RMR Glock first impressions

I recently had a Trijicon RMR mounted on a Glock 19c.  A full review will be posted later, so here are a few first impressions.

 

It will take some practice to get used to having an optic on a pistol.  If I bring the Glock up looking for the red dot I don’t see it.  If I bring it up looking for the sights, the dot is quickly visable.

The dot shows any errors in your trigger pull while your pulling the trigger.  This will make this setup an excellent practice gun, and might make it a good trainer pistol when teaching people how to shoot.

The Glock with RMR will still fit in some holsters with out modification.

I do not like having threaded holes in my Glock slide.  I think I would prefer is some sort of helicoil or similar insert was used to prevent possible damage to the threads in the slide.  Also one of the holes extends into the channel that the extractor spring/plunger runs though.

 

Having a red dot on a pistol is interesting, and I will be posting more about it after I get more trigger time with this setup.

Nightforce has a new website.

NightForce optics has a new web site.  NightForce scopes have been popular in both the tactical and benchrest competition crowd due to their durability and accurate tracking.  I own a NXS 2.5-10×24 and love it.

Now there are tutorial videos on how to set the NF zerostops.  This is an excellent addition because the previous printed instructions of how to set the zero stop on the compact models was not clear.

On ported Glocks

Every so often people ask about the ported Glocks.  As an owner of a Glock 19c, a ported 9mm compact, I can answer those question.

Q:  Does the porting reduce recoil?

A:  Yes, by a small amount.

Q:  Will the porting make the firearm louder?

A:  Yes, it is very noticeable firing indoors.

Q:  Does the ported 9mm Glocks shoot jets of flame from the ports?

A:  Only if you use really poor quality ammunition with no flash suppressant.  Even then, the blast from the muzzle will far surpass the blast from the porting.

Q:  Are there problems from shooting in a retention position with a ported Glock.

A:  Not if you cant the pistol slightly away from you.

Q:  Will carbon build up on the front of my front night sight?

A:  Yes, but not enough to prevent its use.(Under normal firing conditions)

Q:  Will the carbon buildup on the barrel and slide be hard to clean?

A:  No harder or longer then cleaning a standard Glock.

Q:  Is it worth getting a ported 9mm.

A:  No, however other calibers might benefit more from porting.

Notes on the FN SCAR rear sight

There is some confusion to the FN SCAR rear sight.  Hopefully this will help clear things up.

The windage is 1 MOA clicks.  There are 36 clicks of adjustment for windage, so 18 from one end will put you in the middle.

Elevation adjust is 1.5 MOA per click.  There should be enough adjustment to go below the 200m mark and have a 100m zero, and plenty of adjustment past the 600m mark.

Ideally the rifle should be zeroed with the front sight, and the rear sight left mechanically zeroed and only adjusted for wind or distance.

M855A1

Guns and Ammo posted an interesting article on the Army’s new M855A1 “green” ammo.  This confirms prior rumors of it being high pressure and inaccurate.  However there is no mention regarding the rumors that M855A1 fouls more then M855.

Sadly, it sounds like there is little good to say about the new M855A1 round.

Home gunsmithing

It is said that people who own Harley Davidson tend to think ownership means qualified to work on them.

Same thing for gun owners.  Not I am not saying that you can’t work on your own guns, but you really need to know what you are doing.

All the time at the range I see failures in AR15s from not installing the stock correctly, fire control group springs in the wrong places.  Firearms unable to be zeroed due to improper sights and sight installation.  1911 and revolver triggers get tuned to the point of unreliability.

I have to be honest, I have done this my self.  Had the buffer retaining detent pop up and cause the hammer to not hit the firing pin.  Had a connector sold to me as “glock brand” cause reliability issues.  Broken screws and bolts using improper torque values.  The list goes on.

Many modern firearms are simple to work on.  However simple to work on does not equal fool proof.  Make sure you know what you are doing when you work on your firearms, and if you are not sure, get an experts help.
