Burris FastFire II and the FNP-45T

Post by Buffman » 15 Feb 2011, 11:12

Finally got myself a Burris FastFire II for my FNP-45 Tactical. This is my first MRDS, and have a question on how to install it on the FNP-45 Tactical. Forgive me if any of the questions have already been answered, I could not find them.

First we have the plate the optic mounts to from FNH. Do the longer pins side go into the slide, or the shorter ones?:

Image

Next, it says I need to mount the gasket plate under the sight for waterproofing/resistance. I Assume this to be that gasket plate:

Image

IF so, then the kit also includes a thicker firmer "gasket plate", which to me is more like a shim. IS it a MOA shim (for elevation adjustments), or is it the "gasket" plate?

Image

Finally, do any of your guy's BFFII, have burrs on the bottom holes for the locating pins? It appears three of mine do:

I truly wish I could assist, however, I have a Trijicon RMR on mine and the installation was very simple. I did look back at my owner's manual and the installation of the FF2 is not listed but I bet you already knew that.

Same here, I'd take my FF2 of the AR15 and try it, but my RMR is loctited on the FNP-45T...

I'm mainly curious which one of those is the "gasket" plate. Whether the thin actual gasket, or the thicker shim. If the later, then the tall pins have to go into the sight, and short pins into the slide.

I would put down the rubber/plastic part first, then the metal shim part, then the sight. It would make sense that the first rubber part creates a seal under the shim part, and that the metal shim is there to fill the void cutout in the slide properly, something that the sight may or may not do, based on its dimensions...

So your assesment that the tall pins have to go into the sight, and short pins into the slide is more than likely correct...

I used the thinner "flexible" gasket on the ones I mounted and never had any issues

I'm half wondering if the thicker shim is a MOA shim.

Burris FF and FFII are poor choices for the FN 45 Tactical. As most probably know, the windage and elevation adjustments screws aren't locking themselves. The rear of the sight contains locking screws for both adjustments. Sadly, the FN rear sight sits flush against the FF when it's installed so there's no way to lock or unlock the sight adjusment screws without removing it from the pistol, unless you'r planning to remove the iron sight. For this reason alone the RMRs are a much better choice even if you figure out how to mount the FF.

The original doctor sight is the same way, and I have no concerns. I may not even like a red dot on it, and didn't want to spend the $450+ on a RMR.

I had a Burris Fastfire II on my HK P7. IMO the window is too small for "tactical" use on a handgun, as it is very easy to misalign the pistol in high stress low light shooting situations, however, as a range tool.....Seriously badass.

With my P7 i can drive 1 hole 10yd doubletaps one after another after another when the FF2 is mounted.

I do not agree with your opinions, but would like to say the P7 is a very nice pistol, and yours is even more so. :)
Never attribute to malice that which can be explained by stupidity.
The shooter will always matter more than the gear ever will.
Stop relying on others to do the work for you.
Shoot more, worry less.

Drawing from a holster in a good shooting stance it is quite easy to pick up the FFII.

However (for me at least), laying in bed at night (or on your back, or in some other awkward position), pistol on nightstand in a pitch black room, that little window is almost impossible to acquire if you have to suddenly grab at your pistol and engage a target, as you would have to do if someone burst into your room during a burglary or home invasion at night.

I made a modification to the Burris hudframe window that helped immensely though...

Image

If you are willing to dedicate a lot of time practicing with the pistol so that the alignment is automatic due to ingrained muscle memory, it would probably be a lot more viable, but to me, it is a very training intensive device. For low light, awkward position shooting, i really favor a good quality laser system.

Here's a pic of my modified P7 as it sits today:

Thanks for the compliments. :)

Wood grips on a P7 are my new fetish.

Me and blue were just talking about them last night.

I love them too, they really transform the gun from an ugly duckling to a beauty queen.

Here are a few more pix of my Nill wood gripped P7. I'll toss in some with the Fastfire mounted to keep it on topic. ;)
