Micro Red Dot on 642

[Cooperd0g]

I have searched all over and am not sure if this is possible. Say you wanted to mount one of the newer micro red dots like the Holosun 407/507K or Trijicon RMRc on a fixed sight J Frame like a 442/642. How could you do this?

I know there are mounts from companies like EGW for the standard S&W adjustable sights. Can you drill and tap that pattern into a J Frame? Or can a standard dovetail be milled in?

Not sure why you would need a dot on a channel sight j frame. Defeats the purpose of the small size and I would argue that the channel sight is faster than any red dot. Either of those sights adds significant bulk. To each his own I guess, just my 0.02 plus the fact that you'll need to d&t your frame (yuck).

If you must, you can buy a mount from allchin gun parts. As stated, the top will need to be d&t S&W J frame - AllchinGunParts.com

It is more a thought exercise than a plan. A Holosun 507K only weights one ounce so it isn't a significant weight increase. And depending on how one carries it there is no difference than putting a red dot on a small semi auto.

But it sounds like something would have to be drilled or milled to do it.

I do not believe that can be done in a graceful way

The alloy frame's screw holes would be subjected to considerable recoil stress from the holographic sight

I would think that an attachment solid enough would be bigger and moe obtrusive that we would want

I totally agree with GaryHK in that a red dot on a "belly gun" is a bit unnecessary and IMO and somewhat detrimental. It's an up close and personal last ditch close quarters belly gun - not a 25 yard target gun! Adding a red dot to a gun typically used at 3 - 5 feet, why would you need it? If you can't hit a human sized target at that distance I don't think you should be using that gun in the first place - just my opinion.

It also adds weight, bulk, and requires a special holster. For a 2" J-Frame practice sessions should be kept to realistic distances of 3 - 12 feet - again, IMO.

And......... IMHO a red dot could actually cost you your life! Here's why! If you train your brain to always look for the red dot then you will automatically be looking for it if that moment ever comes. If it takes you an extra second or two to pick it up, if it malfunctions you will still be looking for it, if you forget to switch it on it won't be there and you just might be too slow to react in time. For SD - KEEP IT SIMPLE!

Due to aging eyes, I've experimented with RDS's. The increase in bulk is an issue for concealment on a full size service pistol. Holster availability hasn't really caught up beyond "meets IDPA requirements" competition gear, which means wearing a circus tent or wink, wink, nudge, nudge "concealment". On a 642??????????????? fuggetabout it!. You'd be almost doubling the bulk of the gun.

Finally, while optical sights have proven faster/more accurate with shoulder fired firearms, handguns lack the stock to give instant eye/sight alignment on the rather narrow window of RDS dot visibility. Yes, you can get there with a lot of practice, but-with no BUIS capability- if you don't see the dot immediately, you're essentially screwed.

Yes, at 15-20 plus yards they're much better than irons. However, the average armed encounter distance for private citizens is in the 5 yard area.

Yes, the military adopted them, but, I rather expect those are all going to Spec-Ops folks. They're not concerned with concealment, have an entirely different mission and most of us don't have night vision gear. Really great tool for offensive operations.

That is what I was concerned about, thank you.
