One Source Tactical - Technical Services Division has been installing TSD packages on Glocks for quite a while. Our technicians have done what many though could not be done. Recently our staff was able to install the system on other popular pistol systems. In order to answer your questions, we have prepared an FAQ with regards to these TSD packages.
LED vs. Dual Illumination – The dual illumination is only available from Trijicon. On which one is better, well that depends on where you will be using the sights. I have a colleague that is in Africa and his battery availability is slim so he opted for the Dual Illumination RMR Unit. Here in the USA, where you can buy batteries everywhere, I prefer the battery powered LED version. I find it is more consistent across varying light levels, and the battery life is about one year.
The importance of the suppressor sights
– The suppressor sights do two things. One is they shorten the learning/training curve dramatically. Why?
Because your eyes are accustomed to looking for the iron sights from years of dry and live work. Thus the eyes will pick up the suppressor sights immediately and coincidentally the red dot as well. We have seen this in our classes. Students running just the red dot require a greater learning curve opposed to those running red dots in conjunction with suppressor sights. Additionally, since anything man-made can fail, the suppressor sight provide a true co-witnessed backup system in the event the red dot fails.
What size dot do you recommend -
This is always a compromise. We played with the smaller sized dots and while they were fine on rifles, what seemed to work best with the handguns was 7 MOA or larger. The reason for this is on a rifle, you have two additional points of contact (shoulder and cheek) facilitating the visual identification of the dot. On a handgun, you do not have that so a larger and easier to pick up dot works better for most people. A 7 MOA dot translates as a 7 inch group on target at 100 yards.
Maintenance and care –
Virtually nothing. I carried one of our TSD Glocks in the field during inclement weather and while the unit got dusty and dirty, it worked fine. Maintenance is no different than you would use on the Aimpoint on your AR-15 or AK.
Commonly used holsters or way to carry – As long as your holster is cut down in front, as most tactical holsters are, your red dot equipped gun will fit. We can point you to specific holsters for the red dot equipped holsters as well.
How durable – Well that depends on the unit chosen of course. On my personal guns I am running Trijicon RMR red dots. These are designed to be mounted on an M4 and dropped from shoulder height (onto the RMR) and retain zero. They are more than tough enough for mere pistol usage. While we will happily install Insights, Burris, J-Points, or Delta Points, these other sights may not be as robust as the Trijicon .
How long batteries last – Most of the red dot sights on the market today have similar battery life, and that is roughly for one year on constant “ON”.
Why choose this over standard sights
Standard sights are fine for many defensive problems, but as the shooter gets older, they are not as easy to use. What many guys try to do then is install oversized sights, but then the problem is they cannot be indexed on target well.
The red dot system does for the handgun what it has been doing for the rifle for many years. It eliminates the need to keep rear sight, front sight, and target aligned, and the visual gymnastics that requires.
As well the red dot allows you to index an very visible aiming point on any target you wish to hit under any lighting conditions from close range to as far as you can hold.
The advantages and disadvantages of Front / Rear BUIS location – My personal preference is to install the BUIS (back up iron sights) in the traditional locations on the pistol slide. The benefits to this are that the training/learning curve is considerably shortened. Now, as far as for our technicians, it is considerably harder work to install the system that way. The reason we do it that way is because it is a better system, easier to transfer over operationally from non-red dot sighted handguns and back. The reason that the alternate installation (rear sight in front of the red dot sight) was invented was simply and purely to facilitate the job of the gunsmith. Being capitalists, we will install the red dot sights anywhere you wish, and thus offer different packages, but the one you will see in the holsters of our staff is the BUIS in the traditional position.
How to get one installed (what do I send, where do I send it, etc). – That is easy. Some guns will require you sending us the slide (slide only please), other guns we will also have aftermarket slides already set up for the red dot system. As well, various color finishes are available on the slides.
Turnaround times – Quicker than anyone else in the industry.
How much Real Estate is needed to mount one – That depends on the red dot unit you want to install. Thus far we can do Springfield XD, Smith & Wesson M&P, FN handguns, Glocks of all sizes, 1911s, and we are working on the HK and SIG systems.
Any required changes to normal handgun operations – Not at all.
Why the RMR was selected over other available Red Dot sights
Again, I want to mention that we will install any red dot sight you would like on your pistol. But my preference based on research and testing is the Trijicon RMR.
This is the best system available today, in my opinion, for a handgun and what I have in my holster.
For clarity I will post why I deselected some of the other sights for my personal use –
J-Point: They are polymer construction. They give a good clear dot and have a battery life of about two years. One issue is “waterproofness” . I was told that a little rain will not hurt the unit by the reps at the J-Point booth. Not very encouraging. The notch in the back is thought to be a back up sight. It is not and any coincidence between dot and irons is pure happenstance. Finally, it is now only available in 4 MOA. This may be easier to install on slides that have less real estate however. The glass is not as clear nor is it as strong as the RMR in my opinion and experience.
Leupold DeltaPoint: In my opinion, overly complicated. There is a 7.0 MOA triangle whose edges seemed indistinct to me, or a too-small 3.5 MOA dot. It has a wide easy to see through screen. And the small “footprint” might make it an easier marriage to a narrow slide. The adjustments on the stern side of the unit make a traditional BUIS installation more complicated.
Burris Fast Fire: What I don't like about this is the on - off switch. Gamesmen, whose pistols live in gun safes or in gun bags will love that feature but it is a potential death trap to a man whose gun lives in the holster. In testing we had these “on-off” switches get turned off inadvertently. If you opt for this unit, I strongly advise getting the traditional BUIS system.
Insight MRDS: They seemed less robust and more complicated than the Trijicon. The manual dot adjustment is not necessary on something to go on a pistol. For this application any on-off, or adjustment is ill-advised. It has a good feature of top loading battery, but the footprint requires more room on the slide. The battery life on them is not as good as on the Trijicon.
The C-Mores I examined seemed to vary greatly in clarity and brightness. Something I attributed to battery at first but I was told by several sources that I trust that that is simply how they are...some come out really clear and bright...others not so much. That the clear and bright ones always seem to go to the gun writers and spec-ops people. That if true, is totally unsatisfactory as far as I am concerned.
Does milling the slide negatively affect endurance/reliability? – Not in my experience. I have three guns set up like this with many thousands of rounds with no problems at all. The easy thing for the undecided to do if they are running 1911 or Glocks is to opt for an aftermarket slide
What options do I have for sight? Anything you want to install on your slide we can do. As I said, we think the Trijicon is the best unit out there, but if you would like something else we will not only provide it, but also install it for you. For more information call the office and ask.
What happens when the sight gets wet? Depending on the red dot unit. With a Trijicon – Nothing. We took the RMR equipped Glock and dunked it in a bucket of water, and then shot steel at 100 yards. Other red dot sights may not have this level of water resistance.
Also, how much of an issue is fogging – We have not had any problems with fogging and we have travelled extensively with the RMR Glock this year to various time zones, climates, etc.
Warranty issues and procedures – TSD warranties our installation for workmanship. If you go out of your way to break it (like hammering nails or dropping from a jet plane or something, its on you). Each red dot manufacturer will have their own warranty.
Field testing on larger calibers like full loads out of a G20. – We have installed these (Trijicons) on all models of Glocks including 10mm and 357 SIG. Users have had no problems or issues.
One Source Tactical’s Technical Services Division offers three levels of red dot sight installation.
Option One is the Red Dot sights and BUIS installed in the traditional manner (our choice).
Option Two is the BUIS installed in front of the Red Dot sight.
Option Three is Red Dot sight only and no BUIS.
These can be installed on Glock models, Springfield XDs, Smith & Wesson MP, FN Pistols, and 1911 systems. Other weapon platforms are in development. The cost of installation depends on the red dot unit selected and the installation option. Some weapons require more labor.
Finally, the end package can be finished in black, olive drab green, or coyote tan.
