So the foundation is laid. 5” 45 ACP
Caspian standard frame;
Remsport slide;
Storm Lake gunsmithfit barrel;
EGW grips safety;
EGW slide stop;
EGW link and pin;
C&S thumb safety.

The frame-slide combo has its blessing and short comings. Laterally the clearance worked out to .0005” - .0007” front rear. Not as much fitting as usual was needed to the frame and slide in that direction. However, vertically the ckearance is .0025” without any fitting! I didn’t get too bummed about since the barrel lockup will take up the clearance.

The Caspian seemed to be their oversize dimensions. This is my second Remsport slide. The first is the one I buikt my 9mm on snd it was definitely oversized. So the jury is out until I measure the Remsport slide on the shelf for the next build.

I’ll check in as work progresses.

Bottom of beavertail ready for final blending after test firing. The frame/gripsafety seam is prolific because I knock the edges off the beavertail. This prevents rolled edges and abraded hands.

Looking good, are you planning on lighting cuts on the frame under the grips?

No, I won’t be doing any intentional lightening to the pistol.

Mainspring housing blend, this time the housing was below the frame’s lower surface.
Knocking off a speed reload pinch point. Looks elegant, too.

Little bit more done…that’s a relative term. The trigger itself has over an hour and a half on it. The polish on the back of the bow smooth out disconnector/trigger interface during pull and disconnect. The divot you see was to reduce lateral movement to the left of the pistol. It is actually a takeoff from another pistol and was slightly oversized for this one. Sometimes things work out.

The last pic is how I load the bow to the bottom of the track to determine how much fitting is needed at the bottom the the top of the pad.

Hammer and sear, Cylinder & Slide and Thunder Mountain Custom respectively. The sear is hard…about 52 RC! Hammer is coated stainless and no slouch in RC rating.

Sear:
Sides spot smoothed, before and after pics;
Disconnector and sear spring interfaces smoothed;
Primary angle cut and secondary cut;
Face intersection broken.

Hammer:
Hooks set to desired depth (this IS a very nice hammer);
Hook tip corners broken.

Sear spring, TMC.
Corners already smoothed but hit it with a stone anyway;
Cutout between leaves deburred.

Still under construction. First, how little I had to do to fit the EGW high shelf magazine catch. The first two I used were definitely oversized. This one was oversized just right.

Next up some fitting I did on the slide stop. Again EGW, lots of fitting but a really nice result.

The mainspring housing smoothing and blending preparation for stippling. Yes, the housing was checkered. Rear of frame preliminary contouring and smoothing. Housing rails peened and fitted.

Stippling layout and a new design experiment. I’ll need to grind a couple stippling bits for this attempt.

Nice work. I use the Thunder mountain springs and other parts in my builds. Good quality.

Tended to the stippling. Sometimes the DNA is undeniable.
