An unusual lubrication problem.

I get the most interesting phone calls! A client who works for a public agency in California contacted me with a problem. As you may know, California has pretty strict ideas about what constitutes a carcinogen. Management in his agency won’t let him use any lubricants that contain “substances known to the state of California […]

Getting your gun engraved.

The lure of a personalized and decorated weapon is centuries old. Embellished swords and knives from the 17th and 18th centuries are well known; before that, soldiers in high standing had their armor decorated. Some of the earliest firearms in existence are lavishly treated, with inlays and fine woods. Today many people desire to have […]

The importance of endshake.

An often misunderstood aspect of revolver construction is the idea of endshake. Endshake is nothing more than the amount of back-and-forth movement (or front-to-back, if you prefer) that the cylinder is allowed to make. Measuring endshake is easy: using a set of feeler gages, the cylinder is pushed forward and the barrel/cylinder gap is measured. […]

“Can you really conceal a revolver?”

Sorry to be late today, but my cable internet connection has been experiencing spotty outages lately. For the money I pay, you’d think they’d give me better uptime than this! GRRRRRR! But I digress… Anyhow, today’s topic once again comes from that fountain of firearms misinformation, the local gun store. A fellow is looking at […]

Triggers are three-dimensional.

It’s surprising how little attention is given to the back of a revolver’s trigger. I recently came across a gun that had been worked on by another gunsmith (more on this in a future blog post), and one aspect of the gun illustrated the limited understanding of revolver shooting by many ‘smiths. The face of […]

Battle of the “J” frames?

The internet forums sporadically ignite with a common debate: what “J” frame is the best? The disagreement seems to center around the fans of the exposed hammer models (who hold out the dream of needing to make a “precise, long range” single action shot) and those of the enclosed hammer Centennial models (who opine that […]

“What revolver should I buy?”

If I had a nickel for every time I’ve been asked that question…! On every forum, in my daily email, and in the phone calls I receive is a common query: “of the revolvers available at a dealer, which one should I buy?” These folks are looking for some guidance beyond the simple choice of caliber […]

A primer about primers.

When doing action work, I ask my clients how they’ll be using the gun. For instance, a competition shooter who handloads their own ammunition can utilize a lighter action than someone who needs the gun to work with a variety of factory ammunition. Why is this? Well, primers are not created equal – the brands […]

What is it with the reloading press fanatics?

Funny thing…the other day, Tamara posted this rant about brand fanaticism over at her blog. The subject popped up again this week in a different context. I’d popped in to a couple of the reloading forums to ask a question about dies (I’m considering new ones.) Reading through some of the past posts on the […]

Are we shooting more than we used to?

People routinely ask about the lifespan of a particular gun, while at the same time suggesting that somehow the guns of yesteryear would last longer under use than today’s offerings. I’m not sure that this is the case. Let’s jump back to, say, 1935 or so. Someone has just bought a new .38 Special revolver […]

A bit of opinion about MIM parts.

Heard about “MIM” parts? MIM is an injection molding process for metal parts, and it has been revolutionizing many industries. In the revolver business, both Smith & Wesson and Taurus have made use of MIM parts. Like any new process, however, there are those who decry the new technology; some gunsmiths spread the misinformation that […]

What does “reliability” really mean?

A recent rifle class in which I assisted brought to mind a topic which is just not understood amongst gun owners: “reliability.” What is “reliable”? You’ll hear all kinds of definitions, all kinds of criteria. My definition is deceptively simple: the next time you pull the trigger, the gun will function perfectly. That means zero, zilch, […]

Let’s talk about triggers.

I had an interesting email recently. The writer said that he’d contacted a number of gunsmiths to inquire about action work. In every case, he said, all he could get out of them was “we can make it lighter.” Occasionally I’ll get an inquiry from the other side of this phenomenon – someone whose only […]

Revolver grips: finger grooves or plain?

Many people ask me where to get finger grooved grips for various guns (often for the Colt Python, but the Ruger GP-100 seems to be a common request as well.) Personally, I usually try to talk them out of that style grip, and I’d like to share my reasoning. First, the grooves rarely fit any […]

Measuring chamber throats – calipers vs pin gages.

There is a huge amount of misinformation regarding revolver accuracy. Folks, assuming that you have a gun in proper repair – timing, lockup, chamber-to-bore alignment – the most important factor in accuracy is the chamber throat dimension. What is the chamber throat? It is the slightly constricted opening in the chamber, just in front of […]

What “generation” is my Colt Detective Special? Depends on who you ask!

Many people talk about the Colt Detective Special using the term “generation.” I get emails asking which “generation” is best or which should be purchased. I recently got a nasty email from a potential client who asked if I could work on a certain “generation”; when I replied that I wasn’t sure what he meant […]

“Can My Colt Use +P Ammunition? “

This is one of the first questions a new Colt “D” frame owner asks. The answer depends on the model and the vintage of the individual gun. What Colt says Post-1972 (shrouded ejector rod) models: The owner’s manual says that these guns are rated for +P ammunition. The manual calls for a factory (gunsmith) inspection […]

Lubrication 101: Gun oil, snake oil, and how to tell the difference.

Important update and disclaimer: This article was originally written in 2006. In it, I made specific recommendations for Lubriplate products, recommendations which have not varied significantly in the decade-and-a-half since publication. At the time it was written I had no affiliation with Lubriplate or their dealers; I was simply a happy customer who found their […]

Is the Colt Python revolver delicate?

There is an assertion that comes up with surprising frequency, particularly in the internet age where everyone is an expert: the Colt Python (and all other Colt revolvers) are “delicate”, “go out of time easily”, or “not as strong/durable as a S&W.” Let’s start with the construction: a Colt revolver, for any given frame size, […]

Which brand of revolver speedloader is the best?

Lots of people ask me about speedloaders – as in “what speedloader should I buy?” Well, there are really only a couple of choices these days: the push-type (typified by Safariland) and the turn-the-knob style (like the common HKS.) There have been others; the superb SL Variant models are no longer imported, the Maxfires don’t […]

What is a “good” trigger?

I recently met a fellow who was shooting a Colt Detective Special. We talked about his gun a while, and I asked him if he’d had any action work done to it. He said he hadn’t; sure enough, on trying his gun, I felt the typical Colt factory trigger – heavy and ugly. Since I […]
