.
Part of the plan was to try and put on the XS Big Dot that "requires" milling. A friend helped me do my 638 and when we were done it seemed like it woulda been easier to just file the thing, so that is what I did on the 637. Somewhere along the way I sold something to somebody and had some frivolous cash and I took the plunge on a 360PD, and that sorta stalled my progress on the 637. But now it is done and I think it turned out well and is pretty neat:
It has the sight, Apex kit and Altamont grips. If I photograph the right side you can't see the lock...
Here are some views of the sight:
The view on the left shows the basics of the filing, at this stage I was probably 85% done. It took longer than I expected but was a fun project. I tried the "matting" with a file and hammer but couldn't get it to look the way I wanted so I went back to stippling like I did on the 638.
Anyway, I feel like I have "owed" this thread some pictures, and here you go
