A heavy trigger complaint is historically about the double action. Is the problem really the single action pull?

Our local gun shop has a High Standard Sentinel Mark IV with both the .22 LR and the .22 Mag cylinder assemblies. The condition is very good - no marks on the metal except the cylinder turn line and only very minor marks on the wood. Asking price is $649.

I'm interested, but know nothing about these revolvers (although I've owned a High Standard semi-auto pistol since 1969). So, some questions:

1. The single action trigger pull on this revolver is less than optimal. Are they readily adjusted and, if so, how? Is this something you do by swapping out springs or by polishing the sear?

2. Do these pistols hold up well? I'm thinking of it as a training handgun for my grandchildren and I want something robust enough to allow the regular use of it.

3. Are there any things related to function I ought to be looking at carefully before buying the revolver?

4. The serial number was either S70xxx or 570xxx (the first letter/digit was not very clear). When was the revolver manufactured?

5. And, of course, how does the asking price seem?

I'm not a collector, so this will be shot a lot and possibly added to my woods carry rotation. It's not a Colt Diamondback or a Smith Model 14, but it does seem like it might be a good choice for the purposes I have in mind.

So, any thoughts you might have would be greatly appreciated.

Thanks.

1. A heavy trigger complaint is historically about the double action not the single action. Is the problem really the single action pull?

2. These revolvers are durable.

3. Yes, conditionally on which revolver you actually have. Is this a factory two cylinder revolver or one made up by a previous owner?

4, The first character should be the letter "S". Accurately dating and validating the specific model your are asking about requires a complete serial number. Generally speaking the MK IV came with only a single magnum cylinder. However there were a very few MK IV's that were sold with two cylinders even though they were not in any catalog or price list.

Depending on the answeres to my questions in 3 and 4, the price should fall between about right as a collector to pretty high if it is not a factory original and the second cylinder is not correctly timed.

What is the barrel length and does it have a fixed or an adjustable rear sight?

 

From my experience and at that price I would look elsewhere. I would closely examine cylinder timing on both cylinders. Parts are nearly nonexistent.

 

Thank you for that information. The heavy trigger pull was on the single action function. I didn't try it double action.

I'll have to go back to look at it again to get an answer on the cylinder. Are they serial numbered somewhere or would it be a matter of having to take the one off to install the other to see if they are original and properly timed? FWIW, the .22 Long Rifle cylinder was the one mounted; the .22 magnum was in the case next to it.

The gun is marked as a Mark IV.

 

I know this is an old thread but I just happen to be diggin around in the safe and came across these Mark IVs.
I was looking for the satin finished one to take with me to the woods this weekend as I hadn't seen it in years and then came across the blued one that I had all but forgotten about. What a great surprise. I looked up my records and found that I had paid $250 and $170 for them.
Tonight (photo) is the first time they've been introduced.
