From The New Rifleman

I have had the Six Second Mount for a few months now. I have put several hundred rounds down range on a otherwise stock Glock to try my hand at the latest and greatest of pistol enhancements.

The mount has worked well. It introduces a few notable upgrades for the shooters who are willing to sacrifice portability for performance. Not quite a race gun, but not a clean slide melt RDS system… it fits somewhere in between. So what’s the point?

The story from ALG defense is that a certain counter terrorism unit liked the performance of a RDS on their Glock, but they encountered frequent failures of the RDS, so they approached Geisselle for a solution. The solution was introduced from their sister company ALG defense as the SSM. I don’t know what G forces are produced on a red dot as it slams to the rear of slide travel and then is suddenly slammed forward back into battery, but suffice to say I think that battering a small electronic optic like that, no matter how hardened it may be, will likely lead to failure sooner than how the SSM mount isolates its RDS from movement.

Our RDS for the SSM is mounted as low as possible over the slide and the only movement the RDS will see is the movement of wrist flexion and whatever amount of travel the grip and frame of the G17 see in your hand. It’s isolated and free and clear of the damaging G forces that slide mounted systems will experience.

The SSM’s lattice work frame extends down to the plastic Glock rail where it clamps in place over it to offer a picatinny rail mounting solution for all manner of lights and lasers, etc. The two points of hard contact for the mount are the trigger pin, which is replaced by the ALG system, and the front rail which is another pin that clamps over the aforementioned Glock rail.

So it’s cool looking, and offers a bulky way to attach a light and a laser, so how is that better than a svelt slide mounted setup other than red dot durability?

Well, looking past that very important point of RDS durability, it does offer unique shooter advantages. The weight of the system, especially with a light or laser mounted up front, mutes the muzzle flip significantly. With the muting of recoil, we have much less visual deviation with the red dot. It dances up and down, but it is very easy to track. The foreward weight bias keeps in securely in the window of the RDS. Having the RDS in a fixed spot helps you to keep track of that dot better than if it was driving back and forth on a reciprocating slide. A muzzle device would further reduce flip, and this mount could run in Open USPSA just fine, I think.

10 yards out as fast as possible. I’m not proud as 10 yards isn’t impressive, but I’m not ashamed either. I would be happy to examine my groupings like these on a dead assailant. Critique my performance even while I wait for the authorities.

Having a RDS mounted up top gave me a great deal of precision at all distances and allowed 100 yard shots to be, well, too easy. I had a fifteen yard zero and at 100 yards I aimed at the head to drop 9mm squarely into the torso. My shooting buddy called out the shots to ensure I was getting hits and… I was, over and over. At this point several onlookers put down their equipment to watch my fancy ray gun, and they watched and commented as hit after hit was called out at 100. The precision made hitting the human silhouette child’s play.

So what else does it do?

The rail and light mount being permanently attached also allows you to zero a light and a laser together for you high speed types with night vision. Apparently the Glock rail is prone to losing zero with fancy IR lasers… according to the customers who approached Geisselle.

The biggest hurdle is the size and the weight. With G17, rail, TLR-1 light, and PA red dot, it weighs in at 32.9 oz or 2.06 lbs unloaded without a magazine. Rock in a fully loaded G17 magazine and we are at 42.8 oz or 2.68 lbs.

How do we carry the weight of the SSM widget system? We need a good holster. I approached Vigilance Tactical in Elizabethtown PA for a custom solution, and they delivered two holsters which do a fantastic job of carrying the G17 with and without light attached. After a brief jog in the mail to Recoil magazine, my light bearing holster, dubbed the Nocturnal Sentry 6, was sent back to me and added to Vigiliance Tactical’s model listings.  Yes, that is my Glock pictured on their website. Thanks, I’m a proud parent.

The Vigilance Tactical holster was the last piece of the puzzle missing to make the SSM more than just a nite stand gun. The Vigilance Tactical kydex gives me a great holster for the SSM and offers some portability / concealability under a coat in winter. Having both the slimmer model  Sentry 6 for sport, and the full on tactical model with thum-break for the full SSM Kit, I have options. Vigilance Tactical did fantastic work and retention is strong. Aesthetically, it looks great. Some of the other holsters I have seen for the SSM look, well… awkward and crappy.

The Vigilance Kydex tied this project together. Special thanks to Vigilance Tactical.

Wrapping up, the SSM is a full-on kit for someone who is looking for every advantage in a fighting pistol. It mutes recoil very well, minimizes dot loss from slide reciprocation, and increased red dot longevity / lifespan by isolating it from harsh recoil. The costs are increase weight, bulk, cost, and complexity over slide mounted setups, but if you want to carry something that will last you out in the wasteland, go with the SSM and eat the weight. If you need a slimmer gun, then it’s not suitable for your goals. I can see this as a perfect firearm for a recoil sensitive shooter in a home defense environment as well.

The SSM offers lot’s of dirty firepower on tap for the more recoil sensitive shooting soul.

    I remember thinking these were probably a bulky but more reliable long-term solution than the slide-mounted optics. I’m still surprised at how durable even the chinesium optics have been – let alone Trijicon and similar.
