Im looking to get a few pin gauges for my 38/357 and .44mag.
I dont want to buy a whole set just a few for each caliber that will allow me to determine my cylinder throats of each. So what range would you buy for each? .??? to .???
Im going to order some from Meyer Gage Co. I think.
Would 3 or 4 for each caliber be enough? Want to keep cost down.

I bought a whole set of meyers - pin gauges on ebay for less than $100. Shop around. You may find a deal. I always find new uses for them.

Ok thanks for the reply.
On their website they have .0760" to .50099" this would work right? looks like its $14 would be good for .357 and the .44

I know exactly where you're coming from but Wheelguns1961 is right, look for a cheap deal on a whole set. It still might be more than you want to spend at the moment but in the long run you'll be glad you did it.

I think that $14.00 is for each pin gage, not the whole set!

lol yeah you might be right. Im a cheap ******* so looking for the least amount to spend is ingrained in me lol But you guys are probably right like always and I should just buy one cry once.

My set starts at .251” and ends at .500”

I have all sizes from .011 to .500. The .250 to .500 is the most useful. I think I paid around $70 for my .250-.500 set from ENCO, which is now MSC. They are on sale often. Get the whole set. If you do regular gunsmithing or shop work, where measuring hole sizes is needed, the whole set will get used at some point. Buying a group individual pins is cost prohibitive.

^^^^ THIS^^^^^^^^^^^^^

A bit of shopping, and you will find you spend less in the long run. Often,, it can take 3-6 pins to figure out a hole size. And if you have more than 2 calibers to tinker with,, a set is MUCH cheaper in the long run.
Let's say you THINK you need just 3 size pins each for 2 calibers. That's 6 pins,, at about $10-$12 each, plus shipping. Then you discover you need 1-2 additional pins,, and a second order has to be made.
You just exceeded the cost of a set.
Or,,, later on,, you decide to add a 3rd caliber to your collection. Now,, you need 3-6 more pins. Again, exceeded the cost of a set.

I bought a set years ago,, thinking initially the same as you,, but knew I had more than 1-3 calibers to play with. I bought a .250-.500 Minus set. Now,, when I open the set,, I have almost 1/2 of the pins unwrapped,,,, and have used them,,,, KNOWING I saved money by buying the set.
And remember,, not only can you determine throat dimensions,, they can also help determine thread choke.

Bite the bullet so to speak, & buy a set.
Heck,,, if you want,, you could possibly sell the really odd ones & recoup money on the set too.

Get the whole set. You can use them for different uses including verifying your micrometer/caliper is calibrated plus revolver cylinder throats, pistol chamber dimension, etc.

Ok ok ok you all got me to change my mine and I'll get the whole set, man peer pressure lol. So what a "minus" set and is there a "plus" set?

You want a minus set.

Minus set! I have several set that go from around .05 to 1". I use them for lots of stuff in my machine shop, not just gun stuff. Guns stuff is just a sideline hobby for me.

Get the whole set that incorporates the sized you will need. You will find lots of uses for accurate pins!

I bought this set off Amazon.

My set looks like that, but I bought from Enco or MSC with and discount and shipping coupon and it was around $80 I think, maybe a little more. It's been a while, though.

For simply measuring cylinder throats I find small hole gages better suited for the occasional user.

https://www.amazon.com/DGOL-Full-Ball-Small-Range/dp/B078WLFKXQ/ref=sr_1_6?crid=1VBMOOW3T6ZRJ&dchild=1&keywords=small+hole+gauge+set&qid=1589771923&sprefix=small+hole+gauge%2Caps%2C163&sr=8-6

Pin gage sets come in various grades and steps in addition to plus or minus.

For standard usage ZZ are the most cost effective. Same for size steps. The standard ZZ sets are on .001" increments.

Lots of folks use them to calibrate mics without understanding how the plus or minus works. Using a .500 ZZ class minus gage the true size is .4998". On a plus .500" ZZ class the actual size is .5002". The class will determine the tolerance on the plus or minus however it will never be over size on a plus or undersize on a minus.

With a minus ZZ set and a plus ZZ set you can check a .0004 difference in the best case and .0006" in the worst and with only one set you are limited to .001" steps.

Individual pins and sets can be had in a whatever size sets you want. I have two ZZ set both minus .2515-.5005 and .251-.500 plus some individual pins.

Bottom line is with the .001" increments you really don't have more than a .001" resolution. On a standard .4525 throat your minus .452 (.4518 actual) with go and you .453" (4528") should be a "no go" Yes you can tell if you have a little or a lot of play on the pin but back to my point a mic. and a small hole gage set will work for the average user.

I agree with just buying a set.

However, if you're needing a few odd sizes, I've used these with no complaints. As said go with minus, that will fit what its marked for. The plus will not.

I have bought Meyer Gage pin gages before and they are very reasonable, like $3.95 per pin. I bought them for .355 through .360. Their shipping is reasonable too using USPS small bubble envelope. That price is from their 2019 catalogue.
