Precision Pistol Perspective with all the bias that entails, with the exception of Mr. Clapp. Understood Bullseye aka "Precision Pistol" may not be the OP's game of choice so there is that
I guess if I always shot my pistols from machines I’d treat them more like my benchrest rifles and only shoot them from machines but that’s not how I use my 1911’s and most other pistols.

Clapp on Handguns: Ransom Rest Revisited by Wiley Clapp - American Rifleman
"Further, I have people stating that the results obtained do not show what a handgun will do when fired in a human hand. That's the good part. Human hands are part of humans, which are at least inconsistent and sometimes downright erratic. Marksmanship enters into hand-held shooting, even on sandbags. If your trigger release and follow-through are not perfect, your groups on target won't be truly representative of what the gun and ammunition will do. It should be obvious that results will differ with different shooters. That's why shooting by hand (when a Ransom Rest is available) doesn't make sense. The major advantage of the Ransom Rest is consistency—it holds the pistol in the same way every shot. It will shoot the same way for hours on end and with thousands of rounds down range. I know this for a fact, because I have gone from dawn to dusk in several different shooting sessions. For a shooter, particularly a handloading one, the Ransom Rest provides the ability to maintain quality control over large batches of a given load. It's also handy in developing a new load or selecting a commercial load. Several 10 shot groups with a commercial or handmade load through the same gun will pretty much show what your gun will do. If you have a gun of known accuracy, careful use of the Ransom Rest can show you what each of many loads are capable of. Wiley Clapp"

The Custom-Built Handgun - by Larry Leutenegger
"...I function-fire the gun, a minimum of 50 Bullseye rounds. I function-fire by hand, so the gun has the same resistance and movement as it would in a match. Finally, I accuracy-test it in a Ransom Rest, with several kinds of ammo, including factory match (using lots I know are accurate) and my best handloads. Larry Leutenegger"
If you just want to know what the barrel is capable of just get the pistol out or the equation and use a fixture like the one used here, start around 1:19.
Testing barrels prior to installation is valuable, to ensure they meet accuracy requirements. However that may not help someone with a completed build, other than to recognize a poor performing barrel. A fixture also won't validate proper installation/fit on its own. That is where a mechanical rest comes into play, and you'll still need one even with the fixture.

Next item is cost. The only pistol barrel fixture in production I'm aware of is by Dave Sams and the cost is about $2800+ inserts unless you constrain it to one platform like the 1911. Probably outside the OP's budget since you’ll need a mechanical rest regardless.

A Day With A Master Gunsmith by Chip Lohman - Shooting Sports USA
“It starts with the barrel. No amount of welding up or machining is going to improve an average barrel. That’s why the first thing I do for a new build is to shoot just the barrel from my barrel test fixture. If it turns out to be an average barrel, I put it aside for “pie plate” shooters. Once I know I have an accurate barrel, I move onto building the rest of the gun, which involves fitting the bushing to the barrel, then fitting the bushing to the slide, and on to the other work depending on the model gun I am building. For the ultimate in match preparation, you can send your firearm to a gunsmith for accuracy testing on a mechanical rest.” - David Sams

In a loose fit, the barrel becomes a camming device which positions or attempts to position the upper unit. The weak link in the 1911 accuracy equation, is the dynamics of the barrel. A barrel tester will show the capability of a barrel. The amount of loss when installed in the gun will show the skill and ability of the builder. The better the frame/slide fit, the closer to a stationary barrel.
I have spent almost 40 years, shooting/testing on the RR. One thing has become apparent during that time. Build as robust platform as possible. I have graduated to 2+ yards of concrete, covering approx. 1000 pounds of I beams, and steel channel reinforced/supports all welded together. The base mounting suggestions of one inch wood for the RR are meager, and with the slats on each end, flexes in the middle. It really needs 4 inches of steel reinforced, laminated 3/4 in plywood glued and sheet rock screwed together. The RR base uses wood screws to attach to the wood. Poor at best.. Machine the mounting holes to accept countersunk bolts that pass thru the wood. 1/4 inch steel plates inlaid into the wood base on both sides aid in supporting and anchoring the base to the wood. Many will say "overkill" but the guys at the top test frequently. You must know how your equipment is performing. Ammo, powder, barrels, lot to lot is almost always different. A gunsmith cannot afford to build guns that are not shooting micro groups. The shooters at the top are going to test your product. It better be right. I wish, I had the money and time I have wasted, rebuilding guns I "thought" were not up to that standard, because of an inadequate test rest platform. Because this super heavy RR is so very reliable. The old "settling shots" phase of the test is gone. It shoots good groups from start to finish. Dave Sams has an HEG rest. I feel as Dave does that it is far superior to the RR.
The reason most of us "elitists" entered this foray, is because Steelwolf made the broad, sweeping, declaration, that slide to frame fit had zero affect on accuracy, period. He did not segregate disciplines. We "elitists" pointed out that in extreme accuracy applications, it in fact does. There is a small clientele base in this country that can shoot at 50 yards, to the potential of the gun, and those shooters request and seek out the best we are able to produce. Plus, they realize, that humans error and fatigue. Very accurate guns, mitigate those errors. Your past employer who put slide to frame dead last. Well, thats odd, because it is the very first step usually taken by an "elitist". For, the frame and slide is the foundation for the entire system. The Ransom Rest is not a crutch. It is a tool, one step below the barrel tester, to test parts, the final outcome, or to test various machining techniques.

There isn't a high master out there who will shoot a pistol that isn't shooting at the highest level of accuracy. But typically proven in a ransom rest; yes I know that's different than from the hand.
