Good. Maybe you actually managed to find a Ruger .45 that didn't have the barrel crushed to buggary. Most are .002 to .005" crushed at the threads.

If you got a "minus" pin gauge set the pins will all be a couple of "tenths" under their mark.

I did and they do. I checked a few with my mic. Very consistent.0002” under the number etched on the pin.

Don’t get the gun wet.
Isn’t it nice to have friends?

You'll find the pin gauge set quite useful. it's one of the tools that doesn't get used often but when it's needed man is it ever just the ticket. Where they can be misleading is in an out of round hole. Place the largest pin that will fit in each throat and hold it up to a light, any out of round will show right up.

Misleading if you aren't paying attention, but extremely useful for determining roundness which is as important as actual size.

I use ball gauges for measuring cylinder throats. A good Starrett set will set you back more than an inexpensive set of pin gauges but will tell you more about the hole, for example taper (and how much), out of round (and how much), but there are some things they won't reach....like revolver barrels at the frame unless tje barrel is really short.

Got a set of Starrett small hole ball gages and telescope gages left over from when I worked in the shop before I started programming. And 3 sets of ID Mics to 12". Now those don't get much use inside a revolver bore!
