You've got some choices, some of them quite good.
If you're interested in purely velocity at the muzzle, some of the old kinds of chronos work pretty well, as does the Magnetospeed (as long as you don't shoot the bayonet, no matter how 'lightly'). The Magnetospeed does seem to be very accurate...
As of 2022, Bob Marvel used to run a course up at his place in Nebraska, but that was primarily a 'build' rather than general 1911 gunsmithing course.

I haven't used that range and haven't attended one of those events, but here's a page from a shoot last year using the same range:

Activities marked in Yellow are usually open to the public. If you click thru' to the event entry, it'll tell you whether registration is required and will usually have a flyer or additional web link that explains what the rules for attendance are.
I've been a member for a couple years now, and...
I can see a valid reason why I might want other people to carry in Condition 3 - for my safety.
People who carry guns who never practice, have poor trigger discipline and/or insist on carrying with an inappropriate or no holster, just to name a few.
You have to admit, most of you have seen or...
I work from home and have a fat gut. Carrying all the time is a real chore for me. Obviously, that's a bigger risk than carrying appendix OR in Condition 3.
Getting habituated to carrying, and really knowing your manual of arms and training to it are key.
The underlying philosophy of carrying in Condition 3 (Israeli carry, 'none in the pipe') was promoted in print by Fairburn & Sykes in "Shooting to Live", but presumably predates that. And of course it was (and I think still is) observed by the IDF and as noted, a number of other militaries.
If...
Last time I checked - about 8 years ago - I remember it being over $200/year. There are no prices on the site at https://adairsvillesportingrange.com/ but I guess you could phone them.
There's River Bend, but you'd need to become a member - and it's probably only a bit further away than Garland Mountain. I'm not a shotgun guy, but the impression I get is that the facilities are great.
It depends on the kind of shooting you're looking at.
Bill Rogers' place is up in Ellijay has a great reputation. I've not done a course with his firm, but I know a few quite experienced guys who have, reporting back that they thought the course was worth the money.
As your eyes (usually) deteriorate with age, you'll start to find that all other things being equal, a red dot becomes more and more useful.
Anyone can learn to use a red dot, it's all down to familiarity and training, but the amount of training will vary person-to-person. It can be dispiriting...
The problem with prisms in that application is that you don't have much, if any, choice. A prism sight tends to need more light, and comes in a larger package.
Quite feasible for rifles, but less so for pistols.
