I have a nice P&R Hwy Patrolman that I want to love. The two problems are the coke bottle grips and the 1/2" wide serrated trigger. I have big hands but this still doesn't fit me.
So. best ideas for more ergonomic WOOD square butt stocks and a replacement trigger. I may just take a mill and sander to the stock trigger if it seems easier.
OK.....the HP never originally came with coke bottle grips AND those are quite valuable. I suggest you take them off and protect them. A nice pair will bring $300 without much effort to a S&W guy.
The problem that I'm seeing is that perhaps the gun being in target configuration doesn't fit your hands. The HP was a SERVICE arm, that had adjustable sights. ORIGINALLY (unless there was a special order), the model 28 aka Highway patrolman had a standard hammer, standard aka service trigger and service grips (which show the frame all the way around)
If I'm getting your post backwards aka the grips and or gun are too small for your hand, then I suggest you get some custom grips ordered. If you want the standard size trigger, find one that will fit your gun. IIRC the L frame and K frame triggers are the same as the N or at least very close. If you want the trigger wider, when you say you have a target trigger now, I'm not sure what you should do.
I'm a little confused by your post. Anyways...
First is a pic that shows what a real coke bottle aka CBG S&W grip looks like. Many people are confused over what constitutes a coke and for what models they were placed on. The coke is on the right with its immediate successor on the left.
Also, there are some pics of the differences between a model 27 and 28. Both of these are -2 guns from my collection. The nickel gun is my 6 in 27-2, and the blued gun is my 4 in model 28-2. Both are stock aka original and in exceptional condition.
First, the CBG vs the later N frame diamond targets (which later had the diamond removed, like on my model 27 - the most common type):
Here is a nice pair of CBGs. Note the larger checking pattern compared to later grips WITH the diamond around the screw escutcheon.
Notice the wider trigger, target grips and wider hammer which were standard on the model 27 but optional on the 28. Often times a model 28 with target parts has parts which were later added by an owner for various reasons. Also the model 28 has the original N frame service grips vs the target grips of the 27. Target grips were more common for the N Frame with magnas only being on 27s by order, or model 58s. Most other N frame models you see of this vintage have target grips consistently.
Another shot of the triggers:
The hammer difference:
And lastly we have the famous checkered top strap vs the non checkered plain stop strap of the model 28 aka highway patrolman.
