Choosing a red-dot sight for a 1911 wad gun

First topic message reminder :

I've got lots of questions, but I'll keep this short.

What are the (dis)advantages of this red dot sight, for use on a 1911 ?

Is it appropriate for a 1911 wad gun?
Is it similar to an Ultradot Matchdot II ?
Any reasons to recommend it, or to avoid it?

I just got the Salyer gun I purchased through this forum (thanks to Dan!!), and he included this sight, as he will be putting his Matchdot II on his new gun.  I assumed I would be ordering a Matchdot II for this gun, but at first glance, the ADCO seems like a reasonable product, at a lot lower cost than the Ultradot products.  I'm assuming the Matchdot II will either be "better", or "more durable", or both.  Any opinions on the ADCO?

For that matter, there are red dot sights for a 1911 from $30 or so, up to many, many hundreds of dollars.  Are any of these noticeably better than the competition, and if so, in what way?  

(I have no interest in "trick" stuff - a small red dot is all I want.  Triangles, or other fancy shapes, would be a waste of money.  The ability to shoot under water would be a similar waste.  To me, the lighter weight the sight is, the better. )


One other question - if the choice came down to an Matchdot II or an Ultradot L/T, would one be preferable to the other?  The Ultradot is certainly a lot lighter - not sure if it's as durable on a 1911.

Yea, the 222 is the purple (was too lazy to look up the numbers before).  I've used that also for laptop screws and sight screws.  It is good.  I buy the 290 (green), 242 (blue), and 271 (red) down the street at the local auto parts store.  The purple I've needed to order from McMaster-Carr, Ebay, or Amazon.  Clear fingernail polish (although, any other color would work) is also a decent thread locker for small, fine threads - but 222 is better IMO.  I've also used 222 for grip screws.

222 purple for any small screws. if you use 262 or blue on a 4-40 you're gonna need heat and a prayer



if you tighten a  ring screw with the short end of an allen wrench and it comes loose... you need to check your mount.. base mounts require more.

I used that method on very high recoiling rifle scopes for years before getting a certified hand torque wrench..

To clarify, a short hex wrench versus a long hex wrench is what I meant along with applying finger pressure to the long side of  to tighten the screw.  They make different length hex wrenches, short and long.  Actually, they make a lot of socket head hex cap screw tools, some with t-handles, some that are hex bits (or driver bits), some that have a 1/4" square drive socket on one end or a 3/8" square drive socket.  They probably make more.  But, what I'm referring to is the short style hex wrench, that is typically supplied with a mount - tighten with the long side.  Considering a short hex wrench, long side, is ~2" - 'single finger' tight is about 10-15 in-lbs.
