Jennings Machine Sight Pusher and TruGlo GLOCK Sights

TruGlo Sights

Jennings Machine and Tool Xtream Sight Pusher

This one is a twofer. Let’s start with the basic dilemma. GLOCK sights are like the plastic forends on AR-15s. They work. They even work well. But the more you know about how you like to run your gun, the more you want to change out forends and sights. Enter the GLOCK 42. This dynamic little pugilist punches above his weight. And the stock sights are sufficient, but not magnificent. Time for a change.


I’m not a fan of the GLOCK rear sight. It works, but there are better options.


The slanted pin in the Xtream catches the angle of the sight.

I like gunsmithing gadgets. Not that you have to be a smith to use a sight pusher, but you know what I mean. Armorer’s tools may be a better description. Gadgets. I like me some gadgets. So when I found Jennings Machine and Tool, I was instantly smitten. You never know when some sights are going to need to be pushed around.


The flat angle pin works, too, as there are small indentions on the sights where it can seat, which allows the pressure to be applied evenly.


The pin pushes the sight off.

The Jennings Sight Pusher is quite the contraption. The basic premise is based on stability and direct, focused application of consistent force. The aluminum blocks stabilize the frame, holding it immobile, while the turning of the screw applies pressure to the sight itself, and not the frame.


The clamp is aluminum, and simple padding in the jaws keeps the slide from being marred.


Once the initial bond breaks, the sight can be pushed out by hand.

For the purpose of moving sights, the Xtream Sight Pusher is about as substantial as you would need. It works well on GLOCKs, 1911s, and anything that has flat sides. For guns with safety levers, Jennings makes the MK IV, which has cut outs for safeties. I’ve used the Xtream on two GLOCKs, and a 1911, and can’t envision a sight that this couldn’t move.


All you need is a simple tool kit to move almost any pistol sights.


Jennings Machine and Tool. Made in the USA.

The price on the Xtream is $65. The MK IV is $80. This is clearly a one time expense, as the pusher will stay in your tool kit forever. Or you can spend just as much, or more, on a pusher that is made just for one specific gun. GLOCK aficionados know what I mean. Getting a sight pusher made exclusively for a GLOCK is fine, if you won’t ever own anything else. If you might, why not opt for something more versatile?

Why would you want to change the sights?

GLOCK sights work. They are not the most functional, though. As one who trains one handed, I like to see sights that have a functional shelf on the front side that can catch on a holster or boot heel. And GLOCK sights are rather bland. I personally prefer something brighter, too. As I consider GLOCKS to be defensive pistols, I rarely align sights at full extension. Instead, I point shoot or shoot quickly, only glimpsing the sights. In those situations anything that helps you reference the target is beneficial–and color helps. Bright color is even better. Glowing bright color is really helpful in low light.


TruGlo has built a brand on bright sights.


Green or yellow? Green front with yellow rear? Your choice.

TruGlo makes some nice sights. These Tritium Fiber Optics (TFO) have an odd feature that I like a lot. They’re Tritium inside fiber optic sleeves. The dots glow well enough on their own in daylight and low light, but come alive at night. They are also more robust. As you’ll see in the images, the GLOCK sight isn’t robust. These TruGlo Brite Sites are. They’re steel. Dovetailed. The fit was perfect. And the performance was spot on. I installed them in the most basic way I know how, which is to simply center them on the slide. Again, the exacting pressure applied by the Jennings pusher came in very handy, as I didn’t have to hammer anything.


Sliding the new sight back in is easier than removing the old one.


It is a simple matter of moving the push pin to the other side.

The GLOCK 42 sights sell for $153. That’s not cheap, but you don’t get this level of performance and versatility in a lot of the competition. These sights are stout. They stand up to the abuse of holstering in Kydex, and the rough manipulation of training. I’ve had these on this gun (which is what I’m carrying and training with now) for three solid months. No movement. No signs of wear.


The pins fit into this bolt, which is turned with a large Allen wrench.


TruGlo left–GLOCK Sight right.


The TG is a substantial sight, capable and solid.


GLOCK front sights screw in from under the slide.


The fiber optic pics up ambient light, while the tritium glows at night.


Even in action, the glow is easily visible.


You never lose sight of the bright green glow.


The TruGlo sights stand up to daily use and hard abuse.


And they work well. This is six shots from 25 yards. The accuracy is fine–it is the shooter that needs a bit more work.

While you can't push a GLOCK front sight, you can push some 1911 front sights.

While you can’t push a GLOCK front sight, you can push some 1911 front sights.

    Purchased and received this sight pusher with the MK IV inserts for Beretta pistols etc and immediately put to work on sight installations and adjustments. This is truly the first, of many past purchased, sight pushers that is well worth every cent paid for it. It has installed and removed every model of weapon that officers have dropped for such work. The MOST difficult of modern day sights to remove have been the Springfield XD or XD-M, or S sight sets!!! These are so, so hard to move, let alone remove, that I have dealt with many that persons have made attempts to do themselves but wind up damaging the firearms with marks, cuts, scrapes, you name it. Then they bring it for installation. This tool has been the first one that moved these sights, once properly set up in the jig, the easiest I have seen or used. Been doing this work for some 40 years and this tool is now the most often used sight pusher in the shop. Excellent product that is well made and priced far lower than others that aren’t even half as good and effective. Great, Great resource to have.

    I too have sent several e-mails trying to find out how to order a mk 4 sight pusher with negative results.

  • DBC December 30, 2014, 6:05 pm

    Same experience, as the others, have had absolutely no response to emails, strange way to deal with potential customers!

  • David December 8, 2014, 11:25 pm

    Can you make a recommendation for an IWB holster for a Glock 42?

    • OMCHamlin February 14, 2016, 8:02 am

      Yes, I recommend you go find a relevant conversation to ask your question. This discussion (in case you have difficulty following along) is about a sight installation tool…

  • Dean November 21, 2014, 11:36 pm

    Sent two emails and have received no response!
    Are they still in business?

    • Dave December 30, 2014, 10:32 am

      Same here. Why bother to advertise if unwilling to answer ??

  • LJ November 21, 2014, 10:08 pm

    No responses to email at all!

    • Linda Jennings December 21, 2014, 12:40 am

      Are you trying to reach Ed Jennings?

  • Russ November 19, 2014, 4:25 am

    Thanks DAVE HIGGINBOTHAM, very useful info. And will save time or money on gunsmithing.

  • Bob November 17, 2014, 11:31 pm

    It’s the best!
    The front sight needs to be well glued.
    Make sure it’s pointed straight ahead while tightening or it’ll move and you will have a twisted front sight glued in place.
    Grind the face of your socket flat so it will engage that very shallow sight retaining nut.
    This sight system lights up like a flashlight. I use contrasting front and rear colors.

  • Richard November 17, 2014, 10:41 pm

    I’m buying one of these, never know when I might want to just play with my sights. 🙂

    What I really like is they have not decided to charge some extravagant amount for this tool. Keeping the price down really helps us ‘poor’ shooters.
