Another Frankengun question

[JohnHL]

Just an FYI, my 915 and 5906 (built just before the billboards) slides do not interchange.

Not to dispute your word, surfgun, but I can't imagine why those two slides would not interchange.
Mine do like they were made for each other.
However I realize there are exceptions to the rules at S&W.
I would like to learn, in the interest of all things S&W, where the areas of mechanical conflict arise between your two examples.

I re-eximined my 915 and 5906. The slide of the 5906 does work on the 915 frame. On the 5906 frame, the slide stop will not go in with the 915 slide, the barrel does not cam down enough to allow the slide stop to go in.

Thanks for trying again, surfgun!
I sometimes forget that the concept of interchangeable gun parts is limited by the accuracy and consistency of the production machinery and operators. There are always tolerances. And when those tolerances inevitably "stack-up" somewhere in a series of thousands of products, it results in the occasional unexpected incompatibility.
Perhaps a little rearward pressure on the muzzle as you insert the slide stop will make it go. It might take three hands, but sometimes that works for me.

Let me throw something out........ IIRC ......after the "Tactical guns" came out some autos had heavier/beefier /"box rails" that were associated with the early hand built PC guns.......

That's interesting!
Are you saying some standard (non TSW) models (like the 5906 for example) were built with TSW rails instead of the standard rails?
If that is so it would certainly explain the one-way interchange.

Well, whatever the necessary alignment of stars is ... I haz it.

The latest from the lab: S&W 3906 with a Smith 915 slide. Feeds and ejects dummy cartridges with no problems a't'all.




I'm debating keeping the two-tone look, Ceracoating the slide something else (for protection or looks) and/or having the slide milled to accept a regular 3rd Gen fixed sight.

Me likey!

I think the two tone look is neat.

 

[BAM-BAM]

I like reverse two-tone ....... I'd say round the trigger guard an cerecoat the frame matt-silver/stainless.

Again IIRC; yes........ the heavier box rails started on the PC guns then the TSW........ and then all.......vaguely remember some threads and pictures.... about transitioning from what was learned from the early hand built PC guns to the factory guns........ why have two slide designs???????

The frame sure could use something. It looks like it was dragged behind something along an ugly rocky road....

I had never thought much about it - this is the first I've had - but I'd have to agree. I kinda like it!

I didn't care to much about two tones until I got my 4567, now I'm hooked.

You've just opened the door, gunhobbit!
There's a whole lot more to see inside.
