Here's a lil background, relevant or not is your call:
I currently have a S&W 686-4 with a 4-inch barrel. I bought it at a steal! However, being the ammo snob I am, I dont beleive for a minute there is a true .357mag JHP worth carrying for defense. Its not a matter of being able to handle the recoil of .357mag, I just feel for all its recoil, blast, and the fact that there are no decent JHPs available, that its not for me. However, I am having an F'ing blast shooting, the old 158gr+P LSWCHPs through the 686.
However, I've been told there are a shitload of really nice Mod 64s, that are PD trade-ins that many have never been fired, on the market these days. I have been told I may be able to parlay my 686, which is in fantastic shape, into two of the Mod 64s. They all have 4-inch barrels as far as I know. I am really considering this because of the obvious "two is better than one" argument, not to mention my disdain for the .357mag JHPs (yes even the Federal 125gr JHPs), and because I wouldnt be shy about doing my own custom work to them, that I could have more fun.
Anyways, is the 4-inch 64 full underlug?
How about a prefered dash?
Is the front sight able to be removed in favor of a different front sight?
