I just put one on a 17. I plan to shoot it in a match early next month. So far I like it.

 

I have the Burris Fastfire III on my G41 duty gun and it is accurate and durable.

 

Have one on my FNX-45T and another that was on my FsN, moved to my G40MOS, and then taken off. They work fine once you are used to a red dot. I would suggest the smaller MOA if planning on using it to hunt or shoot at anything over 25yds. Also, once you put it on, the next step will be co-witnessing your irons. The stocks don't, and I bought Ameriglo tall suppressor sights, which aren't high enough to co-witness. I am debating trying the trijicon suppressor sights, a trijicon RMR, to get co-witness, or just stick with the stock sights. If I stick with irons, I'll be looking for steel.

As far as durability and battery life, no issues other then brass beating up the top shroud on the 45T.

Morning,
If I went with the standard G20, would mounting be realistic?

 

Ken,

With the standard (non-mos) you would have to have the slide milled, or use one of the dovetail mounts. There are a couple of newer mounts that use the dovetail and have iron sights as part of the base, but these are not quite prime time, yet.

With a dovetail mount, you will not have the ability to co-witness. This means a steep learning curve to draw and find the dot. The faster you need this to happen (use of the gun) the steeper the learning curve, and the more dependent you will be on your training/presentation with the gun.

Having had red dots on several hunting guns, sans co-witnessing, finding the dot can be a lot slower, but usually not a deal breaker, for hunting. Much like a conventional scope on a hunting handgun. Most folks are not "snap" shooting whitetails. If you had said hogs on the run, I might be more concerned.

Thanks Craig,
I may end up just getting some good adjustable iron sights, as most of my deer shots have been relatively close
Thanks again

 

Ken,

You are very welcome. The dovetail mount is not my first suggestion to most folks, but on a hunting handgun, they are very doable. The plates are not insanely priced, and work well enough to use a sight, and get a good feel for them. Not a bad way to experiment, especially if you could throw the optic on a long gun, if not liked.

I have the Fast Fire III on a S&W 627 Pro .357 revolver. I love the clear, round dot and the ability to shoot with my distance prescription glasses on. I got mine from Amazon for $239 but I think it was an undeclared open box unit, one screw was buggered.

I have a few boxes of specials and magnums through it and it has held up fine. Since it is a revolver and mounted on an adapter in place of the rear sight the dot can be a bit slow to aquire. I just raise the muzzle till I see the front sight, center it and then lower the muzzle till the dot comes into view. Takes longer to type than to do.

Hey Ron,
So does a mount exist that will allow me to keep my iron sights in place, and also mount the Fast Fire for deer season, and than be able to remove it after deer season?
Thanks for your help

I guess I don't understand. You have a G40 MOS, right? So you have 4 adapter plates for the various red dot sights and a cover plate that came on your gun. For some reason Glock didn't list the Burris sight but the plate that fits the JPoint and Docter sights also fits the FFIII so you can mount it, fill the freezer and then remove it and replace the filler plate.

You will need to sight it in again of course after you remove and remount it, but that is just a trip to the range to go shooting, win/win.

If I'm misunderstanding, let me know and I'll try to help. The only mount I know of for a red dot that offers real put it on, take it off, put it back on with no sighting is the Atom mount. If I had won the powerball I'd have one and could tell you how I liked it. Sadly, I did not.

 

Hi Ron, no, this is for the standard G20

 

Sorry, must have missed that. In that case I can't think of anything affordable other than a frame mount. Which for a hunting gun might be your best bet.

Puts the cost up though added to the sight.

 

Besides price, the frame mounts may require the removal of both front and rear sight for the gun's slide to function, or be removed. The frame mounts tend to be used more on dedicated race/competition guns. They are also a pain in the neck to try take to the field in anything other than a zippered case.

Well, if you look for a silver lining, for the price of a Fast Fire III and a mount, you can buy one heck of a nice set of adjustable iron sights.
