We baby boomers had parents who were raised during the depths of the depression, fought in World War Two and deservedly earned the title of The Greatest Generation. By comparison to them, we boomers had it easy. One notable advantage that we had over our parents was easy access during our impressionable years to the finest gun writers in the history of sporting journalism.
Ask any “boomer” gun nut who their favorite gun writers were when they were growing up and the list will certainly contain Elmer Keith, Bill Jordan and Skeeter Skelton, revolver devotees, all. Those scribes led some of us down the road from mere interest to obsession, to near-fixation with guns and shooting at an early age.
Until the late 1970’s and the rapid growth of IPSC, revolvers dominated the handgun culture here in the United States, and most of us boomers cut our teeth shooting revolvers. As the sport of practical shooting mushroomed, semi-autos in general and the 1911 specifically, started to make inroads into the popularity of revolvers. Add to that the importation of high quality, functional and innovative semi-automatic handguns from Europe, and a major shift in handgun enthusiasm commenced.
In 1986 the GLOCK 17 hit our shores followed in 1988 by the GLOCK 19. Up until that time, police departments that didn’t issue revolvers were as scarce as a Kardashian at a tractor-pull. Now, the opposite is true. While the revolver collector market continued to thrive, the market for new double action revolvers declined.
I can’t explain exactly when or why it happened, but wheel guns are in the midst of a rebirth of popularity. My friend Ken Hackathorn has said that we’re experiencing a “revolver renaissance,” and I agree. In 2017, Colt reintroduced the Colt Cobra, followed in 2019 by the King Cobra, the Python in 2020, the Anaconda in 2021 and the .22 King Cobra in 2022. Whether their reintroduction of these models is the cause or effect of the renewed enthusiasm for revolvers, I don’t know, but I am grateful for the reinvigoration.
A couple of months ago, I was shooting with my friend Matt Olivier and he mentioned that he had attended a media event at Gunsite where a unique revolver was debuted by Finks Custom Gunsmithing. Dave Fink and his cadre of gunsmiths serve as the on-site gunsmithy for the school, repairing students’ guns as well as building some of the finest custom firearms available. The revolver that was being displayed had interchangeable barrels with a unique method of alteration.
Swapping barrels on revolvers isn’t a new concept. In the 70’s and 80’s, it wasn’t uncommon to see pistol smiths like Bill Davis and Reeves Jungkind fit Colt Python barrels onto S&W or Ruger actions. The resultant “Smolts/Smythons” and “Cougars” were primarily PPC guns as competitors felt that the faster 1:14 twist of the Python’s barrels shot tighter groups than the slower 1:18 ¾ twist of the Smith and Ruger barrels.
Dan Wesson brought do-it-yourself barrel swapping to the handgun market in 1970 which coincided with the rapid growth of metallic silhouette shooting. With practice, a competitor could, within a minute, swap barrel lengths of 2½” to 15” on their handgun. Dan Wesson no longer manufactures revolvers which has left a void in the marketplace for those who value the concept of altering their own handgun.
The MIBS modification is more easily observed than described. There’s a rectangular button that sticks up on the front end of the top strap of the action. This button is spring-loaded and is attached to a short rod that sticks out in the front of the action and fits into a spherical cavity that is cut into the back of the barrel rib, locking the barrel in place.
When pulled to the rear, the button pulls the rod out of the cavity allowing the barrel to be manually unscrewed and removed from the frame. Conversely, attaching a barrel is a matter of manually screwing on the new barrel while holding the button to the rear. When a barrel is fully screwed in, release the button and the spring-loaded rod goes forward, fitting into the cavity in the back of the barrel rib, preventing it from turning and locking it in place.
Adjustable sights sit high enough on the top strap that the button isn’t visible in the sight picture. While simple in concept, timing the lockup of the barrel requires precision craftsmanship to accomplish it. These guns are fitted, not assembled.
When building a MIBS gun, the individual barrels that the customer selects are mounted on the frame and a barrel-cylinder gap of four to six thousandths is set depending on the ammunition that the customer is using. They then recut the forcing cone, crown each barrel, and set the timing of the barrel fit for lockup. That ensures that each barrel/action combination has been accurized. Finks then installs the front sight that the customer wants and does an action job and zeros each barrel.
Their action job involves polishing the internals and replacing the mainspring and rebound slide spring with an objective of having an 8-pound double action trigger pull without stacking. Test targets are fired to insure both accuracy and that each individual barrel shoots to the same point of impact. The guns are tested from a Ransom Rest at 15 yards. According to Dave, they have yet to have one shoot over ¾” groups and most are ½” or less.
For revolvers with short ejector rods, an additional detent-lock is put on the yoke which locks into the bottom of the barrel. This is necessary since the rod is too short to lock into the forward locking bolt on longer barrels.
The gun that I tested was a Smith & Wesson 686-6 Plus that left the factory with a 2½” barrel and now has an additional 4” barrel. The double action trigger pull on this gun drops the hammer an ounce over 8 pounds without any noticeable stacking.
While my trifocal bespectacled eyes impede my ability to shoot Ransom Rest-worthy groups, my results were above average for me. Of note, shooting consecutive groups with both barrels showed no shift in point of impact which was an initial concern of mine.
A secondary concern I had was durability. Specifically, I questioned whether the system might shoot loose, especially with a steady diet of +P ammunition. Dave said their initial beta testing involved an independent party shooting 1000 rounds utilizing multiple barrels. The test gun held its initial accuracy and the barrel-cylinder gap didn’t change from its original setting. Based upon that trial they were satisfied with both the quality and durability of the system and geared up to produce custom ordered guns.
Dave built guns for two customers who live in Alaska, one in .44 Magnum and one .454 Casull. They each ordered a long barrel to be carried in a chest rig for field work with an additional 2½” barrel they could put on the gun and stick in their waistband when they go into town. To date there have been no issues.
The basic MIBS modification runs $395. Extra barrels are procured from various sources such as J&G Sales, Numrich Gun Parts, Apex Gun Parts, Jack First Gun Parts and even eBay so prices vary due to availability. The alteration is currently available for K, L and N frame Smiths.
When considering the options of multiple barrel lengths either ported or non-ported and numerous front sight configurations, the combinations are as profuse as preferred gender pronouns at a college campus protest. They may not qualify as “bespoke,” but they’re as close as you can come to it in the handgun arena.

I’m diggin’ it!
Sign me up for an N-Frame .45 ACP with 3″ and 5″ barrels.
This might prove very interesting…
